python - if i!=0 in list comprehension gives syntax error -


this question like: if/else in python's list comprehension? , simple syntax error in python if else dict comprehension . still dont understand error make here:

[i if i!=0 in range(2)]              ^        syntax error

i want entries in list non-zero sparsity.

move if end. refer the python docs entry on list comprehensions.

>>> [i in range(2) if i!=0] # or [i in range(2) if i] [1]

if looking conditional expression, @martijn pointed out,

>>> [i if i!=0 else -1 in range(2)] [-1, 1]

if want non 0 entities, filter(...) list.

>>> filter(none, [1, 2, 0, 0, 4, 5, 6]) [1, 2, 4, 5, 6]

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!
