Transform string "+" or "*" into arithmetic operators

We can convert a string to a number: int("5") => 5 Can we transform string "+" or "*" into arithmetic operators?(without eval())

You can do something like this: from operator import add, mul op = {'+': add, '*': mul} print(op['+'](2, 3)) # 2+3=5 print(op['*'](2, 3)) # 2*3=6 https://code.sololearn.com/cBp52U0M2ysS/?ref=app

Yes we can try this: x=chr(ord("+")) print(x) >>> + And, x=chr(ord("*")) print(x) >>> *

Not directly I don't think. You can use if if symbol == "+": print(a+b) Or exec exec("print(a" + symbol + "b)")
