Python Basics: How can i set two function parameters in equations?

I have a basic question on python functions and parameters

Given this function:

def findArticleWithAttr(tableattrib, user_url_input):
    articles = Something.objects.filter(tableattrib=user_url_input)

I call the function with:

findArticleWithAttr(attribute1, userinput1)

tableattrib is not set by findArticleWithAttr attribute1 and just takes the latter (userinput1) parameter and replaces it.

How can i make python set both parameters in the equation?

You could use the ** double-splat operator:

def findArticleWithAttr(tableattrib, user_url_input):
    articles = Something.objects.filter(**{tableattrib : user_url_input})

Basically, the ** operator makes

func(**{'foo' : 'bar'})

equivalent to

func(foo = 'bar')

It allows you to call a function with arbitrary keyword arguments.
