I'm on a mac OS X (10.3.8), and I seem to have accidentally destroyed
the default python installation. How should I put it on? Do I need to
use the unix version? any help would be greatly appreciated.

If your script is foo.sh and takes args:

subprocess.call(["foo.sh","args"],shell=True)
Should work fine. check out

As described in the docs I pointed to before:
subprocess.call("foo.sh",shell=True)
Is the way to do it without args. I think it is simplest to learn the
subprocess module because (quoting from the docs) this module intends
to replace several other, older modules and functions, such as:
os.system

Actually, after a little looking, the simple stats.py module at

scipy or R, but installation simply involves downloading the module and
importing into the cod
How about
my_string = "We the people of the United States, in order to form a
more perfect union, establish justice, insure domestic
tranquility,.."
print (x for x in my_string.split(",") if "justice" in x).next()
This isn't a regular expression, but it gives what you're looking for.

I strongly recommend trying to come up with your own projects. Just
pick small things that reflect something you actually want to do: maybe
make a simple board game, or a few scripts to help you keep all your
files organized, etc. Generally speaking I think it's easier to teach
yourself a languag
Perhaps __init__.py has what you're looking for?

You can always give any object as many names as you want:
>>> import sys
>>> s1 = sys
>>> s2 = sys
>>> s1.path
How hard would it be to have numpy/ scipy part of the python standard
library?

The difference becomes clear when you import your program into another
program (or the command line python editor). __name__!='__main__' when
you import, so the functions will not be called if they're inside the
block. This is why you see this block so often at the end of scripts;
so that the scr
I have this code:
type1 = [0]
type2 = [0]
type3 = [0]
map = {0:type1, 1:type1, 2:type3, 3:type1, 4:type2} # the real map is
longer than this
def increment(value):
map[value][0] += 1
increment(1)
increment(1)
increment(0)
increment(4)
#increment will actually be called many times through

Yes, I highly recommend the subprocess module. subprocess.call() can
do almost anything you want to do, and the options are all pretty
intuitive Whenever I need to write quick scripts for myself, it's what

There is also this way:
for index in range(len(someList)):
someList[index] = 1
This is not as pretty or concise as enumerate(), but if you've never
seen that function before this may be more clear. I assume you're
familiar with the way range and len work.

Here's an OO way that may do what you want:
>>> class MyD(dict):
... def __init__(self,dic,rep):
... dict.__init__(self,dic)
... self.rep = rep
... def __repr__(self):
... return self.rep
...
>>> apps = MyD({'alpha':1,'beta':2},'apps')
>>> apps
apps
>>> a
My usual way of emulating do-while is:
started = False
while (someBoolean or not started):
started = True
#whatever else
This simply assures "whatever else" happens at least once. Is this
Pythonic?
