Python program for addition and subtraction of complex numbers

Given two complex numbers z1 and z2. The task is to add and subtract the given complex numbers.

Addition of complex number: In Python, complex numbers can be added using + operator.

Examples:

Input:  2+3i, 4+5i
Output: Addition is : 6+8i

Input: 2+3i, 1+2i
Output: Addition is : 3+5i

# Python program to add 
# two complex numbers 
  
  
# function that returns 
# a complex number after 
# adding 
def addComplex( z1, z2): 
    return z1 + z2 
  
# Driver's code 
z1 = complex(2, 3) 
z2 = complex(1, 2) 
print( "Addtion is : ", addComplex(z1, z2)) 

Output:

Addtion is :  (3+5j)

Subtraction of complex numbers: Complex numbers in Python can be subtracted using - operator.

Examples:

Input: 2+3i, 4+5i
Output: Subtraction is : -2-2i

Input: 2+3i, 1+2i
Output: Subtraction is : 1+1i

# Python program to subtract 
# two complex numbers 
  
  
# function that returns 
# a complex number after 
# subracting 
def subComplex( z1, z2): 
    return z1-z2 
  
# driver program 
z1 = complex(2, 3) 
z2 = complex(1, 2) 
print( "Subtraction is : ", subComplex(z1, z2)) 

Output:

Subtraction is :  (1+1j)
