Python program for addition and subtraction of complex numbers

  • Last Updated : 30 Jan, 2020

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)
