Python | sympy.is_zero() method

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)

Output: 

True
False
