Combine lists of lists and stop once shortest parent list is exhausted-CodePudding

I have the following lists:

list_1 = [['name1', '001'], ['name2', '001'], ...]
list_2 = [['other1', '003'], ['other2', '005'], ...]

I want to combine them to the below, while stopping once either of the lists are exhausted (as per zip()):

combined_list = [['name1', '001', 'other1', '003'], ['name2', '001', 'other2', '005']]

I have tried zip() but this yields a tuple of two lists for each intended combined child list.

Is there a way to achieve this succinctly (without further looping after a zip())?

What code have you tried? I suspect you have an issue with how you've called zip().

This will add both lists together at each index, using zip():

list_1 = [['name1', '001'], ['name2', '001']]
list_2 = [['other1', '003'], ['other2', '005']]

combined_list = [x   y for x, y in zip(list_1, list_2)]

print(combined_list)

[['name1', '001', 'other1', '003'], ['name2', '001', 'other2', '005']]

Another way (Try it online!):

from operator import concat

combined_list = list(map(concat, list_1, list_2))
