Problem $1$: File Processor

Objective: Create a Python CLI script that processes a text file based on user input.

Requirements:

File Path Argument $($file$)$: A string argument for the path to the text file to be processed. Operation

Argument $(--$operation$)$: A choice argument to specify the type of operation to perform on the file.

Options should include:

line$-$count $($number of lines$)$

word$-$count $($number of words$)$

uppercase $($convert all text to uppercase and display$)$

contains $($used with $--$word, check if file contains the word$)$

Word Argument $(--$word$)$: A string argument that specifies a word to find in the file. This should only be

required if the find operation is selected.

Displays error message for file not found.

You can create a file with the following content for testing.

Python is an interpreted, high$-$level and general$-$purpose programming

language.

Python's design philosophy emphasizes code readability with its notable

use of significant whitespace.

Its language constructs and object$-$oriented approach aim to help

programmers write clear, logical code for small and large$-$scale projects.

Python is dynamically typed and garbage$-$collected. It supports multiple

programming paradigms, including structured $($particularly$,$ procedural$),$

object$-$oriented, and functional programming.

Python is often described as a "batteries included" language due to its

comprehensive standard library.
