Question

为什么此函数返回LinkedIn而不是Amazon？

def hey(location):
        location = "LinkedIn"
        answer = "Welcome to " + location
        return answer
        
print(hey("Amazon"))

Answer 1

因为您在函数内部将location声明为"LinkedIn"。

如果没有为"LinkedIn"输入任何参数，如果您希望location为默认值，请尝试：

def hey(location="LinkedIn"):
    return "Welcome to " + location
