Is there a way to declare variables in list creation?
I'd like to create and assign new String variables when I create my list. I'd like to do something like:
l = [first = "first", second = "second"]
Is something like this possible?
python python-3.x list declaration

Don't you want a dictionary instead?

What do you want to achieve by doing this? Assigning in separate statements is perfectly fine and being obsessed with one-liners usually leads to code that is hard to read and understand.

Not clean from your question, but suggest you read Why you don't want to dynamically create variables.

That syntax is not allowed. Instead you can do the following (You can name it whatever you like, in-place unpacking, iterable unpacking, etc.):
first, second = ["first", "second"]
However, very similar to what you want to do you can create a dictionary as following which also seems more efficient and Pythonic for your goal here.
In [1]: d = dict(first_k = "first", second_k = "second")
In [2]: d['first_k']
Out[2]: 'first'
In [3]: d.keys()
Out[3]: dict_keys(['first_k', 'second_k'])
In [4]: d.values()
Out[4]: dict_values(['first', 'second'])
