Mine Minecrafft, if you are using:
inp = int(input('Enter a number'))
and user does input 4 5, int conversion will fail and you will get a ValueError. To avoid this, you should put your relevant code in a try ... except ... block.

An input is *always* string.
But you can check if it's convertible to int or not.
inp=input()
try:
int(input)
except:
... # If we get here
# it was not an int

The point is, as I have written:
The type of input is automatically ALWAYS string.

Python input function always gives back a string, no matter what characters are entered. But the content of this string can be meant as text or number. This can be checked by using the several string methods.
inp = input('Your name please:') # <- user enters 'John'
if inp.isalpha(): # <- checks for alphabetical characters
...
num = input('Enter number:') # < user enters 16
If num.isdigit(): # <- checks for digits
...
There are also some other methods for checking:
isalnum(), isspace(),...
Keep in mind, that input can be a mix of the mentioned characters.

Thanks for giving me the code I looked for but If i put an int(input()) or a float(input()) it becomes an int or float in an input() yes that is string but it can't be an int

Int are numbers string are text surely you can write numbers in a text module but it won't be seen as an int and you cant write text in int either

I remember that on Idle and on reple.it you culd use a float(input()) to input both string and int but it does not work here so that is also a problem but the main question is still how do I define a string
Do I write
If inp= str:
