Comment Statement In Python
When writing Python programs, comments are like notes you leave for yourself or others. They don’t affect how the program runs because Python simply ignores them. Instead, they serve three important purposes:
- Making code easier to understand
- Explaining tricky parts of the logic
- Temporarily disabling (skipping) certain lines while testing
What Are Comments in Python?
A comment is a piece of text in your code that Python doesn’t execute.
They’re written by starting the line with the # symbol.
Example: Single-Line Comment
# This program prints a greeting
print("Hello, World!")
Here, the first line is ignored by Python. Only the
print() statement runs.Comments at the End of a Line
Comments can also appear after code on the same line:
print("Hello, Python!") # This is an inline comment
Python executes only the print("Hello, Python!") part, but skips the text after #.
Using Comments to Disable Code
Sometimes you don’t want a line to run (maybe for testing). Just add # in front of it:
#print("This will not run")
print("This line will run")
Multi-Line Comments in Python
Unlike some languages (like Java or C), Python doesn’t have a special syntax for block comments.
But you can achieve multi-line commenting in two ways:
