Does python have the ability to create dynamic keywords?
For example:
qset.filter(min_price__usd__range=(min_price, max_price)) I want to be able to change the usd part based on a selected currency.

Keyword arguments (or named arguments) are values that, when passed into a function, are identifiable by specific parameter names. A keyword argument is preceded by a parameter and the assignment operator, = . Keyword arguments can be likened to dictionaries in that they map a value to a keyword.
Python has *args which allow us to pass the variable number of non keyword arguments to function. In the function, we should use an asterisk * before the parameter name to pass variable length arguments.
5 Types of Arguments in Python Function Definition:positional arguments. arbitrary positional arguments. arbitrary keyword arguments.
Python Code can be dynamically imported and classes can be dynamically created at run-time. Classes can be dynamically created using the type() function in Python. The type() function is used to return the type of the object. Syntax: type(object) The above syntax returns the type of object.
Yes, It does. Use **kwargs in a function definition.
Example:
def f(**kwargs): print kwargs.keys() f(a=2, b="b") # -> ['a', 'b'] f(**{'d'+'e': 1}) # -> ['de'] But why do you need that?

If I understand what you're asking correctly,
qset.filter(**{ 'min_price_' + selected_currency + '_range' : (min_price, max_price)}) does what you need.
