Qt Alignment in PyQt5

In PyQt5, Qt alignment is used to set the alignment of the widgets. In order to use the Qt alignment methods, we have to import Qt from the QtCore class. 

from PyQt5.QtCore import Qt

There are many methods in Qt alignment :
1. Qt.AlignLeft 
2. Qt.AlignRight 
3. Qt.AlignBottom 
4. Qt.AlignTop 
5. Qt.AlignCenter 
6. Qt.AlignHCenter 
7. Qt.AlignVCenter

Note: There are also some alignment methods like Qt.AlignJustify but they works in PyQt4 not in PyQt5. 

Code :
The code will show all these methods and helps in better understanding the differences.
