Calculator in python

Question

I am trying to make calculator that can solve expressions with basic 4 operators, like 1+2*3-4/5, however it does not work and I do not know what is wrong. Please check my code.

Answer 1

Your dispatching is incorrect. The way you defined your function it will always try to split by '*', which basically calls the ret function recursively with the same arguments...

You'll have to check first whether an "operator" is present in your argument string at all.

Think again!
