Question
1. Please write a python 3 program and show all outputs.
PLEASE SEPARATE FILES ALSO SEE EXAMPLE OF PART ONE BELOW.
Complete the TODOs in waterregulation/controller.py and waterregulation/decider.py.
Complete the TODOs in waterregulation/test.py and waterregulation/integrationtest.py. A single integration test may be sufficient. However, your unit tests in test.py should include at least one test for each specified behavior.
python -m unittest waterregulation/test.py and python -m unittest waterregulation/integrationtest.py should have no failures.
Running coverage run --source=waterregulation/controller.py,waterregulation/decider.py -m unittest waterregulation/test.py; coverage report shows 90%+ coverage..
Satisfy the linter such that pylint waterregulation gives no errors and and flake8 waterregulation gives no errors. You may have to add docstrings to your test files.
______________________________________________________________________________________________________________________
Example Test for this program from part one. This is only an example of orginal instructions and output code.
Original Instructions
python -m unittest integration-test should have no failures. Don't edit integration-test.py, edit your code to make it pass.
Add unit tests to unit-test.py such that coverage run --source=calculator -m unittest unit-test; coverage report shows 100% coverage.
All of the tests in unit-test.py should pass.
Satisfy the linter such that pylint calculator gives no errors and flake8 calculator gives no errors. See (PEP257)[https://www.python.org/dev/peps/pep-0257/] if you'd like more information about docstrings. There are quite a few docstrings to add, but for this exercise you don't need to get too creative: """ this method adds two numbers """ is sufficient.
Bonus goal
One of our specs for calculator says the following:
The add, subtract, multiply, and divide methods shall both:
Return the result of the operation
Enter the result of the operation back into the calculator
This makes it possible to perform the following sequences of operations:
calculator.enter_number(2)
calculator.enter_number(3)
calculator.add() # Returns 5, and now 5 is now 'in the calculator'
calculator.enter_number(1)
calculator.subtract() # Returns 4 because 5 - 1 = 4

Explanation / Answer
HI ,, See below simple one for area of triangle
# Python Program to find the area of triangle
a = 5
b = 6
c = 7
# Uncomment below to take inputs from the user
# a = float(input('Enter first side: '))
# b = float(input('Enter second side: '))
# c = float(input('Enter third side: '))
# calculate the semi-perimeter
s = (a + b + c) / 2
# calculate the area
area = (s*(s-a)*(s-b)*(s-c)) ** 0.5
print('The area of the triangle is %0.2f' %area)
output
The area of the triangle is 14.70
---------------------------------------
# Python Program to find the L.C.M. of two input number
# define a function
def lcm(x, y):
"""This function takes two
integers and returns the L.C.M."""
# choose the greater number
if x > y:
greater = x
else:
greater = y
while(True):
if((greater % x == 0) and (greater % y == 0)):
lcm = greater
break
greater += 1
return lcm
# change the values of num1 and num2 for a different result
num1 = 54
num2 = 24
# uncomment the following lines to take input from the user
#num1 = int(input("Enter first number: "))
#num2 = int(input("Enter second number: "))
print("The L.C.M. of", num1,"and", num2,"is", lcm(num1, num2))
output
The L.C.M. of 54 and 24 is 216
