python - perl 到 python...我该怎么做？

Question

我正在尝试学习 python，但不太了解语法。什么相当于:

my $string='this one this that this here ';
while($string=~/this\s+(.*?)\s+/g){
    print $1."\n";
 }

打印:

one
that
here

Answer 1

试试 re 模块。我认为这是等效的，对 string 的一些副作用取模:

import re
string = "this one this that this here "
for match in re.finditer(r"this\s+(.*?)\s+", string):
    print match.group(1)
