How do you convert variable types?

Question

In the following code the console on this app tells me I'm comparing a string to a int and thus it doesn't work. Is there a mistake in my code, or is it a problem with the app?

x = input("enter a number")

int(x)

if x > 0:
print("True ")

Answer 1

Or you can write it as
X=int(input("enter a num"))

Answer 2

if your input is numuerical string as "1"
you can use print(int("1"))
if your input is numuerical string as "a"
you can use print(ord("a"))

Answer 3

I set up new variable y. y becomes the x in integer format. see below

x = input("Enter a number: ")

y = int(x)

if y > 3:
print("True")
