Advertisements I have a text file as a list, each line is an item in the list. This list contains multiple start tag and end tag (but otherwise not structured) and I must iterate through the file processing data between the start and end tags. Due to potential errors in the file, I must ignore… Read More Python loop through list, enumerate, and start and end at specific index, but do not modify the index

Advertisements Consider the code below. I am trying to subclass the builtin enumerate so that it prints a line for every turn of the for loop. The code seems to be working, which is surprising, because I have never called super().__init__(x). So, what is happening here? Who is initializing the base class enumerate the right… Read More subclassing the builtin enumerate in python

Advertisements Question: Take the following: def a(the_enumerate: enumerate): print("index: " + str(the_enumerate[0]), character: " + the_enumerate[1]) map(a, enumerate("test")) Is there a way of naming the index and the current element (character) in a better way than: index: int = the_enumerate[0] character: int = the_enumerate[1] Perhaps it would be something like this: def a(the_enumerate: enumerate(index: int,… Read More Python – naming parameters from enumerate
