“元组”对象不支持项目分配和 NameError:name

Question

代码

import re

letters = ["x","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P"]

def coordSplit(coord):

        splitCoord=[]

        match = re.match(r"([A-Z]+)([0-9]+)", coord, re.I)

        if match:

            splitCoord = match.groups()

        count=0

        for letter in letters:

            if splitCoord[0] == letter:

                print(splitCoord[0])

                splitCoord[1] = str(count) #it can not change this value to a number NameError: name xxx is not defined

            count = count + 1

        return splitCoord

location = "H6"

coordSplit(location)

我一直在把它放在一起，但我一直收到错误“NameError：name splitCoord is not defined”和“'tuple' object does not support item assignment”任何人都可以帮忙

这一行：splitCoord = match.groups()返回一个元组。因此这一行：splitCoord[1] = str(count)不会工作，因为元组是不可变的。使用：splitCoord = list(match.groups())
