Python 2 and Python 3 i is the key, so you would just need to use it: Python 3 d.items() returns the iterator; to get a list, you need to pass the iterator to list() yourself. Python 2 You can get an iterator that contains both keys and values. d.items() returns a list of (key, … Read more
This is a great module that someone created. I’ve used it several times. http://code.activestate.com/recipes/410469-xml-as-dictionary/ Here is the code from the website just in case the link goes bad. Example usage: //Or, if you want to use an XML string:
I am relatively new to Java, and often find that I need to sort a Map<Key, Value> on the values. Since the values are not unique, I find myself converting the keySet into an array, and sorting that array through array sort with a custom comparator that sorts on the value associated with the key. … Read more
Clearly you’re passing in d.keys() to your shuffle function. Probably this was written with python2.x (when d.keys() returned a list). With python3.x, d.keys() returns a dict_keys object which behaves a lot more like a set than a list. As such, it can’t be indexed. The solution is to pass list(d.keys()) (or simply list(d)) to shuffle.
There is no such function; the easiest way to do this is to use a dict comprehension: In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn’t introduced until python 2.7. Note that there is no such method on lists either; you’d have to use a list comprehension or the map() function. As … Read more
Two terms for the same thing: “Map” is used by Java, C++ “Dictionary” is used by .Net, Python “Associative array” is used by PHP “Map” is the correct mathematical term, but it is avoided because it has a separate meaning in functional programming. Some languages use still other terms (“Object” in Javascript, “Hash” in Ruby, “Table” in Lua), but those all … Read more
It really does seem like you’re overcomplicating this issue. You can just use the indexer ([]) of the Dictionary class along with the .ContainsKey() method. If you use something like this: You should achieve the effect that you want.
Python has the pickle module just for this kind of thing. These functions are all that you need for saving and loading almost any object: In order to save collections of Python there is the shelve module.
If you want to know how many values match in both the dictionaries, you should have said that 🙂 Maybe something like this:
This is how I did it and it works: It gives you a list of n empty dictionaries.
