I have lists such as:
list_1 = []
list_2 = []
list_3 = []
I want to put them all into a list where the list names are strings
list_final = ["list_1", "list_2", "list_3"]
Is there a simple way to do this?

Using a dict
my_lists = {
"list_1": [],
"list_2": [],
"list_3": [],
}
The "names" ("keys" in terms of dict) are available as my_lists.keys() or by iterating my_lists:
for list_name in my_lists:
print(list_name)
Or, for literally the sample given in the question:
list_final = list(my_lists)

The below shall work..
list = [list_1, list_2, list_3]
names=['list_1', 'list_2', 'list_3']
list_final = dict(zip(names,list))
print(list_final)
print(list_final['list_1'])
print(list_final['list_2'])
print(list_final['list_3'])
If you want to just put the names in the final list, you can do this:
list_final_names=[]
for name in list_final:
list_final_names.append(name)
print(list_final_names)

As per the question, a list of names (i.e.
names) is the desired result, not the initial setup.
dicttype: docs.python.org/3/tutorial/datastructures.html#dictionaries[list_1, list_2, list_3]is not "a list where the list names are strings". Is your desired output["list_1", "list_2", "list_3"]? Are you looking for a mapping from name to list, i.e.{"list_1": list_1, "list_2": list_2, "list_3": list_3}?
