Question

. A manufacturing company measured the productivity of its workers and found that:

• between the hours of 6am and 10am they could produce 30 pieces/hour/worker

• between 10am and 2pm they could produce 40 pieces/hour/worker

• between 2pm and 6pm they could produce 35 pieces/hour/worker.

Write a function pieces_produced takes a number that represents a starting hour between 6am

and 6pm, in twenty-four hour format (between 0 and 23), along with the number of workers and

returns a number that represents the total number of pieces produced during that hour. If the

user enters an invalid hour or number of workers, the function should return -1. Save the function

in a PyDev library module named functions.py

Write a testing program named t01.py that teststhe function by asking the user to enter hours and

number of workers and prints the total number of pieces produced.

A sample run:

Time of the day: 6

Number of workers: 10

The total number of pieces produced:300

Or

Time of the day: 35

Number of workers: 10

Can not perform the calculation

• test your program with 3 different data than the examples, you may assume that the user will

only enter numbers.

• Copy the results to testing.txt.

Answer 1

Program code in to1.py:

def pieces_produced():
    time=int(input("\nTime of the day:"))
    workers=int(input("Number of workers:"))
    if(workers<0):
        print("Number of workers should be non-negative value....")
        pieces=-1
    else:
        if(time>=6 and time<10):
            pieces=30*workers
        elif(time>=10 and time<14):
            pieces=40*workers
        elif(time>=14 and time<=18):
            pieces=35*workers
        else:
            pieces=-1
            print("Time is not valid...It should be between(6-18)")
    return pieces
for i in range(3):
        value=pieces_produced();
        if(value==-1):
            print("Can not perform calculation.")
        else:
            print("The total number of pieces produced:",value)

Data in testing.txt:

>>>
= RESTART: C:/Users/Sappati Praveena/AppData/Local/Programs/Python/Python38-32/to1.py

Time of the day:18
Number of workers:23
The total number of pieces produced: 805

Time of the day:5
Number of workers:-3
Number of workers should be non-negative value....
Can not perform calculation.

Time of the day:20
Number of workers:5
Time is not valid...It should be between(6-18)
Can not perform calculation.
