How to reload local namespace definitions in the python interpreter?

[test1dellboy3]

Hi,

I am a beginner using the python interpreter. To reduce typing effort,
I created a module called "aliases.py" containing some aliases for
objects I commonly use like -

aliases.py :
import filecmp, os, commands

op = os.path
go = commands.getoutput
dc = filecmp.dircmp
p1 = '/mnt/usbkey/flash/'
p2 = '/mnt/fat32/myfiles/flash/'

When I start up the interpreter, I can simply type -

from aliases import *

This works fine, but each time I change any of the definitions in
aliases.py, I
have to restart the interpreter and type "from aliases import *"
again. Is there any way to reload these definitions without restarting
the interpreter?

reload(aliases)

See: http://www.python.org/doc/2.4.1/lib/built-in-funcs.html

By the way, are you aware of the import ... as ... idiom?
e.g. import os.path as op

Unfortunately a simple reload of the module won't result in the required
changes to the local namespace:

$ cat test87.py
val = 33

from test87 import *
print val 33 val = 42
reload(test87) <module 'test87' from 'test87.pyc'> print val 42

See: http://www.python.org/doc/2.4.1/lib/built-in-funcs.html

By the way, are you aware of the import ... as ... idiom?
e.g. import os.path as op

This would, of course, require the user to qualify the names by
prefixing them with "op.".

What the OP listed above requires that too.

I believe the OP was suggesting

from aliases import *

which specifically loads the names in the module (or those specified in
module.__all__) into the importing namespace for use without qualification.
