write a program that takes as input a plain text file containing natural

language, and produces a list of each normalized type $($unique token$)$ and the

number of times it appears in the file, sorted from largest to smallest.

The user should be able to type:

myfile.txt $()$

And the results should be printed to the screen. E$.$g$.,$

$ python normalize$\_$text.py myfile.txt $--$lower $--$stem

should produce something like:

the $5000$

dog $1204$

ran $506$

$...$

and so on$.$ Options that the user can control must include: lowercasing, one of

either stemming or lemmatization, stopword removal, and at least one additional

option you added.In python and CANNOT use external libraries!!
