self.label_5.setStyleSheet("QLabel { background-color : white; color : blue; }")
self.label_6.setStyleSheet("QLabel { background-color : white; color : blue; }")
self.label_7.setStyleSheet("QLabel { background-color : white; color : blue; }")
self.label_8.setStyleSheet("QLabel { background-color : white; color : blue; }")

I tried to do the long code above using the gun as below
for i in range(5,9):
self.label_i.setStyleSheet("QLabel { background-color : white; color : blue; }")
As you can see, the syntax error appears because you put i in the variable name.
How can we reduce the length of code at the top by using the phalanx?
python
According to the standard, it should be like getting a list of children from the parent widget and repeating it.
The code doesn't seem to distinguish the source code that people understand from the binary code that computers understand.
Label_i can be understood by people, but there is no such thing as label_i when the source code is compiled.
Of course, Python is an interpreter language, so reflection is easy.
getattr(self, 'label_5') #label_5 field
for i in range(5, 8):
getattr(self, 'label_{}'.format(i))
You can do it with.
Next time you write a similar code, I recommend you to use the list.
