Step by step
Solved in 2 steps
- Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return. Code:from Contact import Contactimport pickledef load_contacts():""" Unpickle the data on mydata.dat and save it to a dictionaryReturn an empty dictionary if the file doesn't exist """try:with open("mydata.dat", 'rb') as file:return…PHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…### QUESTION FIVE ### def select_lines_from_file(filename, query): pass
- Completion 2: Rectangle - the contains method The following function aims to check if a rectangle contains a point. Simplify it in lab file Rectangle.java by using calls to InOrder. Note this isn't the most efficient strategy in terms of the number of operations, but your code should be much more readable that the original.File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]
- Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function.

- 5. select_lines_from_file In this function, we will open a file for reading, look at each line in the file, and return a list of the lines in the file that contain a specified query string. We do not need to change the lines in the file in any way, just put them in a list and return that list. Don't worry about case -- this function is case-insensitive. If we have the following text in a file called final_sample.txt: it was the best of times it was the worst of times time keeps on slippin into the future this sentence does not contain that particular word also this one doesn't contain it either Then a sample call should look like: | >>> select_lines_from_file("final_sample.txt", "time") ['it was the best of times\n', 'it was the worst of times\n', 'time keeps on slippin into the future\n']Programming: If loops & Input From Data File.
