Question

Enter two integers and operators from the user and create a program that corresponds to the operator you entered.

(You create a program to calculate any of the operators (+,-,*) that are entered.)

integer input:5

operator input:+

integer input:3

5+3=8

Answer 1

Is easy:

# method 1: using `unsecured` eval()
printk(eval(input('Enter: ')))

# method 2: without using eval()
e = input('Enter two numbers separated with a space: ').split()+list(input('Enter the operator: '))
k = lambda a='0',b='0',o='+':(a:=int(a),b:=int(b),o:=o if o in'+-/*'else'Operator is not set')and(a+b if o=='+'else a-b if o=='-'else (a/b if a!=0 and b!=0 else 0) if o=='/'else a*b if o=='*'else o)
print(k(*e))

#method 3: your own method!

Answer 2

Could you tell me more about method 1?

Answer 3

eval() is a function that can interpret a pythonic syntax piece of code but as so it carries some dangerous issues with it.
