Hello, I searched the web and python.org but I haven't found a good resource
that explains how to upgrade python from 2.4 to 2.5
What I'm wondering is whether I'll have to start from scratch on the
installation of all my external modules such as Numpy, Matplotlib, PyXML,
etc...
Could someone pl
I know there must be a better way to do this with slices, but I can't seem to
figure it out - I keep getting errors about the need to have the same
dimensions:
Here's what I'm trying:
>>> type(time)
>>> type(new_data)
>>> shape(time)
(1334,)
>>> shape(new_data)
(1334, 54)
>>> newArray=concatena
Thank you again.
I can see your point about not wanting the tempDATA var hanging around, so I
guess this is better as a function. And yes, the transpose is for the 'next
step' - sorry if that cause anyone confusion.

Thanks,
I'm not really trying to create a function. I actually thought this would be
as simple as the 'load' command to get the data in from a file. But I just
couldn't find the documentation online to do it once i have the data already
'inside' of python as a list. So, my options are:
1) write
Hello, I have a list of strings:

...

Could someone please explain 'slices' also for dictionaries?
basically, I'd like to know how you would call every 3rd element in a list
of lists...
My logic says: ThirdElems=List[:][2]
Which to me reads, for every item in List (which are lists), return the
third item.

Answering my own question here, but for the sake of it... adding:
os.chdir(newpath)
makes it all work... so we have:

p = sub.Popen(['/bin/bash', '-c', cmd],
stdout=sub.PIPE, stderr=sub.STDOUT)

int(dates_list[i][0][6:8]),int(dates_list[i][0][8:10]),
It's not pretty, but this is what seems to work... I'd be happy hear more
about a better approach... I like the idea of using a list, but ran into
troubles with min and max, maybe I don't entirely understand the lambda
function, but when I tried a list, I got an error that min() has no optional

Thanks everyone these seem like promising directions to go... Eric, any
chance you could share your 'similar' code? The problem it seems with
paramiko is that it has little 'newbie' documentation, and I'm not clear how
to set up the reverse port forwarding on it. Thus I may need to use the

WAY too large a project I'm afraid. Yes, that would be the one which
would make me an 'expert' in Python ;)
Too bad there's just no time right now...

And just what would that be? Ask yourself that.. then perhaps folks on

I have a FORTRAN program which reads in unformatted sparse matrix
data. Rather than rewriting the code in Python, I was hoping there is
a way to call the Fortran program, passing filename variables TO
Fortran, and returning the data (which is an array) back to my .py
code for use there.
Is there a

It aint pretty! And if I had just walked away, it probably would've
taken half the time in the morning, but here's what I've come up with
(any suggestions for improvements, or course are welcome):
for d in data:
w = len(d)
if d[0] <= tinit+60:
d = column_stack(d)
Ug,
It still doesn't make sense due to the sum/cnt where cnt is just an
int, and sum is a 1-dimensional array!
I'm missing something here about working with numpy arrays...

Thanks for the feedback,
The average was a little bit goofed up. Here's what I have now:
for d in data:
if d[0] <= tinit+60:
d = column_stack(d)
cnt=cnt+1
sum = sum+d
else:
avg = sum/cnt
if init==0:
newData = av
Oops, I meant it crashes at line 7..

Hello, I'm trying to calculate an average for columns in my
array(data), there's a catch though, I want to create a new array of
shorter length (NOTE: this crashes at line 8):
1) tinit = data[0][0]
2)for d in data:
3)if d[0] <= tinit+60:
4)sum = sum+d

Jessica,
Assuming you have python installed on your system (Windows?, *nix?),
then all you have to do is double click the .py file and it will run.
If you want, you can run it from the command line:
C:\> python yourfile.py

I also noted, if I used:
tmp = data[6].strip().split()
rather than:
tmp = data[6].strip().split(' ')
I eliminated the 'empty' elements...

I can't recall how to do this:
I want:
a = [int(x) for x in tmp]
but, my tmp has some empty elements, so it fails...
Therefore I want to be able to say:
a = [int(x) for x in tmp IF x in tmp]
I know there's a way! Ive seen it before, but now cannot find it! 'if'
is a pretty generic thing to se
Hello all,
I'm trying to write a program which will take a path, look in it for
all files matching a certain pattern, then create javascript player to
play them. A key part of the code at this point is:
searchPath = imageRoot + '*' + imgExt
avail = glob.glob(searchPath) #will glob work over http
Hello all,
I'm writing a program which take input about a path. The path may be
http or absolute or local. Once I have the path, I want to search the
directory for images (type also defined by user), then get a count on
the number of images in order to build the rest of my program:
searchPath = i
Excellent. Thanks Luke, that seems to be working

Thanks so much! Now another task, associated with this one... what I
actually ultimately want is to just pull out several fields from the text
file in the zip archive (there is actually only one file).. so, my goal is
the to create a file that looks like:
t[0], x[0], y[0]
t[1], x[1], y[1]
t[2], x
Thank you both! That seems to make my code much more clear... I thought
it was foolish writing files, but I just couldn't determine how to
parse the data!
Kent, one thing, regarding:
x = []
t = []
for l in data[stind:-1]:
l = l.split() # Split on whitespace
34 matches
