Use if with and function?

[ibutun]

Hi members, i am new here and I have so many requests in phyton to learn... Please help me... i write a code like this but not working

num = input("Please enter a number: ")

if num.isalpha():
    print(f"{num} is not a number.")

elif type(num) == int and (num %2) == 0:    #If the value entered is a number and divided by two,
    print(f"{num} çift sayıdır")            #say it as an even number

else:
    print(f"{num} is an odd number")

why this code not working...
if i enter 4 , it says is an odd number... (this is false)
if i enter 5, it says is an odd number...
if i enter a, it says is not a number...

how do i fix it?
