程序里的注釋是很重要的。它們可以用自然語(yǔ)言告訴你某段代碼的功能是什么。在你想要臨時(shí)移除一段代碼時(shí),你還可以用注解的方式將這段代碼臨時(shí)禁用。接下來(lái)的練習(xí)將讓你學(xué)會(huì)注釋:
1 2 3 4 5 6 7 8 9 | # 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."

$ python ex2.py
I could have code like this.
This will run.
