python - PyQt application and infinite loop - 


  डीईफ़ मुख्य (): ऐप = QtGui.QApplication (sys.argv) GUI = GUIClass () gui.showUI () App.exec_ () जबकि true: if win32api.GetAsyncKeyState (win32con.VK_SHIFT): प्रिंट (True) अगर __name__ == '__main__': मुख्य ()

ऐप के बाद कोड Exec_ () चल नहीं रहा है अनगिनत लूप कैसे करें और मेरा पाय्युटी एप्लीकेशन चलाएं?

धन्यवाद।

pyqt अपने स्वयं के (अनन्त) ईवेंट लूप के साथ आता है ताकि आपको अपना खुद का निर्माण न करना पड़े। app.exec _ () इस पाश में प्रवेश करता है, यही कारण है कि आप निष्पादित करने के बाद कोड नहीं देखते हैं। QTimer के उपयोग का उदाहरण:

में मुख्य () से पहले exec_ ( ) : 

  def timout (): यदि win32api.GetAsyncKeyState (win32con.VK_SHIFT): प्रिंट (True) टाइमर = QtCore.QTimer (स्वयं) timer.timeout.connect (टाइमआउट ) टाइमर.प्रारंभ (100)

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks
