Remote feature branches for add, sub, mul, and div respectively.
Two people will work together on a single feature branch; one implements and another makes test cases.

1. implement an sub method
   the method receives two float inputs and output is subtraction result of first input to second input as float

2. implement a test for sub method
   test will be done on the implemented script

Example)

calc=Calculator()
#two float inputs
a=2.0
b=2.0

assert calc.sub(a,b) == 0.0

>>> Passed

We will make a mul function

#input can be any real number
x = 2.0 # real number
y = 1.1 # real number

#body will multiply this two of values.
x * y = 2.2 # output : real number

test code

assert calc.mul(x, y) == 2.2

we will test ten of gugudan examples

Make subtract function for calculator.
Takes two float input and returns float output result of subtraction of first input to second input.
Implement 'sub()' in class Calculator, 'calculator.py'.
Test will be in 'test_calculator.py'

like

cal=Calculator()
float result = cal.sub(float a, float b)  

example:

cal = Calculator()
result =cal.sub(2,2)
assert result ==0 

it will pass the test

In calculator.py, implement 'div()', a divide function. This function is given two numbers float type a, b and returns float type a/b. Test will be in 'test_calculator.py'

example

cal = Calculator()
result = cal.div(4.2, 2.1)
assert result == 2.

This test will pass.

cal = Calculator()
result = cal.div(4.2, 2.1)
assert result == 3.

This test will fail.

The base files will be working as simple guidance for future collaboration.

1. calculator.py

• includes Calculator abstract class (without any implementation).

2. test_calculator.py

• includes TestCalculator abstract class (with the only declaration of test cases).

1. implement an add method
   the method receives two real-valued inputs and outputs a sum of the two

2. implement a test for add method
   test will be done on the implemented script

Example)

calc = Calculator()
# input can be any real number
x = 1.0
y = 1.0

assert calc.add(x, y) == 2.0
print ("Passed")

>>> Passed
