remainder operator %

[noweare]

Hello, just joined the forum
I am going through the pdf Automating the boring stuff with Python and I am stuck on this little program.
I don't what I am doing wrong. I did whittle the code down to show the error.
Any help is appreciated.

Oops, found my error I forgot the colon after the if statement. You don't need colons at the end of if statement in C : )

I get the error :

Traceback (most recent call last):
File "C:\Users\Joe\Documents\Python\PcOfPy.py", line 2
if number % 2 == 0
^
SyntaxError: invalid syntax

def collatz(number):
    if number % 2 == 0
        number = number //2
        print(number)
        return number
  
x= 10
collatz(x)

"if number % 2 == 0" should be "if number % 2 == 0:"

hi,
you forgot the ":" at the end of the line two.
if it s not correct after, check your indentation.

hope that will be useful

Yes that was it. Thank you

I am getting started with python but come from a C background.

Another thing that did not work was this.

while (collatz(x) != 1):

I had to do this to make it work

while (x != 1):
    x = collatz(x)
