Im working on the rental class now .如何調用從另一個類(Python)的特定屬性
The rental class is needed for the rental object which has attributes from the other classes
我試圖用super.init
初始化其他屬性這是否正確,請指教。使用python 3.5

不,您不需要始終進行初始化。一個類由super.init初始化一次。如果您需要從一個類訪問另一個類的屬性,可以通過使用(self。「attribute」)在主線程上使用它們。正如您在Python中所瞭解的,每個類都在單獨的線程上工作。所以基本上你需要在主線程中提供該屬性,然後調用它。
例如,這裏是我寫的多線程代碼片段。
class workerThread(QThread):
signal = pyqtSignal(str)
def __init__(self):
super().__init__()
self.abort = False
@pyqtSlot()
def run(self):
#print("yeah yeah ")
time.sleep(0.1)
app.processEvents()
self.signal.emit('Done')
def __del__(self):
#print("okay okay")
self.abort = True
self.wait()
class General(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def saveClicked(self):
try:
tex=[]
for edit in self.lineedits:
tex.append(str(edit.text()))
if tex[0] and tex[1] and tex[2]:
if ('@gmail.com' in str(tex[1])) or ('@yahoo.com' in str(tex[1])) or ('@' in str(tex[1])):
contact=str(tex[2])
if self.validContact(contact):
self.workerthread = workerThread()
self.workerthread.signal.connect(self.savesuccess)
self.workerthread.start()
else:
self.workerthread = workerThread()
self.workerthread.signal.connect(self.errorcontactmsg)
self.workerthread.start()
else:
self.workerthread = workerThread()
self.workerthread.signal.connect(self.erroremailmsg)
self.workerthread.start()
else:
self.workerthread = workerThread()
self.workerthread.signal.connect(self.errornormmsg)
self.workerthread.start()
except:
self.workerthread = workerThread()
self.workerthread.signal.connect(self.crashingmsg)
self.workerthread.start()
請參閱此鏈接完整的代碼有一個想法 - Link
或者即使你只是想初始化,然後,
class Tetrominoe(object):
NoShape = 0
class Shape(object):
def __init__(self):
self.coords = [[0,0] for i in range(4)]
self.pieceShape = Tetrominoe.NoShape
self.setShape(Tetrominoe.NoShape)
但使用自調用一類的DEF屬性在另一種情況下,更好的選擇是通過「自我」在主線程上附加該屬性,然後在任何類中訪問它。
相當新的Python,但希望這有助於。
通過這個 - How would I access variables from one class to another?它會更有幫助。
