is there an equivalent of javascript's this["myMethod"] for the currently running script?

[markturansky]

I'd like to dynamically find and invoke a method in a Python CGI.

In javascript, the running script is 'this' (Python's 'self'), except
that 'self' is not defined.

I want to do this:

var m = this["MethodName"]; //where the method name is passed via an
http variable
m(); //this invokes a method in javascript

How do I do the same in python?

self["MethodName"] fails...

Don't know if this is the best solution... but you need something around
the lines of:
.... print "bar"
....

>>> m = locals()["foo"]
>>>
>>> m() bar
>>>

i.e., you need to play a bit with locals()

Hope that helps

getattr. Read the documentation, it's all in there.

I'd like to dynamically find and invoke a method in a Python CGI.

getattr(self, methodName)()

But make sure to validate user input first, of course.

I'd like to dynamically find and invoke a method in a Python CGI.

boundmeth = obj.meth # nb: no ()

# stuff.....

boundmeth() # call it, with args if needed

Yes, that is exactly what I was looking for. Thank you. I will read
more about 'locals()', but a quick test proved you right.

'self' is not defined in this circumstance. The poster above (using
'locals()') has it right.

getattr does not work on a running script (afaik) because 'self' is
undefined. The poster above got it right using 'locals()'
