@Sahil...well,there is no need to define your variable word or any other variables in Python prior to using it ,like in other languages..eg: int a in other languages in Python just a is enough & you could store anything in a like int, float ,string

When we write like this:- "for i in range (9):" , "i" variable is defined instantly.

There are 2 things which explain your case and also depict how python is awesome 1. word in your case is a reference variable which gets the reference of the elements of the list one by one iteratively 2. Python follows dynamic type casting that's the reason you do not need to give datatypes while assigning the variable.
