Question

Module and Import

For these 3 problems,

-You are writing a function to calculate a formula in the module.

-You are going to import the modules to the main.

-Write 3 more functions in the main

-Don't do any formula calculation in the main just use module functions and return your result.

-Call each main function twice to test the provided values.

1. Meter to Feet and Inches

One meter equals 39.37 inches and 1 foot equals 12 inches.

Write a function m_2_ft_inch (m) under the module meter_feet.py.

Import it to the main and another function named meter_to_feet_n_inch (meter) in the main. Call your function twice to test these 2 values.

i) 78 meter

ii) 245 meter

Hint: Use the remainder to solve this problem

Note: The result must be in feet and inches, suppose if it is 1.73 meters, your program should be able to print, 5 feet 8 inches

2. Kinetic Energy

Kinetic Energy equals 0.5 times mass (m) times square of velocity (v)

Write a function k_energy(m, v) under module KE.py. Import it to the main then write a function named kine_energy that accepts two arguments of mass and velocity.

Call your function twice to test the following parameters.

i) Object_A: mass = 230 kg, velocity = 12 m/sec

ii) Object_B: mass = 330 Kg, velocity = 11 m/sec

3. Future Value Calculation

Suppose you have a certain type of saving account that earns compound interest in your deposit. You can calculate your amount with formula,

F = P . (1 + i) ^ t

where,

F = Future value of the account after a certain time period

P = current balance of your account

i = annual interest rate, percent must be divided by 100 in calculations

t = number of years

Write a function my_future_value (p, i, t) under module future_value.py. Import the module to the main. In main write a function calculate_future_value (PV, interest, time). Call this function twice to calculate the future value with arguments for present value, interest rate, and the number of months as below.

a) P = $25000, i = 14.37% and t = 10 years

b) P = $133000, i = 16.70% and t = 13 years

Answer 1

I have given you the codes for main function and other three functions with comments and I have given you the output screens with above testcases

Hope this helps

Meters to feet and inches function code-

import math

#function for convertion of meters to feet and inches 
def m_2_ft_inch(m):
    mynewlength = 100*m/2.54 + 0/2.54 
    mynewfeet = math.floor(mynewlength/12)
    mynewinch =mynewlength-12*mynewfeet
    z=str(mynewfeet)+"feet "+str(math.floor(mynewinch))+"inches "
    return z

Kinetic energy conversion function code-

#function to caluate kinetic energy 
def k_energy(m,v):
    kineticenergy=0.5*m*(v)**2
    return kineticenergy

Future value calculation function code-

#function to calculate future value 
def my_future_value(p,i,t):
    futurevalue=p*(1+i/100)**t
    return futurevalue
