I made an expression creator. I only need one more line to fill in which is line 48. I would appreciate it if someone could give me code for line 48 and if any other code is needed just tell me and I can figure out where to put it. Also for lines 49, 51, and 52 I had it return what the variables were equivalent to. In the input it shows that both are equivalent to 0 but the coding on lines 53-58 return it as "answer" and "answer_input" to not be equivilent. Can someone tell me why that is. BTW the output is without line 48.

What have you tried?

You could modify the power symbols and use eval, though I bet you are expected to solve it some other way. I would go for a stack that could work through the symbols, applying powers, holding operators til they are needed, handling parentheses. The operator module would be handy for that, but if you are not allowed to use that you could do it with an if/elif structure for the different operators.
