Can someone please show me an easy efficient way to handle the exceptions in this code?

Question

I'm trying to make a simple calculator using the new material I've learned.

Answer 1

def add(x,y):
return x+y
def sub(x,y):
return x-y
def mult(x,y):
return x*y
def div(x,y):
return x/y
x = int(input())
op = input()
y = int(input())
ops = {
'+': add, '-': sub, 'x': mult, '/': div
}
try:
func = ops[op]
result = func(x,y)
print('{0} {1} {2} = {3}'.format(x,op,y,result))
except:
print('Invalid')

if you want to be proper do except KeyError

Answer 2

Kamil Hamid thank you. I'm trying to find an efficient way to handle exceptions with x and y as well. I know how to do it with try and except but I'm trying to find a more efficient way to handle them.

Answer 4

1. Which exceptions?
2. Try/except is the way of handling exceptions. What do you want to change?
