numeric type conversion

Question

I find that Int(x) can't really change the type of x, I need to create a new variable to save it .It same as before when I print it again

Answer 1

x = str(input( ))
#storing input as string
y = int(x) + 2
print(y)

The need of creating a new variable is imminent.
But it still works

Or

you can simply print what you want

print(int(x) + 2)

This way, you don't need to create anything new
