Toll roads have different fees based on the time of day and on weekends.
1. Write a function calc_toll() that has three parameters: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The function returns the correct toll fee (float), based on the chart below.
Weekday Tolls
Before 7:00 am ($1.15)
7:00 am to 9:59 am ($2.95)
10:00 am to 2:59 pm ($1.90)
3:00 pm to 7:59 pm ($3.95)
Starting 8:00 pm ($1.40)
Weekend Tolls
Before 7:00 am ($1.05)
7:00 am to 7:59 pm ($2.15)
Starting 8:00 pm ($1.10)
Ex: The function calls below, with the given arguments, will return the following toll fees:
calc_toll(8, True, False) returns 2.95calc_toll(1, False, False) returns 1.90calc_toll(3, False, True) returns 2.15calc_toll(5, True, True) returns 1.05

- Create a program in Python, called TA_Calculator, that uses a function to calculates the area of a triangle given the base and height measurements. Use the below function to do your calculation. The program should receive the base and the height from the user. Once the user enter a base greater than the height the program should give the user another attempt to enter a base and a height. The program only give the user three attempts to enter the correct base and height on the third attempt the program should display the below message: “You have exhausted your 3 attempts please try again later” If the user enter a base less than height, the program should display the correct triangle area using the given function. Hint: You should use a function, a loop, an if statement, a sentinel value,arrow_forwardDo not use global variables for this assignment Choose descriptive variable names in all programs. Currency format. There should be no space between the $ sign and the first digit. In python, Write a program that uses a custom function named as you wish and the main function. In main, prompt the user for a first name and an integer less than 10 and then execute the custom function with these two inputs as arguments. The custom function should output one line displaying the name as many times as specified by the integer, separating each repetition of the name with a space.arrow_forwardCreate a list of 10 numbers. Iterate through the list and store the highest and second highest numbers into max1 and max2 variables. Finally display max1 and max2. You are not allowed to use any built-in functions. Do this by using pythone.arrow_forward
- The formula for converting a temperature from Fahrenheit to Celsius is C=5/9(F-32) where F is the Fahrenheit temperature and C is the Celsius temperature. Write a Python function named celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalentsarrow_forwardUsing Python, write an application that will calculate a loan payment. To complete this, you are required to write 2 functions, LoanPayment and InterestOnlyLoanPayment, as well as a test application that calls each of the functions to get the payment amount based on parameters supplied to the functions. The test application should output both the loan payment and the interest-only loan payment based on input values from the user. The LoanPayment function is defined as follows: Payment = Loan amount / Discount factor The discount factor is {[(1 + i)^n] - 1} / [i(1 + i)^n], where you have the following: n = Payments per year × Number of years i = Annual interest rate / Payments per year Take for example the following: D = {[(1 + 0.005)^360] – 1} / [0.005(1 + 0.005)^360] = 166.7916, where n = 12 × 30 and i = 0.06 / 12.

The data should be collected for n employees. The value ofn should also be accepted as input. All amounts should be displayed with three decimal places. The output should be displayed as a table containing the Employee name, Average Sales and Bonus. The program must define and use a function with Total Sales as a parameter and should calculate the Average Sales and Bonus for each employee. Bonus must be calculated based on the following table: Average Sales (AS) ASAS<7500 75002AS<10000 AS210000arrow_forward
- An automated donation machine accepts donations via 10 or 20 bills to a maximum of $990. The machine needs to print a receipt with the donation amount in English, rather than numerically. Complete the following function which converts any number between 10 to 990 dollars to English.NOTE: You may define and use another function if necessary.NOTE: You should use arrays for this task. Use of switch statements or very long if/else if statements for printing is not allowed. However, using if/else if/else statements for the logic of your algorithm is permitted.NOTE: This function returns the result, and does not print it. Make sure the result is not lost when you return. Example function input and output (donation is 110):Input: 110Output: “one hundred ten dollars” string convertToEnglish (int donation); in C++ #include <iostream>#include <string>using namespace std; string convertToEnglish (int donation); int main() {int donation;cin>>donation;…arrow_forwardPython onlyYour task is to write a function called analyse_macronutrients which takes three arguments in the following order: The grams of fat in a serving. The grams of carbohydrates in a serving. The grams of protein in a serving. The approximate number of calories per gram for each of the above macronutrients is found in the below table Macronutrient Calories per gram Fats 9 Carbohydrates 4 Proteins 4 To calculate the number of calories contributed by a particular macronutrient, you have to multiply its weight by its corresponding calories-per-gram value. After performing this calculation for each of the three macronutrients, your function should print the percentage of total calories contributed by each of the three macronutrients. add on to this: # Write your `analyse_macronutrients` function here. print('> Frozen pizza') analyse_macronutrients(18, 39, 8) print('> Big Mac') analyse_macronutrients(30, 45, 25) # Add another examplearrow_forwardYou are tasked with writing a small part of a museum's ticketing system. The museum calculates ticket prices using the following rules: $20.00 per admission. Children under 15 get a 50% discount. Seniors (60 years and older) get a 25% discount. Write a Python function that takes a list of customers' ages and returns the total cost for the group. Your function must match the docstring below. You do not need to include the docstring in your solution. '''Function -- get_ticket_costCalculates the cost of museum admission for a group.Parameter:group_ages -- A list of integers representing customer ages.Returns:The total cost for the group, a float. The return value is not rounded.''' Example get_ticket_cost([10, 39, 40]) returns 50.0arrow_forward
- in Python please. You buy an international calling card to India. The calling card company has some special offers. If you charge your card with $15 or $20, you don't get anything extra. For a $35 charge, you get $6 of extra phone time. For a $60 charge, you get $7 of extra phone time. For a $120 charge, you get $15 of extra phone time. Write a function that asks the user for the amount he/she wants on the card and returns the total charge that the user gets. Note: Values other than those mentioned earlier are not allowed. Include appropriate comments to make your code more readable.arrow_forwardin python Create a single function that will return the area OR the volume of an object. i.e. if you call the function with the values (10,8), it will return 80; if you call the same function using values (10,2,3) it will return 60.arrow_forwardplease code in python A car's fuel consumption may be expressed in many different ways. For example, in Europe, it is shown as the amount of fuel consumed per 100 kilometers. In the USA, it is shown as the number of miles traveled by a car using one gallon of fuel. Your task is to write a pair of functions converting l/100km into mpg, and vice versa. The functions: are named liters_100km_to_miles_gallon and miles_gallon_to_liters_100km respectively; take one argument (the value corresponding to their names) Complete the code in the editor. Run your code and check whether your output is the same as ours. Here is some information to help you: 1 American mile = 1609.344 metres; 1 American gallon = 3.785411784 litres.
