Python | sympy.is_nonpositive() method

19 June 2025

In simpy module, we can test whether a given number n is non-positive or not using sympy.is_nonpositive() function

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

Code #1:

Python3

# Python program to check non-positive number 
# using sympy.is_nonpositive() method
 
# importing sympy module
from sympy import *
 
# calling is_nonpositive function on different numbers
geek1 = simplify(-21).is_nonpositive
geek2 = simplify(0).is_nonpositive
 
print(geek1)
print(geek2)

Output:

True
False

Code #2:

Python3

# Python program to check non-positive number 
# using sympy.is_nonpositive() method
 
# importing sympy module
from sympy import *
 
# calling is_nonpositive function on different numbers
geek = simplify(-002).is_nonpositive
 
print(geek)
