1) Python supports the use of data files. In Python there are different modes that allow a user to create, write, append, read, and update date files. Table 1 shows the various file modes in Python.
Make a Python program that creates a user interface (menu) which allows the user to choose an option from the followings menu then perform the required task accordingly. The menu should have the following options:
1. Writing text to a file: Write the 6 to 8 lines of text into a file named "assignment2.txt". You can use special characters such as to separate lines.
2. Read Data from a file: reads (retrieve) the data from the file "assignment2.txt" and print it on the screen in the same format as it was input (i.e., same number of lines). Make sure
Table 1: Python File modes
Mode Description
'r' Opens a file for reading.
'w' Open a file for writing. If file does not exist, it creates a
new file. If file exists it truncates the file.
'a' Open a file in append mode. If file does not exist, it
creates a new file.
'+' Open a file for reading and writing (updating)
the file already exist and it is not empty, otherwise warn the user that the file doesn't exist or it is empty.
3. Search for string and calculate the number of occurrences: you should search for a certain word that you specify from the text. If the word doesn't exist, it should report to the user "the word doesn't exist" and asks the user to enter another word.
4. Quit the program: allows the user to quit the execution of the program.
