Create a tuple from a string and a list of strings
53,383
Solution 1
I can't speak for performance, but this is definitely the simplest I can think of:
my_tuple = tuple([my_string] + my_list)
Solution 2
The straightforward way is simply my_tuple = tuple( my_list + [my_string] )
. I would certainly start with that and see if the performance is acceptable before trying to figure out any crazy ways of subverting the normal system for speed.

I need to combine a string along with a list of strings into a tuple so I can use it as a dictionary key. This is going to be in an inner loop so speed is important.
The list will be small (usually 1, but occasionally 2 or 3 items).
What is the fastest way to do this?
Before:
my_string == "foo" my_list == ["bar", "baz", "qux", "etc"]
After:
my_tuple == ("foo", "bar", "baz", "qux", "etc")
(Note:
my_list
must not be altered itself).
