How to create objects on the fly in python?

Question

How do I create objects on the fly in Python? I often want to pass information to my Django templates which is formatted like this:

{\'test\': [a1, a2, b2],          


        

Answer 1

You can use built-in type function:

testobj = type('testclass', (object,), 
                 {'test':[a1,a2,b2], 'test2':'something else', 'test3':1})()

But in this specific case (data object for Django templates), you should use @Xion's solution.

Answer 2

for the sake of completeness, there is also recordclass:

from recordclass import recordclass
Test = recordclass('Test', ['test', 'test1', 'test2'])
foo = Test(test=['a1','a2','b2'], test1='someting else', test2=1)

print(foo.test)
.. ['a1', 'a2', 'b2']
