Question
PYTHON
Write a python function called calc_toll() that has three different parameters such as: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The function also should returns the correct toll fee (float), based on the information in the picture.

Transcribed Image Text:**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)
**Example:**
The function calls below, with the given arguments, will return the following toll fees:
- `calc_toll(8, True, False)` returns 2.95
- `calc_toll(1, False, False)` returns 1.90
- `calc_toll(3, False, True)` returns 2.15
- `calc_toll(5, True, True)` returns 1.05

Transcribed Image Text:```python
def calc_toll(hour, is_morning, is_weekend):
# Type your code here.
if __name__ == '__main__':
print(calc_toll(8, True, False))
print(calc_toll(1, False, False))
print(calc_toll(3, False, True))
print(calc_toll(5, True, True))
```
This snippet appears to be a Python program that defines a function `calc_toll` intended to calculate a toll based on the hour, whether it is morning, and if it is a weekend. The function body is currently not implemented, indicated by the comment `# Type your code here.`
In the main block of the program, the `calc_toll` function is called four times with different arguments:
1. `calc_toll(8, True, False)`: This checks the toll for 8 AM on a weekday.
2. `calc_toll(1, False, False)`: This checks the toll for 1 PM on a weekday.
3. `calc_toll(3, False, True)`: This checks the toll for 3 PM on a weekend.
4. `calc_toll(5, True, True)`: This checks the toll for 5 AM on a weekend.
Each result is printed to the console. The function and its logic need to be implemented to actually calculate and return toll values based on the provided parameters.

Write a function that takes in the current temperature and a boolean value telling if it is raining and it should return True if Alfonso will wear a jacket and False otherwise. Try solving this problem with a single line of code. def wears_jacket(temp, raining): """ >>> wears_jacket(90, False) False >>> wears_jacket(40, False) True >>> wears_jacket(100, True) True """ *** YOUR CODE HERE *** Note that it should either return True or False based on a single condition, whose truthiness value will also be either True or False. Part 2: Rewrite the above function with a lambda expression.arrow_forwardCreate a function named fnTuition that calculates the tuition for a student. 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
- In computer animation, a "jiffy" is commonly defined as 1/100th of a second. Define a function named jiffies_to_seconds that takes the number of "jiffies" as a parameter, and returns the number of seconds. Then, write a main program that reads the number of jiffies (float) as an input, calls function jiffies_to_seconds() with the input as argument, and outputs the number of seconds. Output each floating-point value with three digits after the decimal point, which can be achieved as follows: print (f'{your_value:.3f}') Ex: If the input is: 15.25 the output is: 0.152 The program must define and call the following function: def jiffies_to_seconds (user_jiffies) 461710.3116374.qx3zqy7 LAB ACTIVITY 7.11.1: LAB: A jiffy 1 # Define your function here 12345 3 if __name__ main.py == '__main__': # Type your code here.
