    for i in range(024,027):
    print i


    为什么输出的是
    20
    21
    22

    而不是
    24
    25
    26

    前面不加 0 却不会报错,怎么破???

    These are numbers represented in base 8 (octal numbers). For example,

    011 is equal to 1*(8**1) + 1*(8**0) = 9,
    0100 is equal to 1*(8**2) + 0*(8**1) + 0*(8**0) = 64,
    027 is equal to 2*(8**1) + 7*(8**0) = 16 + 7 = 23.
