Re-loading updated modules

[fileexit]

Hi,
Shouldn't python recompile a module if there is a later version of the
code (.py file)? While i am debuging, i always have to exit python and
delete the pyc before every run, then start it again and import the
modules.  It seems that this is the only way for it to recompile the
new code.

What is going on? is this normal behaviour? I noticed that on both
Windows and linux (Fedora Core 4, and 5 and RHEL 4)

How to run shell commands within python

[fileexit]

How can I execute shell commands from within python.  Specifically, I
am looking for something like the shell "cat".  But this also made me
wonder how to execute shell commands anyway, just if i needed to do
that in the future.

Regular expression gone mad

[fileexit]

Hi,
Would someone please tell me what is going on here??!! Why does the
following code work

>>> a=r"Mem"
>>> pat = re.compile(a)
>>> m=pat.search(ProcMem, re.DOTALL)
>>> m
<_sre.SRE_Match object at 0xb7f7eaa0>
>>> m.group(0)
'Mem'


But this one does not!!! (Search finds nothing)

>>> a=r"MemT"
>>> pat = re.compile(a)
>>> m=pat.search(ProcMem, re.DOTALL)
>>> m


ProcMem contains:

Re: spliting on ":"

[fileexit]

> yyy
> yyy
> yyy
> xxx.xxx.xxx.xxx
> xxx.xxx.xxx.xxx

of course you will get this result...

inside the loop, when line="xxx.xxx.xxx.xxx:yyy"
line.split(":") will give a list ["xxx.xxx.xxx.xxx", "yyy"], and
element -1 will be "yyy"

but when line="xxx.xxx.xxx.xxx"
line.split(":") will give a list ["xxx.xxx.xxx.xxx"], and element -1
will be "xxx.xxx.xxx.xxx"

So the result is very very normal
