Automation P-I-D
I mentioned some time ago about a program to calculate PID constants for tuning controllers, follow the link to its online version algorithm for anyone interested http://pastebin.com/wAqZmVnR I thank you for the help I received from many here on the list. ;D -- https://mail.python.org/mailman/listinfo/python-list
Web framework
I'm thinking of porting a Python application that uses numpy for web, basically would like to upload a user-defined data, perform the calculations with numpy and plot charts with the general structure of a site such as a blog for example, I have studied a bit of django and web2py, but I wonder if there is some better framework? or how to choose a particular framework over another? Since now, thanks -- https://mail.python.org/mailman/listinfo/python-list
Re: Automation
Thanks for all the help, I finished the program, follow the download link and a brief explanation of the same (in Portuguese, my native language), I apologize again for my bad english and any inconvenience that I have generated. http://mundodacana.blogspot.com.br/2013/11/programa-para-calculo-de-constantes-pid.html Python commands :D -- https://mail.python.org/mailman/listinfo/python-list

print('Content-type: text/html\n')# hdr plus blank line
print('Reply Page')# html reply page
if not 'user' in form:
print('Who are you?')
else:
print('Hello %s!' %
cgi.escape(form['user'].value))
application = tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
application.listen()
tornado.ioloop.IOLoop.instance().start()
*In the terminal have these outputs:*
python test.py
Content-type: text/html
Reply Page

IDE for GUI Designer
Guys, is this, I wonder if there is an IDE with native support for the development of GUI's such as Netbeans with Swing, Visual Basic, etc., already tested the Boa Constructor, and PyQt, but did not like what I'm looking for is an IDE "all in one", ie power encode and draw the screens of the program, someone indicates some?, but what I would like to know everything together with an IDE: Coding + GUI (via visual elements) without the need to import or export anything, like so: I want a button, I click and drag it to a window, give two clicks and encode their actions, understand? Thanks for all. -- http://mail.python.org/mailman/listinfo/python-list

Tkinter
I need to create a button and a text box follows the text box to enter a number, and this number is expected to create the same screen text boxes, and these text boxes need to be referenced, ie if I enter 30 in the first text box and click the button to be created 30 text boxes so that I can then " call" each of the boxes, eg box1, box2, box3, etc. .. . This all-in Tkinter. I thank you all for understanding and help. -- http://mail.python.org/mailman/listinfo/python-list
