Question
Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies.
Ex: If the input is:
0
or less, the output is:
no change
Ex: If the input is:
45
the output is:
1 quarter 2 dimes
Your program must define and call the following function. The function exact_change() should return num_dollars, num_quarters, num_dimes, num_nickels, and num_pennies.
def exact_change(user_total)
Transcribed Image Text:```python
# Define your function here
if __name__ == '__main__':
input_val = int(input())
num_dollars, num_quarters, num_dimes, num_nickels, num_pennies = exact_change(input_val)
# Type your code here.
```
This script is written in Python. It begins by defining a function header placeholder with a comment. When executed, the script checks if it is running as the main program (`if __name__ == '__main__':`).
1. **Input Prompt**: It prompts the user for input and converts this input into an integer with `input_val = int(input())`.
2. **Function Call and Unpacking**: The script seems to call a function named `exact_change`, passing `input_val` as an argument. This function is expected to return multiple values that are unpacked into `num_dollars`, `num_quarters`, `num_dimes`, `num_nickels`, and `num_pennies`.
3. **Comment Placeholder**: The comment `# Type your code here.` suggests a placeholder for additional code to be added, likely to display or use the variables obtained from the `exact_change` function.

- Write a program that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage. Sample input and output is shown below. How many exercises to input? 3 Score received for exercise 1: 10 Total points possible for exercise 1: 10 Score received for exercise 2: 7 Total points possible for exercise 2: 12 Score received for exercise 3: 5 Total points possible for exercise 3: 8 Your total is 22 out of 30, or 73.33%.arrow_forwardWrite a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text. Ex: If the input is: Hello there Hey done then the output is: ereht olleH yeH 382800 2462264gayarrow_forwardThis program inputs the names of 5 students and the (integer) grades they earned in 3 tests. It then outputs the average grade for each student. It also outputs the highest grade earned in each test and the average of all grades in each test. Your output should look like this: Mary's average grade was 78.8% Harry's average grade was 67.7% etc... : : In test 1 the highest grade was 93% and the average was 89.2% In test 2........etc Your main method should be modular. Write a method that inputs the 5 names into an array (one dimensional), and returns this array to the main Write a method that inputs the 15 (integer) test grades into a (two-dimensional) array, and returns this array to the main Write a method that calculates the students averages and stores them in an array, and returns this array to the main Write a method that calculates the average grade for each test and stores them in an array, and returns this array to the main Write a method that determines the highest grade…arrow_forward

End each line with a newline. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is: 0 or less than 0, the output is: no change Ex: If the input is: 45 the output is: 1 quarter 2 dimesarrow_forwardDriving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f' % your_value) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. Note: This is a lab from a previous chapter that now requires the use of a function.arrow_forward
- Write a program that asks the user to enter a number of seconds and works as follows: There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should convert the number of seconds to minutes and seconds. There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should convert the number of seconds to hours, minutes, and seconds. There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should convert the number of seconds to days, hours, minutes, and seconds.arrow_forwardIn Coral Programing!! Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. Ex: If the input is -15 30, the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in 20 5, the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.arrow_forwardWrite a program that computes taxes for the following schedule.
