Python sympy.is_even()方法

在simpy模块中，我们可以用sympy.is_even()函数测试给定的数字n是否为偶数。

语法: sympy.is_even(n)
参数 : n; 待测数
返回： bool value result

代码 #1:

# Python program to check even number
# using sympy.is_even() method
 
# importing sympy module
from sympy import *
 
# calling is_evenfunction on different numbers
geek1 = simplify(30).is_even
geek2 = simplify(13).is_even
 
print(geek1)
print(geek2)

输出:

True
False

代码 #2:

# Python program to check even number
# using sympy.is_even() method
 
# importing sympy module
from sympy import *
 
# calling is_even function on different numbers
geek = simplify(2).is_even
 
print(geek)

输出:

True
