Review.

I tested all the four features and they are working.
Plus updated the .gitignore file.

@umangahuja1, it is a good start, but changes in lscorecard.py are not necessary (no need to put extra () ), so remove it and for changes in score.py, I will verify soon.

Yup I saw that, but to make sure all changes are done from 2 to 3, I used ide to convert it.

@umangahuja1, for py2 to py3, check which package is not compatible and change it accordingly like you have done it in score.py , I think I have already used packages which are also compatible with py3 in other scripts best way to check, run CrickFev in py3 env and see errors and if there is no error it also compatible with py3.

[umangahuja1]

Yup I ran and there are no errors. All 4 were running good.

[umangahuja1]

Have you reviewed this PR.

@umangahuja1, I had reviewed it and i got errors in score.py, correct, run and then send PR.
