How to sort nested lists into seperate lists with unique values in python?

Question

I have two variables:

unique_val = [1,2,3]
nested_list = [[\'name1\',1],[\'name2\',1],[\'name3\',3],[\'name4\',2],[\'name5\',2],[\'name6\',3]]

Answer 1

you can use list comprehension:

[[name for name, number in nested_list if number == n] for n in unique_val]

if you really want to put it in separate variable, you can do the following.

list_1, list_2, list_3 = [[name for name, number in nested_list if number == n] for n in unique_val]
