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:
Python 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:
Python 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
