笨方法学python - 02

二、注释和井号

输入：

# A comment, this is so you can read your program later.
# Anything after the # is ignored by python

print('I could have code like this.') # and the comment after is ignored

# You can aldo use a comment to "disable" or comment out a piece if code :
# print("This won't work")

print('This will run')

　　

结果：

I could have code like this.
This will run

　

注释的作用（井号的作用）：

　　说明代码

　　临时禁用代码
