It is so confusing

Question

I do not know what does "/t" in my code mean. On Saturday, I made the code for erasing extra space between words. For example, if you put in"a b c", the output will transforms into a b c". On Saturday, the code worked. However, I have just played around it and it no produces the same output like 2 days ago. I do not know what is going with my code.

Answer 1

/t means tab, but I don't see it right now in your code. I've commented the line with print(lis) and assigned end to empty string and it works.
