Question

How can I get convert a user input from a string to a symbol such as / * %+- without specifying every symbol

Answer 1

As evil as it is, you have eval()

E.g.

a = "5"
b = "39"
c = input()

print(eval(a+c+b))

Let's say you input "+", the output would be 44.

Answer 2

Based on: https://stackoverflow.com/questions/1740726/turn-string-into-operator

a = 5
b = 39
c = input()

ops = {
"+": (lambda x,y: x+y),
"-": (lambda x,y: x-y),
"/": (lambda x,y: x/y),
"*": (lambda x,y: x*y)
}

print(ops[c](a,b))
