Basic Characteristics Of Python Programming Syntax
Python syntax refers to the set of rules that dictate how Python code should be written to ensure it is both syntactically correct and logically meaningful. Here are key aspects of Python syntax:
Indentation In Python Syntax
When writing programs, we quite often have to provide blocks of code to indicate elements such as functions, loops, conditional statements, etc. But how? Well, in Python, we use indentation to mark blocks of code. In other words, consistent indentation is essential for defining the code structure.
Unlike many other programming languages that use braces or keywords, Python relies on the level of indentation to determine the scope of code blocks. We make use of a number of leading whitespace (either tabs or spaces, not both) to establish the line's indentation level. By default, a single indent level in Python is four spaces (or one tab). For example-
if x > 0:
print("Positive number")
else:
print("Non-positive number")
Whitespace
Python is whitespace-sensitive, and the amount of indentation matters. Consistency in indentation is crucial for the correct interpretation of code blocks. Mixing tabs and spaces or inconsistent indentation can lead to syntax errors.
# Good indentation
if x > 0:
print("Positive number")# Incorrect indentation (may cause an error)
if x > 0:
print("Positive number")
In the first block, we have four spaces (i.e., one tab) to indent the if-statement, which is the correct way to indent. In the second block though, we have used one tab and a whitespace, leading to incorrect indentation.
Colon (:) For Code Blocks
We use a colon in Python syntax to denote the beginning of a code block, such as in the case of loops, conditionals, and function definitions. The indented lines that follow the colon form the body of the block. For example-
for i in range(5):
print(i)
Comments In Python
Coders, programmers, or software developers writing codes in Python can leave remarks (description or annotation) for fellow programmers, just like in any other programming language. However, in contrast, comments in Python start with the hashtag symbol (#) and are used to provide explanations or documentation within code.
They are included to make the source code more human-readable, while the Python interpreter ignores them. Python allows both single-line (or end-of-line) and multi-line (block) comments. For example-
# This is a single-line comment
"""
This is a
multi-line comment
"""
Variables & Assignment
In Python, variables are created simply by assigning values to the names of variables using the assignment operator (=). Since it is dynamically typed, the variable types are inferred at runtime. For example-
x = 10
name = "Shivani"
Data Types
Python supports various data types, including integers, floats, strings, lists, tuples, dictionaries, and more. The syntax for creating and manipulating these data types is integral to Python programming. Note that since
# List creation
numbers = [1, 2, 3, 4, 5]# String concatenation
greeting = "Hello, " + name
Functions
In Python, functions are defined using the def keyword, followed by the function name and parameters. Also, the function body/ lines of code must have a consistent indentation. For example-
def add_numbers(a, b):
return a + b
Conditional Statements
Python uses if, elif (else if), and else for conditional statements. The indentation determines the blocks of code associated with each condition. For example-
if x > 0:
print("Positive number")
elif x == 0:
print("Zero")
else:
print("Negative number")
Loops
Python supports for and while loops. The for loop is often used for iterating over sequences, while the while loop is used for repeated execution based on a condition. For example-
# For loop
for i in range(5):
print(i)# While loop
while x > 0:
print(x)
x -= 1
Code Sample:
ZGVmIGNhbGN1bGF0ZV9zdW0obnVtYmVycyk6DQogICAgIyBJbml0aWFsaXplIGEgdmFyaWFibGUgdG8gc3RvcmUgdGhlIHN1bQ0KICAgIHRvdGFsX3N1bSA9IHN1bShudW1iZXJzKSANCiAgICAjIFJldHVybiB0aGUgY2FsY3VsYXRlZCBzdW0NCiAgICByZXR1cm4gdG90YWxfc3VtDQoNCiMgRXhhbXBsZSBsaXN0IG9mIG51bWJlcnMNCm51bWJlcnNfbGlzdCA9IFsxLCAyLCAzLCA0LCA1XQ0KDQojIENhbGwgdGhlIGZ1bmN0aW9uIGFuZCBzdG9yZSB0aGUgcmVzdWx0DQpyZXN1bHRfc3VtID0gY2FsY3VsYXRlX3N1bShudW1iZXJzX2xpc3QpDQoNCiMgUHJpbnQgdGhlIHJlc3VsdA0KcHJpbnQoIlN1bSBvZiBudW1iZXJzOiIsIHJlc3VsdF9zdW0p
Output:
Sum of numbers: 15
Explanation:
In the Python code above,
- The calculate_sum function is defined using the def keyword.
- It takes a list of numbers as a parameter. Inside the function, a variable total_sum is initialized to 0. This variable will be used to store the sum of the numbers.
- A for loop is used to iterate through each number in the given list (numbers). The indentation indicates the block of code belonging to the loop.
- Within the loop, each number is added to the total_sum variable. This process repeats for each element in the list.
- After the loop completes, the function returns the calculated sum (total_sum). An example list of numbers (numbers_list = [1, 2, 3, 4, 5]) is created.
- The calculate_sum function is called with this list as an argument, and the result is stored in the variable result_sum.
- The result is printed using the print statement, showing the sum of the numbers in the list.
Python Syntax Vs. Other Programming Languages
Python's syntax differs from many other programming languages in several ways, emphasizing readability, simplicity, and expressiveness. Here are some key differences in Python syntax compared to other languages:
Feature | Python | Other Languages (e.g., Java, C++) |
---|---|---|
Whitespace Significance | Indentation determines code blocks | Braces {} or keywords (begin, end) determine blocks/ bundles of code |
Explicit Variable Declaration | No explicit declaration is required | Requires explicit type and declaration of variables |
Dynamic Typing | Dynamically typed | Statically typed |
Colon and Indentation | Colon (:) and indentation define blocks | Braces {} or keywords () |
Simplicity and Expressiveness | Emphasis on simplicity and expressiveness | Syntax may be more verbose |
Duck Typing | Follows duck typing philosophy | Explicit type declarations often required |
Semicolons for Line Termination | Not required (newline terminates statements) | Required to terminate statements on the same line |
Extensive Standard Library | Comprehensive standard library | Standard libraries may vary in coverage |
The syntax of languages such as Node.js, Java, and C++ is intricate and requires the user to adhere to particular programming conventions, such as the usage of curly brackets and semicolons at the conclusion of statements. Python, in contrast, lacks such programming conventions. The indentation rules used by Python, are comparable to those of the English language, making it simpler for programmers to grasp.

Some Useful Python Tips & Tricks For Efficient Programming
When writing code from scratch, a developer's life can be greatly simplified by Python's minimalism. However, there are several lesser-known Python techniques that may sway you with their incredible power. In this section, we’ll discuss useful tricks that can help you write short, meaningful codes in Python.
1. Value Swapping: In Python, you can change the values of two variables without using a temporary variable with a straightforward one-liner.
Code:
YSA9IDUKYiA9IDEwCmEsIGIgPSBiLCBhCnByaW50KGEsIGIp
Output:
10 5
Explanation:
In the example above, the one-liner (a, b = b, a) swaps the values of a and b. The values are then assigned to a and b on the right-hand side, which first produces a tuple (b, a) before unpacking it. The values of a and b are consequently switched.
2. Reversing a String: You can reverse a string in Python using slicing with a step of (-1).
Code:
b3JpZ2luYWxfc3RyaW5nID0gIkhlbGxvLCBXb3JsZCEiCnJldmVyc2VkX3N0cmluZyA9IG9yaWdpbmFsX3N0cmluZ1s6Oi0xXQpwcmludChyZXZlcnNlZF9zdHJpbmcp
Output:
"!dlroW ,olleH"
Explanation:
Here, the string is reversed using the [::-1] slicing operation. It reverses the letters' order by beginning at the end of the string and moving backward by -1.
3. List Comprehensions: List comprehensions allow you to create concise lists based on existing lists or other iterable objects.
Code:
c3F1YXJlcyA9IFt4KioyIGZvciB4IGluIHJhbmdlKDEsIDYpXQpwcmludChzcXVhcmVzKQ==
Output:
[1, 4, 9, 16, 25]
Explanation:
Here, a new list is created by square rooting each number in the range of 1 to 5 using the list comprehension [x**2 for x in range(1, 6)].
4. Unpacking Elements: In Python, it's simple to split out the elements of a list or tuple into independent variables.
Code:
YSwgYiwgYyA9IFsxLCAyLCAzXQpwcmludChhLCBiLCBjKQ==
Output:
1 2 3
Explanation:
Here, the elements of the list [1, 2, 3] are unpacked into individual variables a, b, and c. And each variable is assigned the corresponding value from the list.
5. Enumerate: You may loop through an iterative using the enumerate() method in Python, to get the index and value of each element.
Code:
bXlfbGlzdCA9IFsnYScsICdiJywgJ2MnXQpmb3IgaW5kZXgsIHZhbHVlIGluIGVudW1lcmF0ZShteV9saXN0KToKwqAgwqAgcHJpbnQoaW5kZXgsIHZhbHVlKQ==
Output:
0 a
1 b
2 c
Explanation:
In the example above, we iterate over my_list using the enumerate() method, which returns the index and value of each item. While the index variable keeps the element's index, the value variable preserves the pertinent value.
6. Zip: The zip() function in Python combines multiple iterables into a single iterable of tuples, grouping corresponding elements together.
Code:
bGlzdDEgPSBbMSwgMiwgM10KbGlzdDIgPSBbJ2EnLCAnYicsICdjJ10KY29tYmluZWQgPSB6aXAobGlzdDEsIGxpc3QyKQpwcmludChsaXN0KGNvbWJpbmVkKSk=
Output:
[(1, 'a'), (2, 'b'), (3, 'c')]
Explanation:
In the Python program here, the zip() function's List1 and List2 elements are concatenated into tuples. The corresponding items are matched up in the resultant tuples. You can see the tuples as the result by converting the zip object to a list.
Python 2 Vs. Python 3: Which Should You Learn?
The obvious choice for any developer who is starting to learn how to program in Python is Python 3. The language has undergone modifications that make it simpler to produce high-quality code. This is the primary motivation behind the version's creation. The Python community merely needed some time to catch up and update all the third-party libraries that programmers relied on to complete their work.
Most of these third-party libraries were not updated to Python 3 for quite a few years. However, compared to the earlier version, Python 3 is now supported by a wider range of libraries. Additionally, Python 2 is no longer being developed as of the start of 2020. The last version of Python 2 had been in maintenance mode for years by then, and all its new features were added to Python 3. For the most part, you won’t find much Python 2 code in use today.
Now, let us take a look at some key differences between these two languages.
Python 2 |
Python 3 |
It is the more stable and transparent version of the Python programming language. |
It is the future of Python, created to address the design flaws in the previous versions. |
The print syntax is treated as a statement rather than a function, which requires text to be wrapped in parenthesis. E.g., print "Hello" |
The print is explicitly treated as a function and replaced by the print() function in Python 3, which requires an extra pair of parenthesis. E.g., print("Hello") |
ASCII string type is used by default to store strings. |
Unicode is the implicit string type by default. |
It simply returns an integer to the nearest whole number when dividing two integers. |
It makes integer division more intuitive by using true division for integers and floats |
Xrange function reconstructs the sequence every time. |
Xrange is replaced by the range() function in Python 3. |
Python Libraries
The Python libraries refer to a group of connected modules that further have collections of code that may be reused in many programs. For the programmer, it simplifies and makes Python programming more practical to use. This is because, with the use of libraries, we don't have to develop the same code for many programs repeatedly. Python libraries are particularly important when working in domains like machine learning, data science, data visualization, etc.

The simple syntax of Python is straightforward and resembles the English Language closely. Python's syntax differs from various other powerful programming languages, and it enables programmers and software developers to construct programs with fewer lines of code. Python operates on an interpreter system, allowing for the immediate execution of written code. As a result, prototyping in Python may proceed quickly.
Q. What is a data type in Python?
The data types in Python, like all other programming languages, refer to the type of data stored in the variables. In other words, it specifies the kind of information that will be kept in a variable. Numerous different sorts of data types can be used in a program and kept in the memory.
For instance, a person's address is kept as a string of alphanumeric letters, while their age is recorded as a numeric number. Also, Python is a dynamically typed language, meaning that the variable type is assigned at runtime. The built-in or standard data types in Python include-
- Numeric
- Sequence Type
- Boolean
- Set
- Dictionary
- Binary Types( memoryview, bytearray, bytes)
