I wish I could understand the following behaviour:
1. This works as I expect it to work:
def f():
i = 1
print(locals())
exec('y = i; print(y); print(locals())')
print(locals())
exec('y *= 2')
print('ok:', eval('y'))
f()
{'i': 1}
1
{'i': 1, 'y': 1}
{'i': 1, 'y': 1}
ok: 2

Here is my test program:
''' generic test '''
import functools
import inspect
def f():
'''I am f'''
pass
g = functools.partial(f)
g.__doc__ = '''I am g'''
g.__name__ = 'g'
def partial(func, *args, **keywords):

newkeywords = keywords.copy()
Yet another sphinx question. I am a beginner here.
I can't make sphinx to recognize the following (abbreviated) code:
'''
module description
:func:`~pipe` and :func:`~spipe` read data passed by LDM's `pqact`.
'''
def _pipe(f, *args):
'''doc string'''
pass
def _get_msg_spipe():
'
What graphics editor would you recommend to create diagrams that can be
included in sphinx made documentation? In the past I used xfig, but was not
happy with font quality. My understanding is the diagrams would be saved in
a .png file and I should use an image directive in the relevant .rst file.

You can simplify this by taking assignment out of the picture::

I was assuming that a comma has the highest order of evaluation, that is
the expression 8, 9 should make a tuple. Why this is not the case?
