Python sympy.is_positive()方法
在simpy模块中,我们可以使用sympy.is_positive()函数测试给定的数字n是否为正数。
语法: sympy.is_positive(n)
参数 : n; 待测数
返回: bool value result
代码 #1:
# 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:
# 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
