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 modulefrom sympy import *# calling is_zero function on different numbersgeek1 = simplify(1).is_zerogeek2 = simplify(0).is_zeroprint(geek1)print(geek2) |
Output:
False True
Code #2:
Python3
# Python program to check negative number # using sympy.is_negative() method# importing sympy modulefrom sympy import *# calling is_negative function on different numbersgeek1 = simplify(0.0).is_zerogeek2 = simplify(2).is_zeroprint(geek1)print(geek2) |
Output:
True False
