我正在嘗試從以下文本中提取省份和城市名稱（這是 html，但我刪除了一些轉義字符）。但是，我編寫的正則表達式返回一個空白列表。當我在一個 re 網站（例如https://regex101.com/）上測試代碼時，它似乎可以工作，但是當我在腳本中編寫它時它不起作用。這是我的代碼的縮短版本（html 轉儲要長得多）。任何幫助，將不勝感激。import retext = 'try window.getAreaStat = [provinceName:湖北省,provinceShortName:湖北,confirmedCount:3554,suspectedCount:0,curedCount:80,deadCount:125,comment:待明確地區：治愈 30,cities:[cityName:武漢,confirmedCount:1905,suspectedCount:0,curedCount:47,deadCount:104,cityName:黃岡,confirmedCount:324,suspectedCount:0,curedCount:2,deadCount:5,cityName:孝感,confirmedCount:274,suspectedCount:0,curedCount:0,deadCount:3,cityName:荊門,confirmedCount:142,suspectedCount:0,curedCount:0,deadCount:4,cityName:襄陽,confirmedCount:131,suspectedCount:0,curedCount:0,deadCount:0,cityName:隨州,confirmedCount:116,suspectedCount:0,curedCount:0,deadCount:0,cityName:咸寧,confirmedCount:112,suspectedCount:0,curedCount:0,deadCount:0,cityName:荊州,confirmedCount:101,suspectedCount:0,curedCount:1,deadCount:2,cityName:十堰,confirmedCount:88,suspectedCount:0,curedCount:0,deadCount:0,cityName:黃石,confirmedCount:86,suspectedCount:0,curedCount:0,deadCount:1,cityName:鄂州,confirmedCount:84,suspectedCount:0,curedCount:0,deadCount:1,cityName:宜昌,confirmedCount:63,suspectedCount:0,curedCount:0,deadCount:1,cityName:恩施regex = "((?<=provinceName:)|(?<=cityName:)).*?(?=,)"province = re.findall(regex, text)print(province)['', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '']

從此答案中，re.findall將返回所有捕獲的組。我在https://regexr101.com中嘗試了您的正則表達式，它都返回空白捕獲組。
您可以通過添加使用非捕獲組(?:...)
regex = "(?:(?<=provinceName:)|(?<=cityName:)).*?(?=,)"
