Python Day 9

Today we will try the basic Arithmetic Operators including , + , - ,* ,/ and squares in Python.

Arithmetic Operators:

1. The first line contains the sum of the two numbers.
2. The second line contains the difference of the two numbers (first - second).
3. The third line contains the product of the two numbers.
4. The fourth line contains the division of the two numbers.

Solution:

def arith_op(a,b):
    n1=a+b
    n2=a-b
    n3=a*b
    n4=a/b
    print (n1,n2,n3,n4, sep="\n")

arith_op(2,3)

#Alternative Solution
print("%d\n%d\n%d"%(a+b,a-b,a*b))

Output

arith_op(2,3)

Division:

Read two integers and print two lines. The first line should contain integer division,  a//b. The second line should contain float division, a /b.

a = int(input())
b = int(input())
print(a//b, a/b,  sep="\n")

Output:

1
1.33333333333

Square List:

Read an integer N. For all non-negative integers i< N , print i^2.

Solution:

[print(i*i) for i in range(n)]

Output:

0
1
