Is it possible to redirect the python output to web by using the redirecting command? I know that we can redirect the output like this
import sys
sys.stdout = open('file', 'w')
print 'test'
or
In terminal like this
$ python foo.py > file
I heard the 'Django' and 'Flask' like web framework can do the trick. I wonder whether by using a simple command like sys.stdout can redirect the output to web?
I know we can use HttpResponseInstance['headername'] = 'headervalue' to add header to http response. But in this way, I have to rewrite all the generic view I am using, which makes much more work.
Is there a convenient way to add header to responses, like a callback for responses, or a url decorator?

I am using Polymer 1.0, and I'm having a problem retrieving and inserting into the dom and showing. I can get the HTML "li" to print to the console, but I am unable to get polymer to render the HTML.
<example-app appjs="appJsFile.js">
<ul id="content">
//I want Content Here from Polymer
</ul>
</example-app>
appJsFile.js gets imported into "example-app". I have a function for this:
for(var i in this.listData){
var _ele = parent.document.createElement('li');
_ele.innerHTML = this.listData[i].listDataName;
return _ele;
}
Any ideas?
Why is it acceptable for Gmail to have that loading delay of almost 6 seconds everytime that you load gmail.com on a dekstop?
Yahoo or Outlook doesn't have this problem at all.
