Why does the input function always return a string?

If I have such a simple code

varry = 1
print(type(varry))

it gives me - class 'int'

But if I have this:

varry = input()
print(type(varry))

And I type 1, it gives me class 'str'

Tell me please - why is it so and how should I write a program so that it defines a variable I enter correctly as int, str or float?

The built-in function input always returns a string, regardless of whether that string might be comprised of solely numerical characters. If you are sure the result can represent a number, then convert it:

varry = int(input())

Now the type of varry will be int, assuming this conversion doesn't raise a ValueError

What you input to your program is always of type str. if you want Python to deduce the type of the input itself, use data = eval(input()) or, for more safety:

import ast 
data = ast.literal_eval(input())

varry = int(input())

print(type(varry))

You have to convert it to int using int() method
