Complete the Team class implementation. For the instance method get_win_percentage(), the formula is:
team_wins / (team_wins + team_losses)
Note: Use floating-point division.
Ex: If the input is:
Ravens
13
where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the
output is:
Congratulations, Team Ravens has a winning average!
In this lab work, you will implement a coffee shop example. In this coffee shop, everything must
progress as if it does in real life. It means that the program should ask a person for body
temperature in Celsius, and grant or reject access to a coffee shop. When a customer orders a
coffee, they have to choose a size such as Small, Medium, and Large then, depending on the
order, the price has to change. The price also has to change depending on the type of coffee.
For example, for coffees that are similar to espresso, you also need to take every shot of
espresso into account. The actual prices of the coffees depend on your imagination however,
they should be realistic.
Some hints:
• Focus on dividing your program into multiple functions.
• You can also return double or integer types of values from your functions, so use them if
you can.
• Don't just code a function every possible type of, and try to make it generic as much as
possible.
• Be creative. Fill the gaps using your…
What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)? Use a Monte Carlo Simulation and a frequency table to write a program that calculates this probability, where the number of people (x) in the simulated class is given by the user. The probability for a class of size 23, should be right around 50%.
PLEASE use the code outline given below to answer this question:
import mathimport random
# create and initialize frequency table:ft = []k = 0while(k < 365) : ft.append(0) k = k+1
# Allow the user to determine class size:print("Please type in how many people are in the class: ")x= int(input())
success = 0
# Simulate:c = 0while(c < 10000) : # Step 1: re-initialize birthday frequency table (it must be re-initialized for each play-through (why?): k = 0 while(k < 365) : ft[k] = 0 k = k+1 # Step 2: randomly get x birthdays and update frequency table: k = 0 while(k < x): # your code…

- 4. Write a program that computes the area of a circular region (the shaded area in the diagram) given the radii of the inner and the outer circles, rị and r, respectively. We compute the area of the circular region by subtracting the area of the inner circle from the area of the outer circle. Define a Circle class that has methods to compute the area and circumference. You set the circle's radius with the setRadius method or via a constructor.arrow_forwardYou are responsible for adding the appropriate testing code to your main. a.

The StudentTest class stores math and ELA test scores for a student. We will then extend this class in the HSStudent class, which will check the math and ELA scores to determine if the student has passed. Combined with service hours, the HSStudent class will also check to see if the student has qualified for graduation. Details for each class are outlined in the starter code for each class. In the StudentTester class, you will prompt the user for test scores and service hours, then use these to create a HSStudent object. After creating the object, print out the results.

There are three kinds of movies in the collection: dramas, comedies, and documentaries. The collector would like to keep track of each movie's title, the name of its director, and the year the movie was made. Some operations are to be implemented for all movies, and there will also be special operations for each of the three different kinds of movies. How would you design the class(es) to represent this system of movies? Your design should implement the concept of Overridingarrow_forward
