我遇到了一个错误：“TypeError：'str' 对象不可调用”-Python

Question

I'm really confused. I made classes similar to this the one with this one with no errors. So I don't see the problem with this one. Please help!

class champ_info:
    def __init__(self, name):
        self.name = name

    def name(self):
        print({self.name}) #I also tried using it with out the {}

v = champ_info('henry')
v.name()

Answer 1

You have an attribute with the same name as a method. When you assign self.name its object shadows the function object you really wanted.

class champ_info:
    def __init__(self, name):
        self.name = name    # <-- this shadows the same-named method

v.name() translates to (1) get object referenced by "name" (its the string 'henry' ) and (2) call that object. You can't call a string, so boom.

To solve, just come up with a better name for the method, hopefully something that gives a good hint of what it does.

class champ_info:
    def __init__(self, name):
        self.name = name

    def print_me(self):
        print(f"{self.name}")

v = champ_info('henry')
v.print_me()
