[PyQt] I want my GUI to change appearance based on what happens in a for-statement as it happens. Instead it changes after the whole for-statement ends.

[Kalish, David Price]

In my GUI I have a for-statement that opens a text file and changes the color of a QFrame depending on the first letter of each line in the file.  The relevent part of the code is attached as a text file, and so is the sample text file I've been using.

The raw_input lines were added so I could pause it and see when the color changes.  I expected it to change color when I had to raw_input, but instead it waits until the line of the text file to change color.  How do I make the QFrames change color as it goes through the file?

Thank you,
David
