Python Type 2D Checklist With Code Examples

On this session, we’ll strive our hand at fixing the Python Type 2D Checklist puzzle by utilizing the pc language. The code that follows serves for instance this level.

a = [[9, 9, 2], [9, 9, 3], [9, 9, 8], [9, 9, 4], [9, 9, 1], [9, 9, 5]] b = sorted(a, key=lambda a:a[2]) #b incorporates the next arrays, sorted by their second index: [[9, 9, 1], [9, 9, 2], [9, 9, 3], [9, 9, 4], [9, 9, 5], [9, 9, 8]]

One other strategy, which incorporates a number of samples of code, could be utilised to resolve the similar drawback Python Type 2D Checklist. This answer is defined under.

knowledge = [['ABC', 12, 3, 100], ['DEF', 10, 5, 200], ['GHI', 13, 3, 1000]] knowledge.kind(key=lambda row: (row[2], row[3]), reverse=True) print(knowledge) # [['DEF', 10, 5, 200], ['GHI', 13, 3, 1000], ['ABC', 12, 3, 100]]

We have now defined easy methods to repair the Python Type 2D Checklist drawback by utilizing all kinds of examples taken from the actual world.
