Python for WEB-page !?

[Ionut Predoiu]

Good afternoon,

I am a beginner in programming language.
I want to know what version of Python I must to learn to use, beside of basic language, because I want to integrate in my site 1 page in which users to can made calculus based on my formulas already write behind (the users will only complete some field, and after push "Calculate" button will see the results in form of: table, graphic, and so on ...).
Please take into account that behind will be more mathematical equations/formulas, so the speed I think must be take into account.

I waiting with higher interest your feedback.

Thanks to all members of community for support and advice.
Keep in touch.
Kind regards.

Building a web site can be done with Flask, Django, aiohttp, or a
number of other frameworks. Generating graphs can be done with
matplotlib. Speed won't be a problem - a computer can do a LOT of
mathematical calculations in the time it takes to request something
over the internet.

Have fun exploring!

I recommend starting with Python 3, I also use it (3.5.2) for my Django
projects - Speedy Net and Speedy Match.

Consider PyPi. I never used it, but they say, it is faster than usual
CPython interpreter.

Really? I'd strongly contrast the Python Package Index https://pypi.python.org/pypi with the Python implementation pypy at http://pypy.org/ :)

With respect, I don't think it's appropriate to direct a python beginner
to PyPi. Far better to direct him to the relevant resources (like
Django) and focus him on the standard Python interpreter, hopefully
version 3.

Besides that, there's the old expression. Premature optimization is the
root of all evil. Until Python is shown to be too slow for a given
task, it's premature to think about speedups like Cython or even PyPi.

While Python can do that, using a web framework to process HTTP requests
and generate HTML to display in the browser, I don't believe Python is
the appropriate language for the task at hand. Most web sites that do
interactive formula calculations like you describe do it all in the
browser using Javascript. No need to have a web server do all that
heavy lifting at all. A simple html file would contain everything you need.

Even if you want to use Python to generate the web page and process
events, you'll still have to master Javascript at some point to make the
webpages more interactive.

Good morning,

Thanks to all for feedback and advice.
Because I am a beginner I will read more about versions of Python recommended by you.

On the other side I am interested to know if exist some sites which have develop platform where can be use for free Python from browsers, without have it installed on PC/laptop. As beginner I want to practice from everywhere.

I waiting with higher interest your feedback.

Thanks to all members of community for support and advice.
Keep in touch.
Kind regards.

There's a website called Python Tutor where you can write Python
programs and it will show you the structures built in memory as it
executes. It's very useful for seeing how recursive functions work, or
any function or class you call. It will also work for simple programs
and it has an output console you can print to. (Well, it's more like a
print window, but it works.) Very good for beginners, I used it all the
time when I was first learning, and I still use it for recursive
functions, since PyCharm doesn't step through recursion in a clear way.

Good afternoon,

Thank you for advice and promptitude in answer.

Keep in touch for further questions.

There are a few implementations of Python that generate code that can
run the browser. I'm currently using brython and its significantly
easier than struggling with JavaScript. It's not perfect by any means,
it has its own quirks and bugs but the developer is very responsive, the
product is getting better every month and I like to see the Python
community give it a bit more love

It might be worth while to look at web2py (http://web2py.com).

Here is a good tutorial: http://killer-web-development.com/
