Python comment: How to write comments in Python

In Python, a line starting with # is regarded as a comment.

a = 1
b = 2

print(a)
# print(b)

In the above code, print(b) is a comment and not skipped in processing.

Or the paragraph between ''' is a comment.

a = 1
b = 2

print(a)

'''
This paragraph is a comment.
print(b)
'''

So Python comment has 2 types: line and paragraph.

Most programming editors like PyCharm color a line or paragraph comment differently.
