Python字符串文字和转义序列

Question

我有一个字符串

'“不，谢谢，妈妈，”我说，“我不知道需要多长时间。”

我将它分配给变量foobar

>>> foobar = """'"No, thanks, Mom," I said, "I don't know how long it will take."'"""

但是当我打印时，我得到了

>>> foobar
'\'"No, thanks, Mom," I said, "I don\'t know how long it will take."\''
>>>

如何准确打印与我指定的字符串相同的值？

Answer 1

要打印字符串，请使用... print：

>>> foobar = """'"No, thanks, Mom," I said, "I don't know how long it will take."'"""
>>> print(foobar)
'"No, thanks, Mom," I said, "I don't know how long it will take."'

如果您只输入foobar，Python会打印foobar的representation。该表示被设计为有效的Python代码和/或用于调试，并不意味着输出给用户。

Answer 2

>>> print foobar

foobar本身在字符串上调用repr，该字符串使用escapes打印字符串。 print foobar会在字符串上调用str。

Answer 3

打印相同的值。它只显示转义的单引号，以区别于cmd行用于显示字符串的单引号。
