I don't come from a software/computer science background but I love to code in Python and can generally understand why things are faster. I am really curious to know why this for loop runs faster than the dictionary comprehension. Any insights?
Is it possible to have 'optional' keys in a dict literal, rather than add them in in if statements?Like so:
Now that Python 3.7 makes order-preserving dicts officially part of the language spec instead of an implementation detail, I've been trying to wrap my head around how best to use this property. Today, I've found I needed an order preserving set and think the dictionary might do the trick.
If I have a dictionary containing lists in one or more of its values:How can I get a list of dict tuples paired by pair and iterating over c, with all else remaining constant? E.g.
