python直接调用求解一元二次方程，一元三次方程函数

安装包

pip install zy

安装成功之后引用包

from zy.math import equation as eq
a = eq.f1(1,0,-1) #  a=1 , b=0,c = -1
print(a)

'''
输出结果为
['x1=1.000000', 'x2=-1.000000']
'''

求解一元三次方程

from zy.math import equation as eq
b = eq.f2(1,0,-1,2) 
print(b)

'''
['X1 = -1.521380', 'X2 = 0.760690 + 0.857874i', 'X3 = 0.760690 - 0.857874i']
