knowing that with <py-config> and <py-script> can execute python code in html
However, importing own function facing error
(PY1001): Unable to install package(s) 'bread'. Reason: Can't find a pure Python 3 Wheel for package(s) 'bread'. See: https://pyodide.org/en/stable/usage/faq.html#micropip-can-t-find-a-pure-python-wheel for more information.

<py-script>
import bread.py
bread.fun_1()
</py-script>
</body>
</html>
own python script "bread.py"
def fun_1():
print("this is bread")
(pic) the result screenshot for above code
if I import my own function in another .py script is working, but do the same thing into html not works
(pic) the result that import my own function in another .py script is fine
I read through the link system recommend link, and link but I can't find out the solution myself, that I need a hand for this problem, thanks
The reason you are getting the error is that PyScript thinks you want to import a third-party package.
To import your custom modules, use [[fetch]] in your <py-config> and replace packages with files.
<py-config>
[[fetch]]
files = ["./bread.py"]
</py-config>
I'm running Windows 7, and using Google Chrome as my web browser.
This is my code:
#!/usr/bin/env python
print 'content-type: text/html\n'
print """
<!DOCTYPE html>
<html>
<head>
<title> sample </title>
</head>
<body>
"""
print 2 + 3
print """
</body>
</html>
"""
In Command Prompt, where python results in C:\Python27\python.exe, but according to this post I should use #!/usr/bin/env python instead.
When I try to run this .py code in my browser, the source code appears instead of just 5.
If someone would provide detailed instructions as to how to properly work this, I would be most grateful.
Thanks!
Okay. So of course it is not possible to run python directly in the browser but you can configure a local server to be able to run CGI scripts. Since you are on windows you could use something like a WAMP.
Try following this tutorial

I have written a game in Python using the PyGame library that I am trying to embed into an HTML page to allow me to play in a web browser.
I am attempting to do this using the JavaScript library Skulpt. I have attached a test script below that successfully outputs the print statement below.
skulpt.html
<html>
<head>
<script src="assets/skulpt/skulpt.js" type="text/javascript"></script>
</head>
<body>
<textarea id="pythonCode">
print "I am python."
</textarea><br />
<pre id="output"></pre>
<script type="text/javascript">
function outf(text) {
var mypre = document.getElementById("output");
mypre.innerHTML = mypre.innerHTML + text;
}
var code = document.getElementById("pythonCode").value;
Sk.configure({output:outf});
eval(Sk.importMainWithBody("<stdin>",false,code));
</script>
</body>
</html>
Output of skulpt.html:
The issue that I am having is that when I use my game code instead of the simple print statement shown above it produces the error seen below;
I have included all relevant images to my web servers' directory at the correct path. I am unsure of why this error is being produced. Any help would be much appreciated, thanks!
Also, here is the attached Python game code (and a live demo of the error):

You have a lot of indentation on line 1 -> remember, in python, indentation always matters. Take away all those spaces/tabs on the first line and it should run.
I am in the process of creating a Django web application that reads a URL and outputs selected data from the page. I have written the code in Python that parses the web page and it currently returns the information that I need to display in the Django app as desired.
Before I dive in I just want to confirm what I have researched is correct as I only have a limited time to complete the project.
To summarise my python code, it is in the src folder in a class called "manage.py"
I have created print statements that print the information that I need to display (I did this to ensure it was returning the correct data)
print(variable1)
print("some text" + variable2)
Can I create the Django app code in the same file, "manage.py"? (The project has already been created as a Django app in Eclipse when I started building the project)
Would I build the Django code as I've estimated below if I'm using the variables defined from the Python code above?
<!DOCTYPE>
<html>
<head>
<title>{% block title %}Title of website{% endblock %}</title>
</head>
<body>
<h1>Web page report</h1>
<h2>Summary of web page</h2>
<h3>Title of document</h3>
<p>{{variable1}}</p>
<h3>The file size of the document</h3>
<p>{"Some text" + {variable2}}</p>
</body>
</html>
Django has strict rules about where to place which information. You can not write everything into manage.py. Answering requests from the browser is for example done using view functions.
I am a behavorial scientist and usually collect data by letting participants do some tasks on a computer and record their responses (I write the programs using the pyglet wrapper PsychoPy). That is, the program runs locally and the data is stored locally.
Now I would like to know if there is a way to use Python to display a (local) website with html-forms to the user and collect the input (locally). The reason for this idea is that currently whenever I want to display checkboxes, radiobuttons, or input fields I use wxPython. This works quite well, but programming and layouting in wxPython is kind of cumbersome and I would prefer html with forms.
A requirement would be that it would need to rum without any borders, adress field, menu bar, ... The reason is that I need it in kind of fullscreen mode (I currently open a non-fullscreen pygflet window in the size of the screen to hide the desktop) so that participants can do nothing but work on the forms.
So I am looking for a way to (a) display html websites including html form above a pyglet window with no menu bar or whatsoever, (b) collect the input when clicking on the Ok button (i.e., the form is send), (c) control what is presented prior and after viewing this website, and (d) everything of this should happen locally!
My idea would be that the data is collected when participants hit the "Send away" button in the following example pic and the next page is displayed.
Update: I use windows (XP or 7).
This is a solution using Qt Webkit for rendering HTML. The default navigation request handler is wrapped by a function that checks for submitted form requests. The form uses the "get" method, so the data is included in the url of the request and can be retrieved that way. The original request is declined and you can change the content of the displayed web page as you wish.
from PyQt4 import QtGui, QtWebKit
app = QtGui.QApplication([])
view = QtWebKit.QWebView()
# intercept form submits
class MyWebPage(QtWebKit.QWebPage):
def acceptNavigationRequest(self, frame, req, nav_type):
if nav_type == QtWebKit.QWebPage.NavigationTypeFormSubmitted:
text = "<br/>\n".join(["%s: %s" % pair for pair in req.url().queryItems()])
view.setHtml(text)
return False
else:
return super(MyWebPage, self).acceptNavigationRequest(frame, req, nav_type)
view.setPage(MyWebPage())
# setup the html form
html = """
<form action="" method="get">
Like it?
<input type="radio" name="like" value="yes"/> Yes
<input type="radio" name="like" value="no" /> No
<br/><input type="text" name="text" value="Hello" />
<input type="submit" name="submit" value="Send"/>
</form>
"""
view.setHtml(html)
# run the application
view.show()
app.exec_()
As AdamKG mentioned, using a webframework would be a good choice. Since Django and similar might be an overkill here, using a micro webframework like 'flask' or 'bottle' would be a great choice.
This link demonstrates via step by step instruction how to make a simple form via a To-DO application. It assumes zero previous knowledge.
You can run it only locally also.
your want a simple solution, so just write a http server and run your simple page.
using python.BaseHTTPServer, coding a 15 line web server:
import BaseHTTPServer
class WebRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):
def do_GET(self):
if self.path == '/foo':
self.send_response(200)
self.do_something()
else:
self.send_error(404)
def do_something(self):
print 'hello world'
server = BaseHTTPServer.HTTPServer(('',80), WebRequestHandler)
server.serve_forever()
easy enough,but i suggest using some web frameworks. They are easy too.
for example, web.py. here is what u want in 50 line codes:
install web.py
make a dir with 2 files:
./
|-- app.py
`-- templates
`-- index.html
index.html
$def with (form, ret)
<html>
<head>
<title> another site </title>
</head>
<body>
<h1> hello, this is a web.py page </h1>
<form action="" method="post">
$:form.render()
</form>
<h2>$:ret</h2>
</body>
</html>
app.py logic file:
import web
### Url mappings
urls = (
'/', 'Index', )
### Templates
render = web.template.render('templates')
class Index:
form = web.form.Form(
web.form.Textbox('fav_name', web.form.notnull, description="Favorite Name:"),
web.form.Textbox('cur_name', web.form.notnull, description="Current Name:"),
web.form.Button('Send Away'),
)
def GET(self):
""" Show page """
form = self.form()
return render.index(form, "")
def POST(self):
""" handle button clicked """
form = self.form()
if not form.validates():
return render.index(form, "INPUT ERROR")
# save data by ur method, or do some task
#pyglet.save_data(form.d.fav_name, form.d.cur_name)
#pyglet.draw(some_pic)
#os.system(some_cmd)
form = self.form()
return render.index(form, "YOUR DATA SAVED")
app = web.application(urls, globals())
if __name__ == '__main__':
app.run()
run this server in your windows:
python app.py 9999
open browser: http://127.0.0.1:9999/
by the way, if ur data is only strings, u can save them in web.by by sqlite.
My suggestion would be:
Use some python server as, for example SimpleHTTPServer. It is needed because the submit button on forms sends the information to a server. There you should manage the received info some way;
Have your browser configured with one of those Kiosk extensions, which disallow even the use of Alt+F4. An example would be Open Kiosk extension for Firefox
Optionally, if you have affinity with scripts in general, you could create a script which, when executed, would at the same time run the python server AND open your html file in the browser. That would ease a lot your setup work for every subject in your group.
EDIT: I've read you need the pyglet over the browser window. That could be included in the script of step 3, using "always on top" option and absolute positioning of the pyglet (I can tell this would probably be simpler on Linux, which could be run from persistent LiveUSB - just a thought!)
EDIT (regarding the posted comment):
I think the most reliable option for output would be to disk (file or database) instead or RAM (running python object), then you read the info from file afterwards. Then, in case of a surprise (system hang, power failure), the already-entered data would be there.
The only (and most important) part I don't know HOW to do is to handle the content of the form's "submit" on the server-side. Probably some server-side script file (php, python) shoud be created and left on the server root, so the server would receive an http request containing the info, and send the info to the script, which then handles the processing and file/database storage activities.
This might be of your interest:
"The POST request method is used when the client needs to send data to the server as part of the request, such as when uploading a file or submitting a completed form." (from wikipedia on "POST(HTTP)" ENTRY)
In another link, some thoughts on using SimpleHTTPServer itself for handling POST requests:
http://islascruz.org/html/index.php/blog/show/Python%3A-Simple-HTTP-Server-on-python..html
Hope this helps.

You can combine the ease of HTML and still create native Windows applications using Flex with a Python backend.
If you are averse to Flex, a bit more - involved - but still native windows application generator is Camelot
Edit
Instead of typing it out again - I would suggest the django + flex + pyamf article on Adobe that explains it all with screenshots as well. You can replace django with flask or bottle as they are more lightweight, however the PyAMF library provides native support for django which is why it was used in the example.
PyAMF provides Action Message Format (a binary protocol to exchange object with the flash runtime) support for Python.
