k-combinations in Python 3.x -


what efficient way generate k-tuples k-combinations given python set? there appropriate built-in function? tells me should possible two-line loop.

p.s. did conduct search , found various entries topic "combinations lists, etc in python", proposed solutions seem rather 'un-python'. hoping mind-blowing, idiomatic python expression.

itertools has of types of functions:

import itertools  combination in itertools.combinations(iterable, k):     print(combination)

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
