    for airport in list_airports:
         new_link = link.replace('anywhere', airport, 1)
         new_link = new_link[:-16]

         for date in list_date:
               new_link = new_link.replace('2', date, 1)
               print(new_link)

Answer 1

你让事情变得比需要的更复杂了

list_airports = ['BCN', 'REU', 'RMU', 'VLC', 'IBZ', 'ALC', 'AGP', 'MAD']
list_date = ['2021-08-10/2021-08-11', '2021-08-11/2021-08-12' ]

for airport in list_airports:
    for date in list_date:
        print( f"https://www.kayak.it/explore/MIL-{airport}/{date}")

输出：

将“print”更改为“yield”，您可以使其成为返回生成器的易于使用的函数
