怎么简单继承第三方库?

继承库,不是类!

import uiautomator2
class expand(uiautomator2):
    def unlock(self):
        d.screen_on()
        for i in range(23):
            if d.info['currentPackageName'] in ['com.android.systemui', 'android']:  #
                logging.info('解锁屏幕')
                d.swipe_ext("up", scale=0.9)
                d.unlock()
            else:
                logging.info('已解锁')
                return True
            time.sleep(1)

TypeError: module() takes at most 2 arguments (3 given)
会出错!我想给库加个功能,不想修改库,不然每次升级都要去修改!
找遍了,都是说怎么继承类的

最佳答案

簡單的作法如下

class A():
    def __init__(self):
        pass
    def unlock(self):
        print("Old unlock")

class B(A):
    pass

class C(A):
    def unlock(self):
        print("New unlock")
        super().unlock()

d = C()
d.unlock()
New unlock
Old unlock

import uiautomator2 as u2
import logging
import time
def connect(addr=None):
    global d
    d = u2.connect(addr)
    d.unlock=unlock
    return d

def unlock():
    d.screen_on()
    for i in range(23):
        if d.info['currentPackageName'] in ['com.android.systemui', 'android']:  #
            logging.info('解锁屏幕')
            d.swipe_ext("up", scale=0.9)
            d.unlock()
        else:
            logging.info('已解锁')
            return True
        time.sleep(1)

想到一个方法,新建一个init.py
然后导入,就可以了
不过这个方法应该是有问题的
init ][ unlock ][ INFO ][ 14 ][ 解锁屏幕
init ][ unlock ][ INFO ][ 14 ][ 解锁屏幕
init ][ unlock ][ INFO ][ 18 ][ 已解锁
init ][ unlock ][ INFO ][ 18 ][ 已解锁
init ][ unlock ][ INFO ][ 18 ][ 已解锁
这些都只出现一次的应该!

觉得这个问题的标题不对 ?!

下面这个例子如何 ?

>>> import uiautomator2 as u2
>>>
>>> class Device(u2._Device, u2._AppMixIn, u2._PluginMixIn, u2._InputMethodMixIn, u2._DeprecatedMixIn):
...     def unlock(self):
...         print('New unlock')
...         return    # function stop here just for verification !!!
...         self.screen_on()
...         for i in range(23):
...             if self.info['currentPackageName'] in ['com.android.systemui', 'android']:  #
...                 logging.info('解锁屏幕')
...                 self.swipe_ext("up", scale=0.9)
...                 # super().unlock()    # call which `unlock` ? 
...             else:
...                 logging.info('已解锁')
...                 return True
...             time.sleep(1)
...
>>> u2.Device = Device
>>>
>>> device = u2.connect("http://127.0.0.1:8080")
>>> device.unlock()
New unlock
