why the same code, the computer in his home run can be interlaced show different color, unit computer run does not display the color, the font display (operating system, the same home is py3.7, unit is 3.8 at the beginning of computer

Do you have a problem solved, I have recently encountered the same problem with you, I am using python3.8.2 version, reference books are HongJinKui "Python GUI design tkinter novice programming", the book examples in the application of 18-3 quarter ch18_6. Py code that can run on my computer, but is not alternating color, at first I thought it was my code type is wrong, then check line by line, completely like the book, but is not alternating colors, my kao down other people's code to run from the Internet is also the same result, don't know is why

# ch18_6. Py

For the state in stateCity. Keys () :
If the rowCount % 2==1:
Tree. Insert (" ", the index=END, text=the state that values=stateCity [state])
The else:

I can try Python3.6.5 3.7.6 and 3.8.2 can't

CodePudding user response:

Do you solved? I also found this problem, the 3.6 stable color, 3.7 basic will not change color, see the equipment
