Solution 1

Try adding the ~~double dots~~ colon, like

Python

...
if num == 0:
...

Also you need to check the indentations and use parenthesis for the print statements, something like

num = int(input("enter number: "))

if num == 0:
    print ("number is 0")
else:
    mod = num % 2
    if mod > 0:
        print("it is even number")
    else:
        print("it is odd number")

Mika, why?

Wendelius 24-Dec-19 3:31am

You're right, using semicolons is not mandatory. It's just an old, persistent habit :)

Maciej Los 24-Dec-19 4:01am

I thought that using double dots changes something... I can't see the documentation for using double dots in python.
I'm afraid, your answer won't help OP.

Maciej Los 24-Dec-19 4:10am

Ohh....
If you wanted to say that double dots means a colon (which i missed in your answer), you're right, Mika.

Wendelius 24-Dec-19 4:19am

Yep, that would be a colon

Ok.
Happy Christmas to you, Mika.

Happy Christmas to you too Maciej!

Solution 2

Python

if num == 0                     #(error at this line "invalid syntex")

You are missing the colon (:) from the end of the statement. It should be:

Python

if num == 0:

Hawk eye!

It's one of those mistakes that is so easy in Python. And having done it myself so many times, I trend to look more carefully these days.

Happy Christmas to you by the way.

Maciej Los 24-Dec-19 8:52am

Thank you very much, Richard.
Happy Christmas to you too.

Solution 3

~~As i mentioned in the comment to the question, your code looks good to me...~~ I was wrog! A colon is missed. See soultion #2.

I'd suggest to debug your program. See: Intro Python Debugging[^]
This article Invalid Syntax in Python: Common Reasons for SyntaxError – Real Python[^] might be helpful also.
