在`class`定義體內循環初始化屬性

如何循環class定義體內的初始化屬性？在`class`定義體內循環初始化屬性

假定的類：

class WakeUp: 
    def __init__(self,date,time): 
     self.date = str(date) 
     self.time = str(time) 
     self.brush_teeth = brushteeth 
     . 
     . 

    def get_wakeup_activities(self): 
     return 'date: ' + self.date + 'time' + self.time. + 'brush_teeth', + self.brush_teeth

我打算避免冗長的打字，期望重構方法爲：

def get_wakeup_activities(self): 
     act_list =() 
     for attr in attrs: 
      act_list.append(attr) 
     return 'date: %s time:%s brush_teeth: %s' %tuple(act_list)

當該方法被調用時，輸出

date:2017-10-17 time:11:50:27 ...

或更多摘要：

def get_wakeup_activities(self): 

    wakeup_dict = {k:v for k, v in self.attrs} 
    return wakeup_dict

雖然調用命令：

today_wakeup = Wakeup 
today_wakeup.get_wakeup_activities()

輸出：

{date:2017-10-17, time:11:50:27,....}

側面說明：如果你打算爲簡潔（避免類型'self'一遍又一遍）你可以使用現代字符串格式來實現此目的，將字符串版本更改爲'return'date：{0.date} time：{0.time} brush_teeth：{0.brush_teeth}'。format（self）'仍然重複標題和名稱，但它是一些東西。 – ShadowRanger

一個實用的微調@ ShadowRanger –

class WakeUp: 
    def __init__(self,date,time, brushteeth): 
     self.date = str(date) 
     self.time = str(time) 
     self.brush_teeth = brushteeth 

    def get_wakeup_activities(self): 
     return self.__dict__ 

today_wakeup = WakeUp('today', '8am', 'YES!') 
print(today_wakeup.get_wakeup_activities())
