Body Mass Index
Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:
BMI = weight × 703 / height2
where weight is measured in pounds and height is measured in inches.
The file is in the format
name weightInKG heightInCM
You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch).
The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight.
Your output should look like
A person’s weight…
Range for loop should be used even the block code needs to access index.

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…

Distance Traveled The distance a vehicle travels can be calculated as follows: distance = speed time For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. The program should then use a loop to display the distance the vehicle has traveled for each hour of that time period. Here is an example of the output: What is the speed of the vehicle in mph? 40 How many hours has it traveled? 3 Hour Distance Traveled 40 80 3. 120 Iuput Validation: Do not accept a negative number for speed and do not accept any value less than 1 for time traveled.arrow_forwardWe use For loop instead of a while loop when we know exactly how many times you want to loop through a block of code.

Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph far a three-hour time period, it should display a report similar to the one chat follows: Hour Distance Traveled 1 90 2 100 3 150 Input Validation: Do not accept a negative number for speed and do not accept any value les than 1 for time traveled.arrow_forward
