$1.$ Write a function in Python to count the words "this" and "these" present in a text file

"article.txt$".[$Note that the words "this" and "these" are complete words$]$

$2.$ Aditi has used a text editing software to type some text. After saving the article as

WORDS.TXT$,$ she realized that she has wrongly typed alphabet J in place of alphabet

I everywhere in the article. Write a function definition for JTOI$()$ in Python that

would display the corrected version of entire content of the file WORDS.TXT with

all the alphabets $"$J$"$ to be displayed as an alphabet "I" on screen.

Note: Assuming that WORD.TXT does not contain any J alphabet otherwise.

Example:

If Aditi has stored the following content in the file WORDS.TXT:

WELL, THJS JS A WORD BY JTSELF. YOU COULD STRETCH THJS TO BE A

SENTENCE

The function JTOI$()$ should display the following content:

WELL, THIS IS A WORD BY ITSELF. YOU COULD STRETCH THIS TO BE A

SENTENCE

You can use read$()$ method which will read each character in the file in the loop if

you want to operate on each characters.

$3.$ Write a function lines$\_$count$()$ that reads lines from a text file named 'zen.txt$\text{'}$ and

displays the lines that begin with any vowel. Also, write that content on a new text

file. Assume the file contains the following text and already exists on the computer's

disk:

Beautiful is better than ugly.

Explicit is better than implicit.

Simple is better than complex.

Complex is better than complicated.

The lines$\_$count$()$ function should display the output as:

Explicit is better than implicit.

$4.$ Assume that a file named 'feedback.txt$\text{'}$ contains student feedback in the following

format:

Positive: Saksham improved grades, more confident now.

Negative: Arav needs better time management for coursework.

Negative: Samar should work on communication in group activities.

Negative: Soham could benefit from asking more questions in class.

Positive: Sakshi excels academically, a great team player.

Write a Python function named feedback$\_$analysis$()$ to calculate and display the

following information:

Total feedbacks stored in the file.

Count of positive feedbacks.

Count of negative feedbacks

You can use startswith$()$ method to check the first word of each line while matching.
