python - 是什么导致以下代码中的分配错误之前的引用？

问题描述

我在分配之前收到了这个错误，我不知道如何解决它。

目前我还没有尝试过任何东西。如果能回答这个问题将不胜感激。（我只是想填更多的词，以便可以发布）

这是error code我得到的：

number = int(number)

UnboundLocalError: local variable 'number' referenced before assignment

这是我剩下的代码

    myName = input('Hello, Enter your name to get started')
    if myName.isdigit():
        print('ERROR,Your Name is not a number, please try again')
        print('')
        continue
    break
myName = str(myName.capitalize()) 




print('')
