Hi everybody,
I ran the following code with sympy:
x = Symbol('x')
y = Symbol('y')
z = Symbol('z')
z = x = I*y
The problem is with this line. You're setting z and x equal to I*y.
Remember that = is assignment in Python. See
http://docs.sympy.org/dev/gotchas.html#variables-assignment-does-not-create-a-relation-between-expressions
for
more information.
What were you trying to do here?
Aaron Meurer
solve (z**3 - z**2 - z - 1, z)
But I got the TypeError: "expected Symbol, Function, Power or Derivative
but got <class 'sympy.core.add.Add'>."
What is the problem?
Thank you all!
