looking for a fast multi process shared dict
cross-posted from: https://feddit.de/post/248196 > I have lots of multiprocessing processes which have to add to and search in a dict. Deletion of values is not needed. > > Atm I am using multiprocessing.Manager() and > > `dict = manager.dict()` > > This works pretty well, but I think that the manager is a huge bottleneck here. Any ideas? It has to run on older Python 3 versions, otherwise I would use this cool thing I found: https://github.com/ronny-rentner/UltraDict

SimpleHTTPServer is a python module which allows you to instantly create a web server or serve your files in a snap. The main advantage of python’s SimpleHTTPServer is you don’t need to install anything since you have python interpreter installed. You don’t have to worry about python interpreter because almost all Linux distributions, python interpreter come handy by default. You also can use SimpleHTTPServer as a file sharing method. You just have to enable the module within the location of your shareable files are located. The article below guides you on how to set up and use it.

Why do tuples and lists both need to exist?
The only differences are that tuples are immutable and that lists have extra methods. Is there ever a strong need for list-type data to be immutable? Evough to justify a whole extra data-type in the language? Should they release a python 4 with it removed? The only thing I can think of is as a default function parameter. This function is okay: ``` def dothings(a=(1,2)): print(a) a = (a[0], 3) ``` But this function misbehaves the second time it is called: ``` def dothings(a=[1,2]): print(a) a[1] = 3 ``` But IMO the "mutable arguments" thing is another bug to be fixed in a hypothetical python 4. And even in python 3 you just write the function the recommended way, so there is not such a big problem. ``` def dothings(a=None): if a is None: a = [1, 2] print(a) a[1] = 3 ``` The Python devs are clever guys though. There must be some really important reason to maintain both types?
