loading external paths and modules

[typemytype]

less exec :)
and guessing with formatting an import str

import imp

def loadFilterFromPath(path, functionName):
    """
    loadFilterFromPath("path/to/a/python/file/withAPen.py", "myFilterPen")
    """
    f = open(path, "r")
    try:
        module = imp.load_source("ExternalPenBallWizard", path, f)
        result = getattr(module, functionName)
    except:
        result = None
    f.close()
    return result

def loadFilterFromModule(module, functionName):
    """
    loadFilterFromModule("robofab.pens.filterPen", "FlattenPen")
    """
    try:
        return __import__(module, fromlist=[functionName])
    except:
        return None
