#未对输入参数进行检查，有必要可自行完善

import string

ls = list(string.ascii_uppercase)

def ts2d(s):
    sl = len(s)
    result = 0
    for i in range(sl):
        result += (ls.index(s[ i ]) + 1) * 26 ** (sl - i - 1)
    return result

print(ts2d('ABC'))

def d2ts(num):
    result = ''
    while num > 26:
        s = num % 26
        result += ls[ s - 1 ]
        num //= 26
    return (result + ls[ num - 1 ])[ ::-1 ]

print(d2ts(731))
