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