Code runs as pure python but not jupyter notebook

[miner_tom]

Hello to the forum. As you can tell from the title, I am just learning python, and its use as a jupyter notbook.

I have this cell with a few lines of code that seems to run fine, under pycharm, when I use it in a file type of pure python. But when I use that same code in a file type ipynb, I get an "invalid syntax" error.

def quicksort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x < pivot]
    middle = [x for x in arr if x == pivot]
    right = [x for x in arr if x > pivot]
    return quicksort(left) + middle + quicksort(right)

print quicksort([3, 6, 8, 10, 1, 2, 1])

Here is the error:

print quicksort([3, 6, 8, 10, 1, 2, 1])
syntax error



Thank You
