Python 的传址和传值疑问

[qsnow6]

import random


class MyFun(object):

    def __getattr__(self, key):
        if key == 'random':
            return random.random()
        else:
            pass

f = MyFun()
f.random

如上代码

如何把 f.random 传给一个变量，比如a，然后以后调用 a 就执行 f.random?

试过浅拷贝、深拷贝都没用。。

@qsnow6 那么这个样子呢，改成计算属性好了

class WTF(object):
def __init__(self):
pass

@property
def user_agent(self):
return UserAgent().random


wtf = WTF()
wtf.user_agent # call user_agent()

__repr__ 不是像你这么用的

Called by the repr() built-in function to compute the “ official ” string representation of an object. If at all possible, this should look like a valid Python expression that could be used to recreate an object with the same value (given an appropriate environment). If this is not possible, a string of the form <...some useful description...> should be returned. The return value must be a string object.

Python 是按 assignment 传的

[junnplus]

property 应该是正解吧

@cheetah Yep ！！！ a()！！！
