Practice of Tuples in Python. It contains all the function that could be done with the help of tuple. There are basically only 2 main main functions of a tuple and that are counting and indexing. if i have defined a tuple as t1 and I use t1.count(45) then it search entire tuple and find how many times 45 is present. If I use t1.index(45) then it will give the index value of 45 like where exact 45 is present in tuple. Other this some basic functions are also present .
