Comments in Python are used to add explanatory notes to code and are ignored during program execution.
- It enhance the readability of the code.
- It can be used to identify functionality or structure the code-base.
- It can help understanding unusual or tricky scenarios handled by the code to prevent accidental removal or changes.
- It can be used to prevent executing any specific part of your code, while making changes or testing.

Single Line Comments
Single line comments starts with hashtag symbol #.
# sample comment
name = "geeksforgeeks"
print(name)
Output
geeksforgeeks
Multi-Line Comments
Python does not have a dedicated syntax for multi-line comments. However, they are commonly written using multiple # symbols or unassigned string literals.
1. Using multiple hashtags (#)
We can use multiple hashtags (#) to write multiline comments. Each and every line will be considered as a single-line comment.
# Python program to demonstrate
# multiline comments
print("Multiline comments")
2. Using String Literals
Python ignores the string literals that are not assigned to a variable. So, we can use these string literals as comments.
