What do the python comment characters mean?

Comments in Python include single-line comments and multi-line comments. Single-line comments in Python start with #, and multi-line comments use three single quotes ''' or three double quotes """ to separate the comments. Bracketed. The #, ''' and """ symbols here are comment characters.

Example:

# 这是一个注释
print("Hello, World!")

#!/usr/bin/python3 
'''
这是多行注释，用三个单引号
这是多行注释，用三个单引号

'''
print("Hello, World!")

#!/usr/bin/python3 
"""
