I have a WordPress install for a personal blog and I'm gradually porting all of the little web bits I have written over the years to pages on the blog.
One such page is .py which is a simple python script that returns a list of words - I'd like to embedd that behavior within a wordpress page - could someone point me in the right direction for the easyist way of running a spot of python within wordpress?
EDIT - following the wonderful answer below, I have got a lot futher... but unfortunately still not quite there...
I have python that executes on server...
projecttoomanycooks server [~/public_html/joereddington/wp-content/plugins]#./hello.py
Hello World!
and it's in the same directory as the activated plugin...
The python code... which has the following code...
#!/usr/bin/python
print("Hello World!")
The php:
<?php
/**

- 1 If it's a very simple script, I think I would just rewrite it in PHP as a WordPress plugin/template ;-) But in some cases people use iframes to embed external pages. – birgire Commented Oct 27, 2013 at 13:29
- iframe it directly? :] – Jesse Commented Oct 27, 2013 at 13:36
- Is this just an accident, or is your python code really mixed with PHP? – fuxia ♦ Commented Nov 5, 2013 at 17:01
- I pasted the terminal trace, with the files being displayed by the 'more' command... will tidy up a little... – Joe Commented Nov 5, 2013 at 21:42

Reset to default 26You can use popen() to read or write to a Python script (this works with any other language too). If you need interaction (passing variables) use proc_open().
A simple example to print Hello World! in a WordPress plugin
Create the plugin, register a shortcode:
<?php # -*- coding: utf-8 -*-
/* Plugin Name: Python embedded */
add_shortcode( 'python', 'embed_python' );
function embed_python( $attributes )
{
$data = shortcode_atts(
[
'file' => 'hello.py'
],
$attributes
);
$handle = popen( __DIR__ . '/' . $data['file'], 'r' );
$read = '';
while ( ! feof( $handle ) )
{
$read .= fread( $handle, 2096 );
}
pclose( $handle );
return $read;
}
Now you can use that shortcode in the post editor with [python] or [python file="filename.py"].
Put the Python scripts you want to use into the same directory as the plugin file. You can also put them into a directory and adjust the path in the shortcode handler.
Now create a complex Python script like this:
print("Hello World!")
And that’s all. Use the shortcode, and get this output:
I followed the example script from the first answer, but was getting no output or errors.
I changed this line:
$handle = popen( __DIR__ . '/' . $data['file'], 'r' );
to this:
$handle = popen( __DIR__ . '/' . $data['file'] . ' 2>&1', 'r' );
and then got a "permission denied" message.
On the console, I ran
chmod 777 hello.py
refreshed the page, and everything worked perfectly.
This may be the issue Joe was seeing above. I don't have enough rep to make a comment, sorry. Hope this helps someone.
Here's a little script that uses proc_open as noted above, to sent one simple text variable to a python script:
add_shortcode( 'execute_python', 'execute_python_with_argv' );
function execute_python_with_argv( $attributes ){
$description = array (
0 => array("pipe", "r"), // stdin
1 => array("pipe", "w"), // stdout
2 => array("pipe", "w") // stderr
);
$application_system = "python ";
$application_path .= plugin_dir_path( __FILE__ );
$application_name .= "hello.py";
$separator = " ";
$application = $application_system.$application_path.$application_name.$separator;
$argv1 = '"output to receive back from python script"';
$pipes = array();
$proc = proc_open ( $application.$argv1 , $description , $pipes );
//echo proc_get_status($proc)['pid'];
if (is_resource ( $proc ))
{
echo "Stdout : " . stream_get_contents ( $pipes [1] ); //Reading stdout buffer
fclose ( $pipes [1] ); //Closing stdout buffer
fclose ( $pipes [2] ); //Closing stderr buffer
$return_value = proc_close($proc);
echo "<br/>command returned: $return_value<br/>";
}
$application_test = glitch_player_DIR.$application_name;
echo "<br/>Is ".$application_test." executable? ".is_executable($application_test)." ";
echo "readable? ".is_readable($application_test)." ";
echo "writable? ".is_writable($application_test)." ";
} //EOF main/shortcode function
Added a few tests as the bottom to see if the python file is rwx. I think a better way to send the argv would be using fwrite, but it wasn't working for me following this tutorial.
Here is the python script I used. As noted in comments above, something like #!/usr/bin/env python may be necessary, depending on server.
#!/usr/bin/env python
from sys import argv
script, what_he_said = argv
print "This is what you submitted: %s \n \n Isn't that amazing, man? " % what_he_said
