Why I get 2+3 output as 23 in python?

Answer 1

if you use an input to get the two numbers from the keyboard, like this:

a = input() -> you type 2
b = input() -> you type 3

print(a+b) -> you will get concatenation because the inputs default to strings:
'2' + '3' = '23'

instead you can do this:

a = int(input()) -> you type 2
b = int(input()) -> you type 3

print (a+b) -> since a and b are now int, they will be evaluated as math addition meaning:
2 + 3 = 5 (notice no more quotes, because they are no longer strings)

Answer 2

2 and 3 must be string
Use type(2) or type(3) to check whether they are string or not

Answer 3

Ok

Answer 4

My question is that when i add 2+3 i didn't get output as 5
Instead i get 23
