Number List Value Recognition in Python

Question

I am a new programmer learning python, but I am having trouble with a challenge I came up with recently. The challenge is to have the console recognize odd and even numbers through numeric variables (24-32 in this case). It all seems to be functioning but when I run it it immediately skips to the else statement. I am writing in 3.8.2. Thanks for your help!

x = int(input("Enter a number between 24-32: "))
even = (24, 26, 28, 30, 32)
odd = (25, 27, 29, 31)

if x is (even):
  print("true")
  pass
elif x is (odd):
  print("false")
  pass
else:
  print("Please try again with a number between 24-32")
  pass

@andondraif is right. `is` is for object identity and `x` and `(even)` are *not* the same object. If you want membership checks, you should use `in`. — paxdiablo, Oct 14 '20 at 01:35

Wrong syntax. To check if variable is in a tuple or a list, it should be:

if var in tuple:

or

if var in list:

Your code should be like this:

x = int(input("Enter a number between 24-32: "))
even = (24, 26, 28, 30, 32)
odd = (25, 27, 29, 31)

if x in even:
  print("true")
  pass
elif x in odd:
  print("false")
  pass
else:
  print("Please try again with a number between 24-32")
  pass

How about you try this instead:

x = int(input("Enter a number between 24-32: "))
if x not in range(24, 33):
    print("Please try again with a number between 24-32")
else:
    if x % 2 == 0:
      print("true -> x is even")
    else:
      print("false -> x is odd")
