In sympy module, we can test whether a given number n is positive or not using sympy.is_positive() function.
Syntax: sympy.is_positive(n) Parameter: n; number to be tested Return: bool value result
Code #1:
Python3
# Python program to check positive number # using sympy.is_positive() method# importing sympy modulefrom sympy import *# calling is_positive function on different numbersgeek1 = simplify(-21).is_positivegeek2 = simplify(0).is_positiveprint(geek1)print(geek2) |
Output:
False True
Code #2:
Python3
# Python program to check positive number # using sympy.is_positive() method# importing sympy modulefrom sympy import *# calling is_positive function on different numbersgeek = simplify(-0o2).is_positiveprint(geek) |
Output:
False
Code #3:
The sum of two positive terms is positive
Python3
# importing sympy libraryfrom sympy import *from sympy import symbolsa, b = symbols('a, b', positive=True)geek = a + bprint(geek.is_positive) |
Output:
True
