删除python中特殊字符之间的字符串

Question

我有类似这样的字符串

mystring = "CBS Network Radio Panel;\ntitle2 New York OCT13W4, Panel Weighting;\n*options; mprint ls=max mprint;\n\n****************************************out; asd; ***hg;"

我想删除*和之间的字符串; 输出应该是

"CBS Network Radio Panel;\ntitle2 New York OCT13W4, Panel Weighting;\ mprint ls=max mprint;\n\n asd;"

我试过这段代码

re.sub(r'[\*]*[a-z]*;', '', mystring)

但它不起作用。

Answer 1

你可以用

re.sub(r'\*[^;]*;', '', mystring)

查看Python演示 ：

import re
mystring = "CBS Network Radio Panel;\ntitle2 New York OCT13W4, Panel Weighting;\n*options; mprint ls=max mprint;\n\n****************************************out; asd; ***hg;"
r = re.sub(r'\*[^;]*;', '', mystring)
print(r)

输出：

CBS Network Radio Panel;
title2 New York OCT13W4, Panel Weighting;
 mprint ls=max mprint;

 asd;

r'\\*[^;]*;' pattern匹配文字* ，后跟零个或多个字符以外的字符; 然后是; 。
