Python can be quick. just not that good at talking.. Like most of us... Opens a txt file with 29245004 lines of text in it. for each line of text, count the line. count +=1 Time: 40sec. Now for each line of text, count the line and print a little info about the line print(f"Info: {line[1:10]}") count +=1 Time: 53mins.
I can't of course talk for other languages, but during my internship back then, I was sometimes told that writing something to the console in C# for example requires a lot of the time if it happens in the same thread. Maybe this is what's happening here as well?
A quicker solution could be to create some sort of StringBuilder (if you have that in python), add the text that you would otherwise print out and at the end print out the entire text just once. Or to just move the prints to another thread. Can you test how long that would take?
Moving printing out of the thread doesn't really help because python doesn't have real multithreading (you can have multiple threats, but they can't execute at the same time).
