dynamically adding functions to a Python module
Question: Our framework requires wrapping certain functions in some ugly boilerplate
code:

    
    
    def prefix_myname_suffix(obj):
        def actual():
            print 'hello world'
        obj.register(actual)
        return obj
    

I figured this might be simplified with a decorator:

    
    
    @register
    def myname():
        print 'hello world'
    

However, that turned out to be rather tricky, mainly because the framework
looks for a certain pattern of function names at module level.

I've tried the following within the decorator, to no avail:

    
    
    current_module = __import__(__name__)
    new_name = prefix + func.__name__ + suffix
    # method A
    current_module[new_name] = func
    # method B
    func.__name__ = new_name
    current_module += func
    

Any help would be appreciated!


Answer: use either

    
    
    current_module.new_name = func
    

or

    
    
    setattr(current_module, new_name, func)
