Task

"""

Write a program that receives from the user:
1. Path to Text File (String)
2. Name of one of the actions: rev, sort or last (string)

The file whose path is passed as an argument contains rows of word sequences in small English letters separated by a single space.

Depending on the user-recorded action the program performs:
• sort - The program prints all words in a file that has been transferred as a sorted alphabetical list, without duplicates.
• rev - The program prints the characters in each line of the file in the reverse order, that is, from beginning to end.
• last - The program receives from the user another parameter which is an integer (n), and prints the last n lines in the file (assume that the number is positive and also less than or equal to the number of lines in the file).

An example of a program input and lecture file
A file called sampleFile.txt:

i believe i can fly i believe i can touch the sky
I think about it every night and day spread my wings and fly away

Run the program on the sampleFile.txt file:

>>> Enter a file path: c:\sampleFile.txt	
>>> Enter a task: sort
['about', 'and', 'away', 'believe', 'can', 'day', 'every', 'fly', 'i', 'it', 'my', 'night', 'sky', 'spread', 'the', 'think', 'touch', 'wings']

>>> Enter a file path: c:\sampleFile.txt
>>> Enter a task: rev
yks eht hcuot nac i eveileb i ylf nac i eveileb i
yawa ylf dna sgniw ym daerps yad dna thgin yreve ti tuoba kniht i

>>> Enter a file path: c:\sampleFile.txt
>>> Enter a task: last
>>> Enter a number: 1
i think about it every night and day spread my wings and fly away
