[Tutor] cases with single if and an else clause

[Manprit Singh]

So...once again ...many many thanks to Dennis ....and Alan sir .

Today .it was something ..that made me to think...differently ..

Upto this ..point ...I was habitual of writing longer if else inside
functions ..but today's...mail of Dennis...has taught me so many things...

And...I am not a programmer ..python ...is just my hobby...just...to
say...I am glad...I am learning it day by day.
