是否有其他更简单的方法来删除除第一行以外的所有表行?

df = df.drop([1, 2, 3, 4, 5, 6 ,7 ,8 ,9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
                  21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40,
                  41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60,
                  61, 62, 63, 64, 65, 66, 67, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80,
                  81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98], axis = 0)

df.drop(df.index.to_list()[1:], axis=0)

正如Nick所写:df = df.loc[[0]]工作正常。
