python:实例的返回值[重复]

您需要实现 __str__(self) 方法如下:

class Example():

def __init__(self):
    self.name = "Ninja Warrior"

# add special method to return self.name as a default value of Example()
def __str__(self):
    return self.name

print(Example().name)
# Ninja Warrior

print(Example())  # This is what I want to do
# Ninja Warrior

我想你在找 __str__

class Example():

    def __init__(self):
        self.name = "Ninja Warrior"

    def __str__(self):
        return self.name

    # add special method to return self.name as a default value of Example()

print(Example().name)
# Ninja Warrior

print(Example())  # This is what I want to do
# Ninja Warrior
