Thanks for your reply.
The output should 1) show manually selected python code and comments
(whatever I think is important), 2) show selected results (final and
intermediate) and 3) *not* show python code that for someone only
interested in the calculation and the results (and probably not
knowing python) would just be "noise" (e. g. "import"-statements,
actual "print()"-functions, etc.).
Here is my second attempt. This version introduces what I might
optimistically call a very simple markup language in the code.
Printing of source can selectively be turned on and off by inserting
lines beginning with "## Ignore" or "## Show" into the source file.
------------------------------
## Ignore
from __future__ import with_statement
import sys
def print_selected_source():
is_printing = True
with open(sys.argv[0]) as file:
for line in file:
if line.startswith("## Ignore"):
is_printing = False
elif line.startswith("## Show"):
is_printing = True
elif is_printing:
print line,
## Show
a = 1
b = 2
c = 3
result = a + b
## Ignore
print_selected_source()
print("result =\t", result)
print("result + c =\t", result + c)
------------------------------
Is this getting closer?

How about simply importing the file with the calculations? Printing the
imported file is quite straightforward, and except for maybe skipping
the import lines that may be at the top (eg. import math), the rest of
the file could be meaningful for the end user.
That has the advantage that it's easy to have multiple "notepads", but
only one set of code that runs them.
