print (‘conexion ON’) while(response<200): response is a string (“something” in your debugging output). You are comparing it to an integer. In some implementations of Python, integers always compare “less than” strings, and it looks like that’s why the loop is getting skipped in your case. 3 solved I cannot pass of the first print

Here’s something you can try. It uses a collections.defaultdict or collections.Counter to count High, Med and Low for each product, then merges the results at the end. from collections import defaultdict, Counter product_issues = [ {“product”: “battery”, “High”: 0, “Med”: 1, “Low”: 0}, {“product”: “battery”, “High”: 1, “Med”: 0, “Low”: 0}, {“product”: “battery”, “High”: 1, … Read more
Your question is still ambiguous. Your example doesn’t have the first field Team_Name introduced in your header. So the index here is probably off by one, but I think you get the concept: #read lines of text file and split into words lines = [line.split() for line in open(“test.txt”, “r”)] #sort lines for different columns, … Read more

Often all frames are in the one file like this: http://www.ucigame.org/Gallery/images/char9.png You (as game developer) have to draw appropriate frame every 1/25 second (to get 25 FPS). Game libraries (like PyGame) are there to help you with that – mostly they use … Read more
