Python initialize multiple variables to the same initial value

I agree with the other answers but would like to explain the important point here.

None object is singleton object. How many times you assign None object to a variable, same object is used. So

x = None
y = None

is equal to

x = y = None

but you should not do the same thing with any other object in python. For example,

x = {}  # each time a dict object is created
y = {}

is not equal to

x = y = {}  # same dict object assigned to x ,y. We should not do this.

(
    details,
    producy_base,
    product_identity,
    category_string,
    store_id,
    image_hash,
    image_link_mask,
    results,
) = (None, None, None, None, None, None, None, None)

abort = False
data = {}

That's how I do.

First of all I would advice you not to do this. It's unreadable and un-Pythonic. However you can reduce the number of lines with something like:

details, product_base, product_identity, category_string, store_id, image_hash, image_link_mask, results = [None] * 8
abort = False
data = {}
