Sorting and Grouping Nested Lists in Python

Question

I have the following data structure (a list of lists)

[
 [\'4\', \'21\', \'1\', \'14\', \'2008-10-24 15:42:58\'], 
 [\'3\', \'22\', \'4\', \'2somename\', \'2         


        

Answer 1

For part (2), with x being your array, I think you want,

[y for y in x if y[3] == '2somename']

Which will return a list of just your data lists that have a fourth value being '2somename'... Although it seems Kamil is giving you the best advice with going for SQL...
