Python | sympy.is_zero() method

20 June 2025

In the sympy module, we can test whether a given number n is zero or not using sympy.is_zero() function.

Syntax:  sympy.is_zero(n)
Parameter:  n; number to be tested
Return:  bool value result

Code #1:

Python3

# Python program to check zero 
# using sympy.is_zero() method
 
# importing sympy module
from sympy import *
 
# calling is_zero function on different numbers
geek1 = simplify(1).is_zero
geek2 = simplify(0).is_zero
 
print(geek1)
print(geek2)

Output:

False
True

Code #2:

Python3

# Python program to check negative number 
# using sympy.is_negative() method
 
# importing sympy module
from sympy import *
 
# calling is_negative function on different numbers
geek1 = simplify(0.0).is_zero
geek2 = simplify(2).is_zero
 
 
print(geek1)
print(geek2)
