You are tasked with implementing a text encryption and address book management program. The program should perform the following tasks: Text Encryption: Create a function named count_char that takes the name of a text file as input. This function should: a. Print on the screen the count of unique characters in the text file using a set. b. Return a dictionary containing the number of duplications of each character in the text file. Create a function named encrypt_text that takes one argument: the dictionary containing character counts from the previous function. This function should: a. Read the text file. b. Encrypt the text using a simple encryption algorithm. For each character, replace it with the character corresponding to its frequency in the dictionary (e.g., the most frequent character is replaced with ' A ', the second most frequent character with ' B ', and so on). c. Store or write the encrypted text in a new file. Address Book Management: 3. Implement a simple address book management system using a dictionary. The dictionary should store the names (keys) and phone numbers (values) of contacts. 4. Create functions for the following address book functionalities: add_contact(name, phone_number): Adds a new contact to the address book. search_contact(address_book, name): Searches for a contact by name and displays their phone number if found. If the contact is not found, inform the user. delete_contact(address_book, name): Deletes a contact by name if found. Ensure that your program provides a menu-based system for user interaction and handles various scenarios as below: address_book ={} if choice ="1": print("Selected: Encrypt a text file") # Implement the function calls for text encryption here elif choice = "2": print("Selected: Address Book Management") # Implement the function calls for address book management here elif choice ==" 3 ": print("Goodbye!") break Python You are tasked with implementing a text encryption and address book management program.
