Question

Given two integers a and b, your task is to calculate:

• a+b
• a- b
• a*b
• a//b

Input

User Task: Since this will be a functional problem, you don't have to take input. You just have to complete the function operations() that takes the integer a and b as parameters.

Constraints:

• 1 <= b <= a <= 1000

Note: It is guaranteed that a will be divisible by b.

Output

Print the mentioned operations each in a new line.

This is my code:

def operations(X,Y):
  return X+Y

def minus(X,Y):
  return X-Y

def multi(X,Y):
  return X*Y

def div(X,Y):
  return X/Y

X = 15
Y = 3

print(minus(X,Y))
print(operations(X,Y))
print(multi(X,Y))
print(div(X,Y))

It would be a huge help if someone tells me if the code I am doing has something wrong with it.

Answer 1

if you use (/) 11/3 in division then it will return float value (3.666666...) if you use(//) 11//3 it will give you a rounded int value (3)

Answer 2

I don't think the problem asks you to add the functions minus , multi and div . You only need to implement the function operations and make print the result of the four operation each in one line. Which can be done like this:

def operations(a, b):
  print(a + b)
  print(a - b)
  print(a * b)
  print(a // b)

Notice how I used a double slash ( // ) for division instead of a single slash ( / ). Because a single slash in python will give you a float value even though a and b are integers. ie. 4 / 2 will return 2.0 where the problem is clearly asking for integer values (cf. the note), in this case 2
