One of the things which I miss while writing programs in C is a dictionary data structure. What's the most convenient way to implement one in C?

I am not looking for performance, but ease of coding... Search a list of dictionaries in Python - Stack Overflow. Building on this, 64 I tested various methods to go through a list of dictionaries and return the dictionaries where key x has a certain value. Results: Speed: list comprehension > generator expression >> normal list iteration >>> filter. All scale linear with the number of dicts in the list (10x list size -> 10x time).

Iterating over dictionaries using 'for' loops - Stack Overflow. What is the true difference between a dictionary and a hash table?. I've always used dictionaries.

I write in Python.A dictionary is a data structure that maps keys to values. This perspective suggests that, a hash table is a data structure that maps keys to values by taking the hash value of the key (by applying some hash function to it) and mapping that to a bucket where one or more values are stored. IMO this is analogous to asking the difference between a list and a linked list. python - Comparing two dictionaries and checking how many (key, value ....

4 In PyUnit there's a method which compares dictionaries beautifully. I tested it using the following two dictionaries, and it does exactly what you're looking for. How do I merge two dictionaries in a single expression in Python?. Assuming two dictionaries of dictionaries, one might recursively merge them in a single function, but you should be careful not to modify the dictionaries from either source, and the surest way to avoid that is to make a copy when assigning values. As keys must be hashable and are usually therefore immutable, it is pointless to copy them:
