Single-line comments
Use the # symbol to write a comment. Python ignores everything after # on that line.
# This is a comment!
print("Welcome to Python!")
# The line above prints a greetingWhat gets printed?
Only code runs—comments do not. The previous example prints:
Welcome to Python!Comments help you and others remember what each section does—especially when you revisit projects later.
Multi-line comments
For longer notes, you can use triple quotes (''' or """) as a documentation string (docstring) or block comment.
'''This is a comment that
spans multiple
lines.'''
print("Hello! How are you?")Tip: Temporarily wrap sections of code in triple quotes to “blank out” parts while testing.
