在 simpy 模块中,我们可以使用 sympy.is_nonpositive()函数

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

来测试给定的数字 n 是否为非正

代码#1:

Python 3

# 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:

Python 3

# 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
