Answer 1

in c = ...

It needs a closing ")" bracket

Answer 2

Check this code out. It seems like you use regular math expressions in script.

ex. "c4" you can not do this because python doesn't know what operation you want.

"c*4" is the way to write that. Check out the this updated code of yours and look at the small changes in operations I made. Also look at barackets
