原文:https://www.geeksforgeeks.org/python-sympy-is_zero-method/

在 simpy 模块中,我们可以使用 sympy.is_zero()函数来测试给定的数字 n 是否为零。

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

代码#1:

蟒蛇 3

# Python program to check zero
# using sympy.is_zero() method

# importing sympy module
from sympy import *

# calling is_zero function on different numbers
geek1 = simplify(1).is_zero
geek2 = simplify(0).is_zero

print(geek1)
print(geek2)

输出:

False
True

代码#2:

蟒蛇 3

# Python program to check zero number
# using sympy.is_zero() method

# importing sympy module
from sympy import *

# calling is_zero function on different numbers
geek = simplify(002).is_zero

print(geek)

输出:

False
