Merging a list of lists

Question

How do I merge a list of lists?

[[\'A\', \'B\', \'C\'], [\'D\', \'E\', \'F\'], [\'G\', \'H\', \'I\']]

into

[\'A\', \'B\', \         


        

Answer 1

To concatenate the lists, you can use sum

values = sum([['A', 'B', 'C'], ['D', 'E', 'F'], ['G', 'H', 'I']], [])

To add the HTML tags, you can use a list comprehension.

html_values = ['' + i + '' for i in values]
