I imagine that you are reading these columns into Python as a string. A way you could easily split this string into the list you desire is to use the string method split(). Here is some example code.

def get_genres(row):
    """
    :param row: a string containing a set of genres seperated by '|'
    :return: a list of strings containing the genres of the row
    """
    return row.split('|')
