Error running Python script from Applescript

Question

Why doesn't this work?

Applescript:

set script_path to "$HOME/Desktop"
do shell script "python & script_path & hello_world.py"

Python script:

#!/usr/bin/env python
print "Content-Type: text/html"
print
print """\
<html>
 <head>
  <title>Python - Hello World</title>
 </head>
 <body>
  Hello World
 </body>
</html>

"""

Errors:

tell current application do shell script "python & script_path & hello_world.py" --> error "sh: script_path: command not found sh: hello_world.py: command not found" number 127 Result: error "sh: script_path: command not found sh: hello_world.py: command not found" number 127

Is that really how you concatenate in AppleScript? I'd guess that that runs python in the background, script_path in the background, and hello_world.py. (The latter two don't exist.) — Ry-

The ampersands concatenate the string literals and variable substitutions. Like so:

set script_path to "$HOME/Desktop"
do shell script "python " & script_path & "/hello_world.py"

You also need a slash before hello_world.py or at the end of $HOME/Desktop. The example above shows it before hello_world.py.
