python中反斜杠是什么意思

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

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 containing several lines of text just as you would do in C.     Note that whitespace at the beginning of the line is significant.
