我正在尋找一種列表理解，即根據(jù)列表列表中的索引位置添加一系列數(shù)字，同時單獨保留第二個索引。search_keys = [('1', 'B'), ('1', 'K'), ('1', 'Y')]期望的結(jié)果：new_search_keys = [('11', 'B'), ('12', 'B'), ('13', 'B'), ('14', 'B'), ('15', 'B')... ...('11', 'K'), ('12', 'K'), ('13', 'K'), ('14', 'K'), ('15', 'K')... ...('11', 'Y'), ('12', 'Y'), ('13', 'Y'), ('14', 'Y'), ('15', 'Y')...]我的嘗試帶來了 TypeError: 'type' object is not subscriptable:new_search_keys = [search_keys[i][0] + list(range[1,9]) for i in range(len(search_keys))]

這應(yīng)該可以解決您的問題：-
new_search_keys = [(search_keys[i][0] +str(j), search_keys[i][1]) for i in range(len(search_keys)) for j in range(1,9)]
輸出：-
[('11', 'B'), ('12', 'B'), ('13', 'B'), ('14', 'B'), ('15', 'B'), ('16', 'B'), ('17', 'B'), ('18', 'B'), ('11', 'K'), ('12', 'K'), ('13', 'K'), ('14', 'K'), ('15', 'K'), ('16', 'K'), ('17', 'K'), ('18', 'K'), ('11', 'Y'), ('12', 'Y'), ('13', 'Y'), ('14', 'Y'), ('15', 'Y'), ('16', 'Y'), ('17', 'Y'), ('18', 'Y')添加回答
