您所说的(我认为)被称为docstrings(感谢Boud提供链接)。
def foo(): """This function does absolutely nothing"""
现在,如果您
help(foo)从解释器中键入内容,您将看到我放入函数中的字符串。您还可以通过以下方式访问该字符串
foo.__doc__
当然,字符串文字就是这样-文字字符串。
a = "This is a string literal" #the string on the right side is a string literal, "a" is a string variable.
要么
foo("I'm passing this string literal to a function")可以通过多种方式定义它们:
'single quotes'"double quotes"""" triple-double quotes """ #This can contain line breaks!
甚至
#This can contain line breaks too! See?''' triple-single quotes '''
