python 10进制与27进制互转

使用python编程实现10进制转27进制
A表示1，B表示2…Z表示26

def _27To10(inputStr):
    inputStr=str(inputStr)
    inputList = []
    for x in inputStr:
        inputList.append(x)
    listLen = len(inputStr)
    count = 0
    for x in range(listLen):
        count = count + (ord(inputList[x]) - ord('a') + 1) * 26 ** (listLen - x - 1)
    return count

def _10To27(inputStr):
    inputStr = int(inputStr)
    yushuList = []
    restStr = ''
    if inputStr < 27:
        restStr = chr(ord('a')+inputStr-1)
    else:
        shang = inputStr // 26
        yushuList.append(inputStr % 26)
        while shang > 26:
            yushu = shang % 26
            yushuList.append(yushu)
            shang = shang // 26
        yushuList.append(shang)
    for x in range(len(yushuList)-1, -1, -1):
        restStr =restStr + chr(yushuList[x]+ord('a')-1)

    return restStr

while True:
    try:
        inputStr = input()
        if inputStr.isdigit():
            print(_10To27(inputStr))
        else:
            print(_27To10(inputStr))
    except:
        break
