我怎样才能得到这个给我 x = z*y/a ？
from sympy import *
x,y,a,z = symbols('x y a z')
z = a*x/y
solve(z,x) # returns 0!
# would like to get z*y/a
最佳答案
solve(z,x) 正确返回 0，因为您的代码实际上是在询问:
What's the value of x that would cause z to become 0?
您真正想做的(如 here 所述)是解决 a*x/y==z 可以按如下方式完成:
from sympy import *
x,y,a,z = symbols('x y a z')
equation = a*x/y
new_eq = solve(equation - z, x) # its value is [y*z/a]
