How do you dynamically import a method from a module in the syspath, which you have as a string.

pyimport.py

def get_method_from_file(full_path=['credit', 'syndloan', 'importer', 'sql', 'sql', 'loanDealSql']):
    if len(full_path) == 1:
        return map(__import__,[full_path[0]])[0]
    return getattr(get_method_from_file(full_path[:-1]),full_path[-1])
