Modules in Python

You create functions in every file, sometimes the functions are used repeatedly in every different files. You always create a function and call it every time.

Example of set with “In”:- things_to_buy = {'milk','bread','biscuits','vegetables','juice','milk'} print(things_to_buy) if 'milk' in
