Python - import challenge - blackjack game - Day 23

if we directly import the module it will execute w/o users control..ie it will execute immediately after the import statement which is not intended..

here few changes are made to run the module from other code..ie by importing it and calling the functionality whenever needed

we can make use of the __name__ to do this

import blackjacktest1
print (__name__)
blackjacktest1.play()
