You should certainly read more on regex. A first hint is that when you want to capture a pattern you need to enclose it in parentheses. e.g. (\d+). For this example though, the code you need is: match = re.match(r’C(\d+)([F|G])(\d+)\.PNG’, s) first_id = match.group(1) fg_class = match.group(2) second_id = match.group(3) 1 solved How to extract … Read more
a==14 is not a statement, it’s an expression. It produces a boolean result, that is discarded as soon as it is produced. It is a line that has absolutely no effect on the program. On the other hand, there is no === operator in python, that’s why your program fails in that case. Contrary to … Read more
You are missing -r command flag, so go again with pip install -r requirements.txt As it was before, pip just tries to get requirements.txt from remote store expecting it to be a package name. See pip help install Usage: pip install [options] <requirement specifier> [package-index-options]… pip install [options] -r <requirements file> [package-index-options]… … pip also … Read more
Generally it’s an awful way to write code, and does not guarantee that it will be any faster. Things which are simple and fast in one language can be complex and slow in another. You’re better off either learning how to write fast Python code or learning C++ directly than fighting with a translator and … Read more

the logic of the posted code is flawed, you set the turtle object at the beginning and it appears (as it should). but then you use an endless loop that update the object but there is nothing to update. so the code after the loop is never executed -> no shape will appear So doing … Read more
