Python| sympy.is_negative() 方法

在 simpy 模块中,我们可以使用 sympy.is_negative()函数测试给定数字 n 是否为负数。

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

代码#1:

Python3
# 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)


Python3
# 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
False

代码#2:

Python3

# 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
