Question
Transcribed Image Text:The pretty_print_dollars Function
In TODO 2, you will implement the pretty_print_dollars function. The function has a single number parameter that is expected to be int or float. The output of the pretty_print_dollars function is the
same number converted to str nicely formatted as a dollar amount with two decimals for cents as shown below:
pretty_print_dollars (1000.e) -> '1,000ドル.00'
pretty_print_dollars (5.99)->'5ドル.99'
pretty_print_dollars (547475874) ->'547,475,874ドル.00'
pretty_print dollars(-84989) ->-84,989ドル.00'
pretty_printdollars (999.50) -> 999ドル.50
You are encouraged to validate your implementation by placing several calls to the pretty_print_dollars into the if _name__ == '__main__ block in task2.py as shown below:
if __name__ '___main___':
print (pretty_print_dollars (1000.0))
print (pretty_print_dollars (5.99))
print (pretty_print_dollars (547475874))
print (pretty_print_dollars (-84989))
print (pretty_print_dollars (999.50))
The expected output of running the task2.py file would then be:
(p2-env) -/ppp-iteration-conditionals-strings $ python task2.py
1,000ドル.00
5ドル.99
547,475,874ドル.00
-84,989ドル.00
999ドル.50
Transcribed Image Text:def pretty_print_dollars(number):
str "${:0,.2f}" .format(number)
return str

- In C++ only Create a function called MultyDieRoll. It should take in an integer and run the function DieRoll that number of times, printing out each result to the console. So for instance, if you pass in a 7, it should output 7 random numbers; if you pass in a 21, it should output 21 random numbers.arrow_forwardOne lap around a standard high-school running track is exactly 0.25 miles. Define a function named laps_to_miles that takes a number of laps as a parameter, and returns the number of miles. Then, write a main program that takes a number of laps as an input, calls function laps_to_miles() to calculate the number of miles, and outputs the number of miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f'{your_value:.2f}') Ex: If the input is: 7.6 the output is: 1.90 Ex: If the input is: 2.2 the output is: 0.55 The program must define and call the following function: def laps_to_miles (user_laps) 461710.3116374.qx3zqy7 LAB ACTIVITY 7.8.1: LAB: Track laps to miles 1 # Define your function here 2 3 if __name__ 4 main.py == '__main__': #Type your code here.

This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.arrow_forward
- This question has 2 parts, in part A you will write a function and part B need to implement the function Part A - Write a function called getDistance. This function will have 2 parameters: first is the speed of the object in miles per hour the second is time traveled in hours. The function will return the distance traveld by multiplying the speed by the time passed by parameter. Part B will be a small program that will input the speed and time traveled by 2 vehicles. It will then print which vehicle traveld the furthest and must utilize the function written in part A appropriately. Complete the starter file below (copy and paste into your answer). #write your function here def main(): vehicle1_speed = int(input("Enter the speed of vehicle 1: ")) vehicle1_time = int(input("Enter the time vehicle 1 has traveled: ")) vehicle2_speed = int(input("Enter the speed of vehicle 2: ")) vehicle2_time = int(input("Enter the time vehicle 2 has traveled: "))...arrow_forward2. Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: Nonearrow_forwardIn C++ i need the fill in the functions that will complete this code for the program to work.arrow_forward

- Write a set of functions that calculate the cost of movie tickets for a family. These functions should use a pass-by-reference variable that accesses the double running_total variable in main(). Using a loop, keep displaying the ticket prices for each age group: Something like: Model Hall Movie Ticket Box Office Under Age 3 (free) Ages 3-11 (10ドル.25) Ages 12-54 (15ドル.50) Age 55 or older (12ドル) If 4 tickets are purchased (not counting under age 3) then 20% discount Within the loop: Keep asking the user to input the moviegoer age and to enter a zero for the age when they are finished inputting all the family members. Also, within the loop: Keep a running_total that is output to the screenafter each age has been entered. This running_total should be accessed through the functions using apass-by-reference variable. Finally, after the looping is done: Calculate the total cost, including a 7.5% sales tax, and output it to the screen.arrow_forwardWrite a function named product that takes two int parameters and returns the product of those two integers. Here is an example: int n = product(7, 5); // n is 35 We are providing a test framework that, if you wish, you may use with a compiler to test your function. What you will submit as your answer to this problem is only the product function. Do not submit things like the #include lines or a main routine. If we take the code you write in the space below and insert it into the program, the resulting program must build without compilation errors (mere warnings are allowed). You do not need to write comments in the code; we will not look at any comments. Here is the test framework that you may copy and paste into a C++ source file. For your own testing purposes, you might add additional tests in the main routine, although you won't be turning them in, of course. #include <iostream> #include <cassert> using namespace std; // SUBMIT AS YOUR ANSWER ONLY THE CODE BETWEEN THIS...arrow_forwardProblem 2: Write a function called digitMatch. The function has three integer parameters first , second and third that are positive and have the same number of digits. It returns the number of positions where their digits match. For example, if the function was applied to 17345, 97813 and 17313 it would return 1 because only the 2nd digits match. If parameters have illegal values your function can operate however you choose. For example, a program that uses the function follows. int main() { cout <« digitMatch(168, 567, 767) « endl; // prints 1 cout <« digitMatch(143, 243, 343) « endl; // prints 2 return 0; }arrow_forward
