Pythonic way to unpack an iterator inside of a list

Question

I\'m trying to figure out what is the pythonic way to unpack an iterator inside of a list.

For example:

my_iterator = zip([1, 2, 3, 4], [1, 2, 3, 4]         


        

Answer 1

This might be a repeat of Fastest way to convert an iterator to a list, but your question is a bit different since you ask which is the most Pythonic. The accepted answer is list(my_iterator) over [e for e in my_iterator] because the prior runs in C under the hood. One commenter suggests [*my_iterator] is faster than list(my_iterator), so you might want to test that. My general vote is that they are all equally Pythonic, so I'd go with the faster of the two for your use case. It's also possible that the older answer is out of date.
