Question

代码import reletters = ["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 splitCoordlocation = "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

Answer 1

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())
