原文:https://www.geesforgeks.org/python-sympy-is_positive-method/
在 simpy 模块中，我们可以使用 sympy.is_positive()函数来测试给定的数字 n 是否为正。
Syntax: sympy.is_positive(n)
Parameter: n; number to be tested
Return: bool value result
代码#1:
蟒蛇 3
# Python program to check positive number
# using sympy.is_positive() method
# importing sympy module
from sympy import *
# calling is_positive function on different numbers
geek1 = simplify(-21).is_positive
geek2 = simplify(0).is_positive
print(geek1)
print(geek2)
输出:
False
True
代码#2:
蟒蛇 3
# Python program to check positive number
# using sympy.is_positive() method
# importing sympy module
from sympy import *
# calling is_positive function on different numbers
geek = simplify(-002).is_positive
print(geek)
输出:
False
