Update mergesort.py (#2563) 
* Update mergesort.py

1) Updating the merge sort in python as the previous implementation was modifying the input array
2) divided the division part and conquer part of the merge sort algorithm as 2 functions namely mergeSort and merge.
3) function mergeSort divides the function into halves i.e the purpose of the function will be to divide the array
4) function merge will merge 2 halves into a sorted array
5)Added random test cases using shuffle as suggested by @dhruvmanila
6 The time and space complexity of the previous and my version remains the same. i.e (n log(n) time and n log(n) space
7) changed variables as per the python case as required and suggested by @dhruvmanila
8) Updated function names as suggested by @dhurvmanila

* Update mergesort.py

Added in few more test cases 
added type hints for the functions and parameters as suggested by @dhruvmanila
formatted the code using Auto Pep8

* Update mergesort.py

update and added new testcases
