F strings used

[ashishrawat0]

Well, I have changed the use of fstring in some of the places. Please review the PR

I will change the other print commands also if this PR gets Approved

Hey @ashishrawat0, thanks for your work. I don't want to discourage your contribution, but there's already an open PR about this (#4324). It has currently many conflicts, because as mentioned in the original issue (#4307), f-strings need Python 3.6+ and we still support 3.5.

Hi, @elacuesta thanks for letting me know I just wanted to know that can we use .format() because python 3.5 supports it and thanks for replying I just wanted to contribute to open-source projects.

@ashishrawat0 Switching to format now to switch to f-strings in a few months (3.5 reaches end of life soon) seems a bit pointless to me. I think it might be better to close this pull request, and just leave #4324 open for the eventual switch to f-strings.
