Instructions
The company you work for wants to reduce their carbon footprint, so they want you to write a program to calculate the power usage and cost of running their electronics.
1. Get extra hours
Your employer has a program that calculates the time it takes to run different electronics. Currently, the time is stored in hours. When your employer added the hours, they noticed that the time duration was not correct. They want you to add 3 extra hours to the time data. They would also like to know how many "extra" hours there are after converting the data to "full" days (a day is 24 hours). The time to convert may not be in full days.
Implement a function get_extra_hours() that accepts an integer which holds the number of hours.
The function should make the appropriate "extra hours" adjustment, and then return an integer representing how many hours needs to be removed from the total to get the time in "full" days.
>>> get_extra_hours(25)
42. Get kW value
Your employer wants to know the power usage of the different electronics in kW. kW stands for kilowatt, where watts are a unit of power. Kilo in the unit name is a prefix in the metric system meaning 1000. One kilowatt == 1000 watts.
Implement a function get_kW_value() that accepts an integer which holds the number of watts.
The function should then return the watts as kilowatts rounded to 1 decimal place.
>>> get_kW_value(1150)
1.23. Get kWh value
To be able to calculate the cost of running the electronics, your employer needs to know the power usage in kWh. kWh stands for kilowatt-hour, where hour is a unit of time. One kilowatt-hour == 1000 watts used for 1 hour. An hour is made up of 60 minutes and a minute is made up of 60 seconds. One hour is equal to 3600 seconds. To calculate the kWh value, you must convert watts to kW, and then floor-divide the result by 3600.
Implement a function get_kWh_value() that accepts an integer which holds the number of watts.
The function should then return the kilowatt-hours as an integer.
>>> get_kWh_value(5000000)
14. Get efficiency
Electronics are not 100% efficient. Therefore, your employer wants you to calculate the efficiency of the electronics. To get efficiency, you must divide the power factor (a float between 0 and 100) by 100.
Implement a function get_efficiency() that accepts a float that holds the power factor.
The function should then return the calculated efficiency as a float.
>>> get_efficiency(80)
0.85. Get cost
Your employer wants to know the cost of running the electronics. The cost of running the electronics is the power used multiplied by the cost per kWh. The power used is the power given divided by the calculated efficiency.
Implement a function get_cost(<watts>,<power_factor>,<price>) that accepts an integer that holds the number of watts, a float that has the power factor, and a float that holds the cost per kWh.
The function should then return the cost of running the electronics as a float.
>>> get_cost(5000000, 80, 0.25)
