Indentation and
Comments

1.What is Indentation of Python?
• Indentation refers to the spaces at the beginning of a code
line.
• the indentation in Python is very important.
• Python uses indentation to indicate a block of code.
• Python will give you an error if you skip the indentation.
• Example:
• if 5 > 2:
• print("Five is greater than two!")

2. What happens if you don't follow the
correct indentation in Python?
• Incorrect indentation in Python leads to indentation errors and
affects the program's structure.
• Example:
• if 5 > 2:
• print("Five is greater than two!")

3. What is the purpose of indentation
in Python?
• Code Structure
• Readability
• No Explicit Braces or Delimiters
• Example:

# Example of indentation in a conditional
statement
if x > 0:
print("x is positive")
y = x * 2
print("Twice x is", y)
else:
print("x is non-positive")
y = 0
print("Y is", y)

5.What are the Rules for Indentation?
• minimum one space is necessary to represent an indented statement.
• The first line of python code cannot have indentation.

6.What is Comments in python?
• Comments can be used to make the code more readable.
• Comments can be used to prevent execution when testing code.
• Indicates the symbol is #.

Example:""" print(“Hello World”)
print(“Good Evening”)
print(“Good Night”)"""

9.What is the difference between
single-line and multi-line comments in
Python?
Single-line Comment Multi-line Comment
• Multi-line comments are created using
triple quotes(” ” ”)
• Example:
""" print(“Hello World”)
print(“Good Evening”)
print(“Good Night”)"""
• Single-line comments start with a hash
symbol(‘#’)
• Example:#print(“Good Morning”)
• print(“Hello Mumbai”)
