关于python：“UnboundLocalError：赋值前引用的局部变量’输入’”

“UnboundLocalError: local variable 'input' referenced before assignment”

当我运行代码时，会收到以下错误：

1 2	linechoice = input("What password do you want to delete?: ")

相关讨论

您正在为中的变量input分配一个字符串。

1

3

y_n = input = ("Do you want to save these changes?
y/n
")

input现在有'Do you want to save these changes?
y/n
'的价值。

但是，您也在调用内置函数inputin

1 2	linechoice = input("What password do you want to delete?: ")

考虑更改变量的名称以避免这些冲突。

查看程序的上下文，您可能期望

1
2
3

y_n = input("Do you want to save these changes?
y/n
")

而不是

y_n = input = ("Do you want to save these changes?
y/n
")
