Python| sympy.is_nonpositive() 方法

在 simpy 模块中，我们可以使用 sympy.is_nonpositive()函数测试给定数字 n 是否为非正数

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

代码#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)

输出：

True
False

代码#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)

输出：

True
