通过python函数打印类对象内容

class MyClass:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    
    def __str__(self):
        return f"MyClass(name={self.name}, age={self.age})"
    
    def __repr__(self):
        return f"MyClass(name={self.name}, age={self.age})"

obj = MyClass("John", 25)
print(obj)  # 调用__str__()方法打印对象的可读性较好的描述
print(repr(obj))  # 调用__repr__()方法打印对象的准确和详细的描述

MyClass(name=John, age=25)
MyClass(name=John, age=25)
