Objectives: practice with math, while-loops, sentinels, input validation, functionsStarting with the provided file circles.py, write a program that uses functions to computethe area and circumference of a circle of a user-specified radius.The program consists of a main () function and two other functions, as follows:main (): Asks the user for the radius of a circle (floating point number). If the user enters aradius of zero, the program prints “Goodbye!" and ends. If the user enters a negative radius,the program prints “Invalid radius!", and asks again for a radius, and keeps asking until theuser enters zero or a positive number. If the user enters a positive number, the program callsthe two other functions and prints: A circle of radius R has circumference C and area A.(where R is the radius number, C is the calculated circumference, and A is the calculatedarea.) After printing the circumference and area, the program asks again for a new radius.[20 pts]circumference (r) : Takes a radius r as a parameter and computes and returns thecircumference of the circle, using the math formula 2nr (Note: this function does notprint anything.) [15 pts]area (r): Takes a radius r as a parameter and computes and returns the area of the circle,using the math formula rr? (Note: this function does not print anything.) [15 pts]The provided starter program imports Python's math module, which provides an accuratevalue for pi in the pre-defined variable math.pi.

Write a program that calculates the balance of a checking account at the end of a three- month period. It should ask the user for the starting balance. Then a loop (for loop is recommended) should iterate once for every month in the period, performing the followi 1. Ask the user for the total amount deposited into the account during that month. Do n accept negative number. This deposit should be added to the current balance to make current balance is up to date. 2. Ask the user for the total amount withdrawn from the account during that month. Do accept negative amount or amount greater than the current balance. The withdrawal amount should be subtracted from current balance, so current balance is up to date. 3. Update the total deposit. 4. Update the total withdrawal After the last iteration, the program should display the following information: 1. starting balance at the beginning of the three-month 2. total deposits/withdrawals made during the three-month period 3. final balance…
Here are three versions of a code fragment located inside a function: Version A for Row in range(10): for Column in range(5): DoSomethingInteresting(Row,Column) return Version B for Row in range(10): for Column in range(5): DoSomethingInteresting(Row,Column) return Version C for Row in range(10): for Column in range(5): DoSomethingInteresting(Row,Column) return How many times do each of the versions call the DoSomethingInteresting function? Write a sentence or two explaining which version is the "correct" version
The prompt asks: Write a function that calculates the amount of money a person would earn over a period of years if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should ask the user for the number of years and call the function which will return the total money earned in dollars and cents, not pennies. Assume there are 365 days in a year. function totalEarned(years) { } var yearsWorked = parseInt(prompt('How many years will you work for pennies a day? ')); alert('Over a total of ' + yearsWorked + ', you will have earned $' + totalEarned(yearsWorked));
write python code for functions:
C programming Only
Calling a function and defining a function mean the same thing True or False
The parameters passed to function are .called formal parameters True O Fales O
PLEASE COMMENT ALL CODE Create a python program that checks whether a number is even or odd. Sample run: Even or Odd Checker Enter an integer: 33 This is an odd number. Specifications Store the code that gets user input and displays output in the main function. Store the code that checks whether the number is even or odd in a separate function. validate the use inputs, only integers accepted, give the user an option to enter again, ask the user if wants to try again.
A function may have any number of return statements each returning different values.

Local variables are known only to the function in which they are declared. Local variables are invisible outside the function in which they are declared. Whether True or False 11. It is possible for any function to return numerous values. Any function type may return multiple values. That's true, right?
