这是一个创建于 2702 天前的主题，其中的信息可能已经有所发展或是发生改变。
class A:
def __init__(self):
self.name = 'test'
def method(self):
print("method print")
Instance = A()
print(getattr(A, 'method', 'default')())
上面这段代码输出如下，请问要怎么修改才能使得 print 语句可以显示 method 函数的执行结果呢？谢谢
Traceback (most recent call last):
File "d:\Python3\t1.py", line 9, in
print(getattr(A, 'method', 'default')())
TypeError: method() missing 1 required positional argument: 'self'

给楼主贴一段代码吧
#!/usr/bin/python class test: def method(self): print('hello world') a=test() print(getattr(a,'method','default')()) print(getattr(test,'method','default')()) 输出结果 hello world None Traceback (most recent call last): File "/usercode/file3.py", line 8, in <module> print(getattr(test,'method','default')()) TypeError: method() missing 1 required positional argument: 'self' 楼主你自己的代码需要传递实例 |
