python" You have a circular (cylindrical) pool with a radius of 9 feet and you want toknow how much water will be required to fill it to different depths. You remember that thevolume of a cylinder is Ttrd, where r is its radius and d is its depth.Write a function named "pool_volume" that takes a float as an input (parameter) whichrepresents the depth to fill the pool in feet and returns the number of cubic feet neededto fill the pool to that depth.

In Python Assume that you have a data structure of the following: A list of hockey players. Each hockey player is a list that includes their Rank (int), Name (String), Team (String), Age (int), Goals (int), Assists (int), Points (int) in that order. Write a function called most_goals that takes in the list of hockey players and returns the name of the player with the most goals. For example: Test Result print(most_goals(nhl_list1)) David Pastrnak
Create a Python function “PolarToCartesian” that allows the user to convert from polar form to Cartesian form and vice versa. The function should print the result of conversion.Write a main code in which the user should choose the conversion he/she wants, then he/she should enter the number (real part and imaginary part if the input number is Cartesian, magnitude and phase if the input number is Polar)You can import ‘numpy’ for trigonometric functions and square root calculations, and you can import ‘math’ for math.pi number.
I can't seem to figure this out.. for python You have a business that cleans floors in commercial space and offices. You charge customers $0.45 per square yard, and some customers require multiple cleanings every month. You need two custom functions for your business. The first function takes a floor's length and width in feet and returns the area in square yards. The second void function takes the area, charge per square yard, and number of monthly cleanings as arguments and prints the cleaning cost. This latter function uses selection logic to print different output for single and multiple monthly cleanings (see Sample Outputs). Use a properly named constant for the charge per square yard, too.
Write in Python Write a function named max that accepts two float values as arguments and returns the value that is the greater of the two. For example, if 7.2 and 12.1 are passed as arguments to the function, the function should return 12.1. Use the function in a program that prompts the user to enter two float values. The program should display the value that is the greater of the two.
3. Write a PYTHON function called midpoint quad.py with signature def midpoint quad (func, a, b, N) #quad = midpoint quad ( func, a, b, N) # comments return quad where func indicates the name of a function, a and b are the lower and upper limits of integration, and N is the number of points, not the number of intervals. Test your midpointquad routine by computing f2rdx = 1. Even if you use only one interval (i.e. N = 2) you should get the exact answer because the midpoint rule integrates linear functions exactly. Use your midpoint routine to estimate the integral of the Runge function, f(x) = 1/(1+x2), over the interval [-5, 5]. The exact answer is 2 arctan (5). Fill in the following table, using scientific notation for the error values so you can see the pattern. Midpoint Result Error N h 11 1.0 101 0.1 1001 0.01 10001 0.001 Estimate the order of accuracy (an integer power of h) by examining the behaviour of the error when h is divided by 10. (In previous problems, we have estimated…
Writing Functions that Return a Value Summary In this lab, you complete a partially written Python program that includes a function that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, -, *, or / ). The two numbers and the operator are passed to the function where the appropriate arithmetic operation is performed. The result is then returned to where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3 * 4 = 12 The source code file provided for this lab includes the necessary input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Write the Python statements as indicated by the comments. Execute the program.
Design a function called intdiv() which takes a dividend and a divisor as parameters and returns the result and remainder (2 integers) as a tuple. E.G. given 9/2 equals 4 remainder 1:9 is the dividend, 2 is the divisor (parameters), 4 is the result and 1 is the remainder (values returned as a tuple).Write program statements which test this function by calling it twice with different parameters, and printing the returned values each time.
Python Suppose scDict maps names to test scores. Print each name/score on a separate line Write a function calcStats that calculates and RETURNS the average, highest, and lowest of the scores. The function should NOT print anything. Ex: scDict ={“Joe”:70, “Bob”:90, “Sue”: 95} Output: Joe 70Bob 90Sue 95Average: 85High Score: 95Low Score: 703. Ask the user to enter a name and a score, and put that entry into the scDict. Ask the user to enter a name to delete and remove that entry Check to see if the dictionary contains a key “Mary” and print “YES” if it does. 6. Print the dictionary, sorted by name
Python Help Write a function rectangle_area(length, width)Write a function rectangle_perimeter(length, width)Write a function circle_area(radius)Write a function circle_circumference(radius)Write a main function that asks the user to choose whether to find the area of a rectangle, the perimeter of a rectangle, the area of a circle or the circumference of a circle. If the user chooses to find the area of a circle use circle_area function, if the user chooses to find the area of a rectangle use rectangle_area function and so on.
