python正则表达式模块,拆分字符串,

re.split()eg:s = '1, 2, 3, 4'

拆分组成数字list:strs = re.split(', ', s);

print(strs);

结果:['1', '2', '3', '4']

转成int行list:strs = list(map(int, strs));

print(strs);

结果:[1, 2, 3, 4]

如果strs中有多个分隔符,

模式串中间应用“|”分隔

各个分隔字符(或分隔字符串):eg:strs = '[112, 236, 372; 131]';

strs = re.split(', |; |||');print(strs);

结果: ['', '112', '236', '372', '131', '']

去除首尾空字符串:strs.remove(''); 

####一次只能去除一个空串
