I have a requirement where i have to use my python project into WordPress web page, where i ask user for input in one tab than execute it and gives back the result on display on the web-page.
I found one plugin for the same namely: "Create With Code".
It worked pretty well, only challenge was to expose my code into third party website which i can not do.
Now i have started to create my own custom plugin to do the same.
Could anyone suggest whether i am on a right track or is there any other secure straightforward way to achieve that.

I have written an application in python to collect data from a javascript form and returned the processed text. It is based entirely off of the code here (but a lot more complex, so I have to use python for this).

I need to use this in wordpress (since that's what runs my site) and I honestly have no idea how to pull this off. Webpy can run with Apache CGI, but the documentation (http://webpy.org/cookbook/cgi-apache) is only clear if one wants to navigate directly to the python app as its own page.
I'm hoping someone here has expertise in how to embed this all within a Wordpress page/post?
Thanks!!
As far as I know, there is no native way to run Python code inside a WordPress site just like php. In fact, if you are not doing anything unique to Python, I would suggest you to use php, which supports regular expression and can be used in WordPress by installing the plugin "Insert PHP".
If you really want to use Python, then you need an API endpoint where you connect the function to your website. You would have to look into Azure Function App/AWS lambda on which you write a function app to work as a backend. Then whenever someone request your website, your website would do an HTTP request to that API.
Can you explain what exactly you want to do on your website?
I need to develop a simple login page using Python language with two fields and a button, like:
Username, Password, Login
I know there are some beautiful Python frameworks like
Django, Grok, WebPy, TurboGears
which support web development using Python, but mine is a basic requirement consisting of only 3 screens (pages):
1st page - Login page (Redirects to 2nd page when login button is clicked)
2nd page - Page with records in the form of a list, with an option for adding new records (Redirects to 3rd page when "Add Records" button is clicked)
3rd page - Page with fields, which are saved as records for the list on 2nd page (After entering details and clicking Submit)
So, I have decided to develop the above functionality using Python without using any framework, so that I can have flexibility as well as write my own code.
Is it possible to create a login page using Python without using a framework?
I haven't worked on web services and don't know the basics of web development in Python.
If possible, can you provide me an example on how to create a login page using Python and achieve the functionality described above?
Firstly, it's good to learn how to do things without the frameworks, but if you're doing this for anything but educational purposes it's most likely a mistake to say "my requirements are too simple to bother with frameworks." What you describe is on the simpler end of the spectrum, but already I can see some complications you're probably glossing over.
Anyway, to implement your 3 pages, you will need:
a web server
2 static HTML files
python handlers for GET on 2nd Page, POST from 1st and 3rd Page
storage (either flat file or database)
Look at A Simple Python CGI Server Tutorial to get started, and there are more details at TutorialsPoint: Python - CGI Programming.
Your HTML forms just need to have method="POST" and action set to the URL you're serving from python for each form. Your POST handlers should do what they need to do and then serve a 302 redirect.
If you don't know the basics of python web development, you're going to have your hands full and should probably start with a single user flat-file system. Maybe you can even get away with storing that in memory for now. Then if/when that stops doing it for you, try sqlite. Configuring web servers is a pain, too, so if you can just stick with BaseHTTPServer.
Finally, load your records in another python endpoint, make some HTML for each, slap it in a big string with surrounding HTML, and serve that puppy.
You requirement is very trivial. Though people may suggest micro frameworks like flask, bottle I would say you should try Django and have a look at Django Admin Panel. I think it's possible for you to meet your requirement using the Django admin feature.

Have a look at this http://docs.python.org/howto/webservers.html
Without a framework and if you don't want to mess with CGI you can take a look at http://webob.org/ .
I want to create a special wiki page on my local Redmine server. It should contain an inventory of some executables from my server. My goal is a script which scans certain folders on my server for these files and put them (with some additional information) in a nice Redmine wiki page.
My first thought was to traverse my server's file system with a simple batch file and to create a SQL expression for putting the results directly into the underlying mySQL database (which contains Redmine's wiki pages). But I consider this too risky and too error-prone.
Then I had the idea to use a script language like python (which I always wanted to learn) to retrieve the information and send it back to the Redmine server, like a web browser would do. This should be a much safer way. But this doesn't seems to be an easy beginner's task when just starting with python - I fail to authenticate myself on the Redmine server.
My last idea was to create a HTML page with python, which could be displayed within a Redmine wiki page with the plugin 'Redmine Wiki Extensions'. But I consider this only as a solution light, because it's not very elegant.
So what I seek is either a new idea to solve this problem or some clues on how to do a proper authentification with python on my Redmine server - maybe I could use a cookie for easier authentification...
I'm not familiar with redmine, but if you are looking for something like having a script that performs some actions the same way you would do in a browser, then mechanize is a library that might be helpful for you unless there's some javascript involved. In that case, then I'd look into something like windmill or selenium to let you drive the web browser.
However, please note using web scraping is also error-prone since any change in the design of the web pages involved might break your scripts.
Regarding the option of using an API as pointed out by the comment from AdamKG, that would be a good option, since there's a REST API that you can use from python if you like. Unfortunately, I don't see anything to let you do what you're looking for and it seems it hasn't yet reached the stable status yet. Anyway, as I said, it's still a good option to consider in the future.
I am curious if there might be a way to dynamically alter source from a web page automatically.
For instance, I know the firebug plugin for Firefox allows the capability to modify the source and see the reaction in real-time. So, say I want to login to a particular form. Could I alter this dynamic source with a login name and password and enter the website in question via some automated script? If not, are there any potential alternatives to this approach that may fair better?
Thanks.
If you want something which can automate IE browser, what I can recommend to you is: Watir and WatiN. Watir is developed in ruby while WatiN is developed in c#. They are both quite powerful, more than enough to meet your requirements.
If you have to use Python script. then I would recommend C# + WatiN + IronPython. You can write python scripts to call WatiN's dll. Please note that, IronPython is not the same as Python, it is based on microsoft's .net framework. Currently I don't know any pure python product which can do the same as WatiN and Watir.
If you want to login to a website automatically you don't need to edit the source, you need to interact with the webserver. Try curl and use it to submit login details and fetch the resulting web page.
for firefox automation, I recommend chickenfoot to you. It can meet your needs:
alter this dynamic source with a login
name and password and enter the
website in question via some automated
script
But chechenfoot only supports up to firefox 3. If you want to support the newest version of firefox, you might have to get the source code and compile it yourself.
If you can use Javascript, try:
document.write("HTML CODE HERE");
But if you need in Python, I think you can use REPLACE in the HTML Source Code.
I want to cache a webpage as an image upon a user request, but I don't know where to start with this.
I'm developing on App Engine with python.
Here's a good library for capturing a webpage as a png image:
http://github.com/AdamN/python-webkit2png
One way is to use a web service such as thumbalizr since a lot of the programs for this type of thing aren't always install-able on appengine (because they use C++, etc). Other options include girafa and browsershots.
There are websites that to this for you. Google is your friend. If you build a script around them, you have what you need. As a demonstration, see http://webshots.velocitysc.com/sandbox/.
There are also downloadable programs that do it, such as the one at http://download.cnet.com/Advanced-Website-to-Image-JPG-BMP-Converter-Free/3000-2094_4-10900902.html. These are just examples; google a while and you'll find better implementations.
If you want to do it yourself, you basically need to duplicate a web browser (the HTML rendering part, anyway), which is unrealistic, or use a preexisting rendering engine like webkit as Zach suggests. If I were you, I would forget about doing it myself and use a preexisting web service, unless this is going to be the core of your application.
