Solve the following python programming problem given the following code:
@register.tag
def mkrange(parser, token):
assistant
#Here is the Python code you requested.

    """Accepts the same arguments as the \range\ builtin and creates
    a list containing the result of \range\.
    Syntax:
    {% mkrange [start,] stop[, step] as context_name %}
    For example:
    {% mkrange 5 10 2 as some_range %}
    {% for i in some_range %}
    {{ i }}: Something I want to repeat
    {% endfor %}
    Produces:
    5: Something I want to repeat
    7: Something I want to repeat
    9: Something I want to repeat
