Question

我正在编写代码，并试图将输入变量（YourName）重新分配为仅包含字母，并忽略任何数字（如果有意义）

while YourName == None:
    YourName = (input("But before we begin, what is your name?:")) #The name can be anything.
    YourName = YourName.capitalize()
    YourName = ''.join(filter(str.isalpha(YourName), input))

但是当我运行它时，它会产生“方法”不可迭代的问题。

我该如何解决

Answer 1

您可以使用re

import re

YourName = None

while YourName == None:
    YourName = (input("But before we begin, what is your name?:")) #The name  can be anything.
    YourName = YourName.capitalize()
    YourName = re.sub(r'\d+', '', YourName)
    print(YourName)

样本输出

But before we begin, what is your name?:ada64782jhadas
Adajhadas

Answer 2

如果要使用过滤器，则该行应如下所示

YourName = ''.join(filter(str.isalpha, YourName))

完整程序

YourName = None

while YourName == None:
    YourName = (input("But before we begin, what is your name?:")) #The name  can be anything.
    YourName = YourName.capitalize()
    YourName = ''.join(filter(str.isalpha, YourName))
    print(YourName)

样本输出

But before we begin, what is your name?:1231af 45 sdfsd
afsdfsd

注意：您错过了空格
