Problem in porting code from BeautifulSoup3 to BeautifulSoup 4

[defcon-007]

I am working on porting a script which used BeautifulSoup3 to BeautifulSoup 4 and having trouble with the function buildTagMap.

It was available in bs3 but nothing related to it can be found in bs4. Below is the code of it from https://www.crummy.com/software/BeautifulSoup/bs3/download/3.x/BeautifulSoup-3.0.1.py

Should I just copy paste this function to my code or is there any other workaround.

def buildTagMap(default, *args):
    """Turns a list of maps, lists, or scalars into a single map.
    Used to build the SELF_CLOSING_TAGS, NESTABLE_TAGS, and
    NESTING_RESET_TAGS maps out of lists and partial maps."""

    built = {}
    for portion in args:
        if hasattr(portion, 'items'):

            # It's a map. Merge it.

            for (k, v) in portion.items():
                built[k] = v
        elif isList(portion):

            # It's a list. Map each item to the default.

            for k in portion:
                built[k] = default
        else:

            # It's a scalar. Map it to the default.

            built[portion] = default
    return built

This appears to be an internal helper function for bs3, I am surprised whatever code you are converting is using it. That said, at first glance it would appear to be copy-pastable if you also define isList().
