python中井号怎么用

注释在编程中是很重要的部分。它能告诉你这段代码是干什么用的，或者用来删除一部分你暂时不需要执行的代码。下面演示的是如何在

python中使用注释：

# 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 also use a comment to "disable" or comment out a piece of code:
# print "This won't run."

print "This will run."

由上面可知，Python中的#是用来写注释的，而且一般是写单行注释。python学习网，免费的python学习网站，欢迎在线学习！
