Question

phone_letters =[" ", "1", "ABC","DEF","GHI","JKL","MNO","PQRS","TUV","WXYZ","*","0","#" ]
key = 0
string = input("Enter a Letter: ",)

while key < 10 :
        if string in phone_letters[key]: 
            print(key)
            return key
        else:
            key = key+1

        return "not found"

我遇到错误'return' outside function；我检查了缩进，但错误仍然存在。

Answer 1

return可能仅在语法上嵌套在函数定义中

您的返回未嵌套在函数内。因此，错误。

如果要显示文本，可以使用print("not found")。
