Let's get comfortable with Python by writing a quick and simple script. Copy the following code into a text editor and save it as hello.py: #!/usr/bin/python user = "<your name>" print "Hello " + user + "!" Line
然而这还不行,因为正则表达式本身要作为字符串使用,反斜杠在Python字符串中也有转义作用,所以必须要对\\s.*做再次转义:\\\s.*;回到\section字符串,他作为被匹配的字符串,里面的转义符号也应当取消,所以它在Python字符串中的正确写法是\\section,完整的程序如下所示: ...
