Dynamically call methods where method is known by address vs name

[Malcolm Greene]

I know I can do the following:

>>> s = 'lower'
>>> getattr(s, 'upper')()
'LOWER'

But how could I do the same if I had the method 'address' (better
name???) vs. method name?

>>> upper_method = s.upper

How do I combine this upper_method with string s to execute the method
and return 'LOWER'?

Thank you,
Malcolm

In [1]: s = 'hello'
In [2]: f = s.upper
In [3]: f()
Out[3]: 'HELLO'
In [4]: g = str.upper
In [5]: g(s)
Out[5]: 'HELLO'

Is that what you're looking for?

Hi Michael,

> Out[3]: 'HELLO'
> In [4]: g = str.upper
> In [5]: g(s)
> Out[5]: 'HELLO'

That's perfect! My mistake was trying to use the method returned by
''.upper vs. str.upper.

Thank you,
Malcolm
