If you are interested in manipulating vectors the following package
built using sympy might be of interest -
https://galgebra.readthedocs.io/en/latest/
especially the way that the different products and derivatives are
implemented (the gradient of a scalar function f is simply grad*f and
the divergence of a vector function F is grad|F). It will run in
Juypter notebook. You define the type of coordinate system you want by
inputting a metrics tensor (rectangular, cylindrical, and spherical are
in the examples).

Sorry I couldn't explain. The SymPy(vectors) does work great at me as
well. I meant on mobile phone. on mobile SymPy ver==1.1.1
I can't update latest ver(1.10.1) yet. When I update SymPy 1.1.1 to
1.10.1 I display some '*.rej*' file with errors on my log.

Hey guys, when i add interesting vector import my code, i
display that error : *TypeError: unsupported operand type(s)
for +=: 'NoneType' and 'NoneType'*
