python中反斜杠是什么意思

来源:互联网

1、python本身使用\来转义一些特殊字符,比如在字符串中加入引号的时候

s = 'i\'m superman'print(s)    # i'm superman

2、Python中反斜杠也可以用在一行结尾做续行符使用。

例:

hello = "This is a rather long string containing\n\several lines of text just as you would do in C.\n\    Note that whitespace at the beginning of the line is\ significant."  print(hello)

注意,其中的换行符仍然要使用 \n 表示——反斜杠后的换行符被丢弃了。以上例子将如下输出:

This is a rather long string containingseveral lines of text just as you would do in C.    Note that whitespace at the beginning of the line is significant.
