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…

- A Personal Fitness Tracker is a wearable device that tracks your physical activity, calories burned, heart rate, sleeping patterns, and so on. One common physical activity that most of these devices track is the number of steps you take each day. The steps.txt file contains the number of steps a person has taken each day for a year. There are 365 lines in the file, and each line contains the number of steps taken during a day. (The first line is the number of steps taken on January 1st, the second line is the number of steps taken on January 2nd, and so forth.) Write a program that reads the file, then displays the average number of steps taken for each month. (The data is from a year that was not a leap year, so February has 28 days.) You don't need to see the file , Just write a code using the "file" like this def main(): with open("steps.txt", "r") as file:arrow_forwardSubmission: Combine the code files for Q1 and Q2 as a zip file and submit in Moodle Question 1: Write a Program that to enter Student Name, Grade and print it to the screen with below requirements . . . .

In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number.

World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.) Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009.

- Any loop statement can be used to traverse an array. True or Falsearrow_forwardTranscribed Image Text In this assignment, you will design a program in which you will ask the user to enter a number and use a while loop to see if the number entered by the user is a palindrome number or not. A palindrome number is a number which remains the same, even when the digits are reversed. For example: 121 is a palindrome number. 277 is not a palindrome number. Lab Procedure: 1. Prior starting of the work consider how to design the while loop: a. What would be the loop condition? b. What would be the stopping criteria? 2. Determine how to extract each digit. What are the variables and where to initialize the variables. 3. Test the application by hand-calculating several values and use the same values to validate the operationarrow_forwardPY THON Open file.txt from same folder and extract all the Names and number next to the name and sort them from highest number to lowest number.
