[Tutor] Calling a function by string name

[Smith, Jeff]

Title: Message

I have an object and I want to call a method that I have constructed the name for in a string.

 

For example:

str_method = 'myfun'

obj.str_method

 

Of course, this fails.  I know I could probably do this with exec but is there a better way?

 

For context, the specific application is a wrapper to calling p4python. Note that the second return (under the else under the try) is where I want to call 'method' which is the string name of a method valid for self._client.

 

    def _p4runner(self, method, *args):
        'runs a Perforce command'
        try:
            if callable(method):
                return method(*args)
            else:
                return self._client.method(*args)
        except p4.P4Client.error:
            raise
        except:
            if self._client.errors:
                raise p4.P4Client.error('\n'.join(self._client.errors))
            else:
                raise

 

Clear as mud?

Jeff
