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!
