Dictionary elements are accessed via keys. Oh yes, with the new code, it takes ~1 second to process 700 items and ~14 seconds to process a 2700 items dict so there's also that ^_^. Dictionaries differ from lists primarily in how elements are accessed: List elements are accessed by their position in the list, via indexing. I'd just store all the authors in a list. The easiest way to compare Python dictionaries is simply to use the same equality operator you use on other Python types. In my opinion, the use of a dict to store the initial authors is a bit overkill since you're not using any property of that. Whereas is operator checks whether both the operands refer to the same object or not. In Python, the = operator compares the values of both the operands and checks for value equality.Otherwise you compare each pair of dictionaries twice.
COMPARE TWO LIST OF DICTIONARIES PYTHON HOW TO
I want to optimize it further, and I was thinking of using Dictionary Composition, but I couldn't figure out how to get that working with my fuzzy compare logic. Answer: Optimisation 1: don't use the foreach loop you can speed it up by a factor of 2 if you only compare items of the first array with items of the second array that have at least the same index. So far I am using two dictionaries (they have the same data in both of them, and ideally I would just use one) and then using a double for loop. I want to use fuzzywuzzy to compare these author names to see if there are similar ones that I can combine. See Combining hashes/dictionaries to learn details about these options.I have a dictionary with author names as keys and values of None. Functionality of the parameters is exactly the same as in the filter combine. The examples below set recursive=true and display the differences among all six options of list_merge. It modifies the behaviour of _mergeby when the hashes to merge contain arrays/lists. Is a string, its possible values are replace (default), keep, append, prepend, append_rp or prepend_rp. Note: It does not depend on the value of the hash_behaviour setting in ansible.cfg. Should the _mergeby recursively merge nested hashes. This is available since community.general 4.4.0. These parameters are only supported when used with ansible-base 2.10 or ansible-core, but not with Ansible 2.9. The filter also accepts two optional parameters: recursive and list_merge.
