Wannan koyarwar tana mai da hankali ne kan koyar da amfani da tsarin QT ta amfani da Python a matsayin yaren shirye-shirye, saboda wannan zamu iya amfani da PySide da PyQt, amma a cikin wannan koyarwar zamuyi amfani da PySide saboda marubucin wannan koyarwar ya fi son LGPL PySide lasisi mafi kyau. fiye da GPL ko PyQt Kasuwanci.

Na farko ... Menene Python?

A cewar Wikipedia:

"Python babban yare ne mai fassarar shirye-shirye wanda falsafar sa ke karfafa rubutu mai tsafta kuma yana son lambar da za'a iya karantawa."
