Python| sympy.is_positive() 方法

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

Syntax:  sympy.is_positive(n)
Parameter:  n; number to be tested
Return:  bool value result 
代码#1:
Python3
# 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)


Python3
# 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
True

代码#2:

Python3

# 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
