These are some tricks in python that should help with speed-based programming competitions, like ProgComp. The map function takes python tricks pdf download arguments.
The second one is a list. The first one is a function. Map passes every element in the list into the function, and returns each result individually. Actually, it gives us a generator. We then call list on the generator to turn it back into a list. If you have a fixed number of integers on one line, we can 'unpack' these into their own python tricks pdf download. The map function is also useful for other operations. We can pass a lambda function to it in order to do other sorts of processing.
The zip function zips multiple iterables togeather. While this sounds a bit odd, it can be used to great effect. Warning: If the sequences are of different sizes, they will all be truncated to the length of the shortest one. The syntax for a splice is sequence[start : stop : step]. TODO: Actually write things here if people don't know about splicing, python tricks pdf download. If index is not specified, the last thing in the list will be removed.
Note that you should not use this to implement a queue if you can help it. This will only remove the first occurrence of the value. If the value does not exist, an error will be thrown. You can 'safely' remove all occurrences using a list comprehension. If anyone has a better way of doing this, please tell me. We can convert the list to a setwhich doesn't allow multiple occurrences of the same value, and then convert it back again, python tricks pdf download. If you need a queue, you should use collections.
It works like a list, except it has two extra functions, popleft and appendleft for fast insertion at the beginning. The defaultdict is an extremely usefull structure.
It is the same as a dictionary, except all keys are populated by a default value. Pass a function to the dictionary's constructor. The function should return the default value. Extensive details here. Itertools is magic or something. It will save a lot of time with anything that requires computing combinations or permutations. Itertools official documentation.
There's some extra stuff in the docs that's not covered here. You should at least read through the list of available functions. Skip to content. Instantly share code, notes, and snippets. Code Revisions 7 Stars 1 Forks 1. Embed What would you like to do? Embed Embed this gist in your website.
