Passing a variable name as a parameter to a function in Python

I want to use a function that accepts kwargs, but the argument name is being retrieved from a separate process and is unknown before hand.

For example:

param = 'desired_param'

some_function(desired_param=5)

The problem is that I don't know the content of the param and so have to somehow pass it to some_function.

Is it possible to pass the content of the param to the function with a value?

some_function is not something I defined, so I don't have any control over it.

Use keyword expansion:

param = 'desired_param'
d = {param:5}
some_function(**d)

Or even shorter:

param = 'desired_param'
some_function(**{param:5})
