Python Statements and Comments


In this tutorial, we will go to discuss python statements (Instructions to perform specific tasks) and comments.

What is Statements in Python:

Statements in python are instructions that perform a specific task. A statement can be a single line of code or a block of code. 

In Python, statements are executed one by one in the order in which they are written. 

In writing, statements use of meaningful and descriptive statements can improve the maintainability of your code and make it easier to debug.

Types of Statements:

There are several types of statements in Python, including:

  • Assignment statements: These statements assign a value to a variable. For example: “x = 10”
  • Conditional statements: These statements allow you to control the flow of your program based on certain conditions. For example: “if x > 5: print(‘x is greater than 5’)” (here all the values greater than 5 printed).
  • Loop statements: These statements allow you to repeat a block of code multiple times. For example: “for i in range(5): print(i)” (here code repeats 5 times).
  • Function definition statements: These statements define a function and specify its behavior. For example: “def square(x): return x * x”
  • Return statements: These statements return a value from a function. For example: “return x * x”
  • Import statements: These statements import modules or packages into your program. For example: “import math”
  • Exception handling statements: These statements handle exceptions and errors in your program. For example: “try: … except: … “
  • Pass statements: These statements do nothing and are used as placeholders. For example: “pass”

These are the main types of statements in Python. Each type of statement has a specific use and purpose and can be combined to create complex programs.

Python Comments:

In Python, comments are used to add descriptive text to your code. They are ignored by the Python interpreter and do not affect the execution of your program. 

Comments are a useful way to add explanations and notes to your code, making it easier to understand and maintain.

Types of Python Comments:

There are two types of comments in Python, single-line comments and multi-line comments. 

  • Single-line comments start with the “#” symbol and extend to the end of the line. 
  • Multi-line comments are surrounded by triple quotes (“””).

They are ignored by the Python interpreter and do not affect the execution of your program.


We can write comments by using “#” and triple (“””).

# This is a single-line comment

This is a multi-line comment.
It can span multiple lines and is useful for writing longer explanations or notes.

# Define a variable
x = 10

# Check if x is greater than 5
if x > 5:
    # Print the result
    print("x is greater than 5")
