Python中帶有多個分隔符的拆分字符串我在網上找到了一些答案，但我對正則表達式沒有經驗，我認為這是這里所需要的。我有一個字符串，需要用‘；’或‘來分隔，也就是說，它必須是分號或逗號，后面跟著空格。沒有尾隨空格的個別逗號應保持不變。示例字符串："b-staged divinylsiloxane-bis-benzocyclobutene [124221-30-3], mesitylene [000108-67-8]; polymerized 1,2-dihydro-2,2,4- trimethyl
quinoline [026780-96-1]"應拆分為包含以下內容的列表：('b-staged divinylsiloxane-bis-benzocyclobutene [124221-30-3]' , 'mesitylene [000108-67-8]', 'polymerized 1,2-dihydro-2,2,4- trime
thyl quinoline [026780-96-1]')

import re
re.split('; |, ',str)最新情況：
>>> a='Beautiful, is; better*than\nugly'>>> import re>>> re.split('; |, |\*|\n',a)['Beautiful', 'is', 'better', 'than', 'ugly']

>>> import re>>> delimiters = "a", "...", "(c)">>> example = "stackoverflow (c) is awesome... isn't it?" >>> regexPattern = '|'.join(map(re.escape, delimiters))>>> regexPattern'a|\\.\\.\\.|\\(c\\)' >>> re.split(regexPattern, example)['st', 'ckoverflow ', ' is ', 'wesome', " isn't it?"]
def split(delimiters, string, maxsplit=0): import re regexPattern = '|'.join(map(re.escape, delimiters)) return re.split(regexPattern, string, maxsplit)
RegexObject.split.
