You can use conditional statements {if-else} for it.

Use Let num = str.split('+'); # return an array Then add the num by a loop

eval('2+3') Gives the output 5 where 2+3 is a string and is "evaluated" hence the method name eval()

Use python built in operator module and a dict to get corresponding operand
