[Tutor] apihelper in dive into python
Hi guys, I've got the following problem: I tried to run the example-program apihelper.py in chapter IV of Dive into Python and got the following error message: Define the builtin 'help'. This is a wrapper around pydoc.help (with a twist). This is not the Output I expected, however I have no idea how to fix this. Anyone an idea? I am running a Win7 and Python(x,y) 2.7.5.1 Thanks for your help!

Its hard to give specific help since I don't know the file format
and most of your code is using non standard-library modules.
A couple of suggestions would be to
1) convert the code into a few functions each doing one
specific job. For example the plotting code and the
reading code could be separated out. That makes it
easier to read the overall program flow and easier
to test those individual functions if you change them.
2) You have quite a few redundant or misplaced assignments
going on, or things happening inside loops that
shouldn't be. Again removing the surplus just makes
the rest of the code easier to grasp.
I have found a way for this to work for a couple of the hours (see
below) but it requires a lot of set up to do each hour and I am sure
there must be a simpler way using loops? I also need to find a simpler
way as I would like to eventually do daily for 1st jan to 31st Dec
If you put the code into smaller functions that will simplify the design
of your bigger program. Each function should have one clear purpose and
be as standalone as possible. It should take in the
date it needs as parameters and pass back a value.

Why aren't these with the other initialization code above?

Why aren't these with the other initialization code above?
for (path, dirs, files) in os.walk(MainFolder):
for dir in dirs:
print the dirs are:, dir
path=path+'/'
this appears to be in the loop but its the same
value each time so you repeat the same assignment
over and over.
for ncfile in files:
fileext=ncvariablename+'.nc'
if ncfile.endswith(fileext):
print dealing with ncfiles:, path+ncfile
ncfile=os.path.join(path,ncfile)

ncfile.close()
Indentation seems to have gotten lost in email transit.
Maybe you didn't post in plain text?
#combine all data from the chosen variable to make one array for analyses
cdftime=utime('seconds since 1970-01-01 00:00:00')
ncfiletime=cdftime.num2date(TIME)
for i in ncfiletime[:]:
ncfiletime=i
This is a really bad idea. You are using the same variabvle name to hold
the collection you iterate over then reassigning it to the items within
the loop. Why not just use i (but use a better name!) within
the loop body rather than reassign it?
And if you must reassign it use a name other than the one you already
used for the collection. Using the same name in two different ways
is a recipe for confusion.
timestr=str(ncfiletime)
d = datetime.strptime(timestr, '%Y-%m-%d %H:%M:%S')
date_string = d.strftime('%H')#combine by same hour
print the ncfiletime is:, ncfiletime
print the date_string is:, date_string
if date_string=='00':
time00.append(TSFC00)
elif date_string=='12':
time12.append(TSFC12)
else:
pass

big_arraytime12=N.ma.concatenate(time12)

map.drawcoastlines()
map.drawstates()
map.readshapefile(shapefile1, 'REGIONS')
x,y=map(*N.meshgrid(LON,LAT))
plottitle='TSFCmax00'
another constant assignment that could be in the
initialization code section
plt.title(plottitle)
CS = map.contourf(x,y,MAX00, ticks, cmap=cmap)
l,b,w,h =0.1,0.1,0.8,0.8
cax = plt.axes([l+w+0.025, b, 0.025, h])
plt.colorbar(CS,cax=cax, drawedges=True)

[Tutor] How to create a sqlite table schema dynamically
Hello everyone,
I am stack with a problem that I can't find a solution:
I need to create a sqlite schema dynamically, I've got a dictionary with
text keys: RedHat, CentOS, SLES9,..., etc, etc
My intention was at the time of creating the table schema run a loop
through the dictionary keys and incorporate them to the schema:
for os in osDict.items():
cur.execute('''CREATE TABLE mytable(week INTEGER NOT NULL, os TEXT NOT NULL,
number INTEGER NOT NULL)''')
But I don't know how to pass the os key to the sqlite command.
Thank you in advance for any help,
Kind regards,

You are using the stat module [0]. You need to get the stat info
separately. Here's the first paragraph from the stat module docs:
The stat module defines constants and functions for interpreting
the results of os.stat(), os.fstat() and os.lstat() (if they
exist). For complete details about the stat(), fstat() and
lstat() calls, consult the documentation for your system.
This looks a bit ugly and error-prone to me, but you could do
something like this:
stat.S_IRWXU os.stat('/usr/bin/python').st_mode
Better yet? Let os.access() [1] do the bitmath for you:
os.access('/usr/bin/python', os.X_OK)
Good luck,
-Martin

You're using the stat module as described here:
http://docs.python.org/2/library/stat.html
The constant stat.S_IRWXU is listed under a section that just to
defining the constant, reads:
The following flags can also be used in the mode argument of os.chmod():
Which means, that you can do, for something like:
import os
import stat
os.chmod('/some/file/some/where', stat.S_IRWXU)
This has the effect of changing the file mode for the specified file
to read, write, execute for the user only and is the equivalent of
executing 'chmod u+rwx /some/file' or 'chmod 700 /some/file' from the
command line.

[Tutor] mixing 64 bit and 32 bit
Hi, At my office we have a mix of XP (32bit) and Window 7 (64 bit). I installed python 64 bit on the windows 7 machines and 32 bit on the XP machines. The question is can the different version run the same code without causing issues. Can the 64 bit use the same byte code as the 32 bit? It seems to be working but I thought best to check.

Look in the os.path module for a bunch of mode/access
test functions for common tests.
Or
os.access() takes a filename and flag variable (one of os.F_OK,
os.R_OK, os.W_OK, and os.X_OK) which returns a Boolean result depending
on whether the file exists, is readable, writable or executable
respectively.
Alternatively use os.stat() and treat the mode attribute
result as a bitmask using the stat flags

Its hard to give specific help since I don't know the file format
and most of your code is using non standard-library modules.
A couple of suggestions would be to
1) convert the code into a few functions each doing one
specific job. For example the plotting code and the

easier to read the overall program flow and easier
to test those individual functions if you change them.

I have found a way for this to work for a couple of the hours (see

Indentation seems to have gotten lost in email transit.
Maybe you didn't post in plain text?
#combine all data from the chosen variable to make one array for analyses
cdftime=utime('seconds since 1970-01-01 00:00:00')
ncfiletime=cdftime.num2date(TIME)
for i in ncfiletime[:]:
ncfiletime=i
This is a really bad idea. You are using the same variabvle name to hold the
collection you iterate over then reassigning it to the items within the loop.
Why not just use i (but use a better name!) within
the loop body rather than reassign it?
And if you must reassign it use a name other than the one you already used
for the collection. Using the same name in two different ways
is a recipe for confusion.
timestr=str(ncfiletime)
d = datetime.strptime(timestr, '%Y-%m-%d %H:%M:%S')
date_string = d.strftime('%H')#combine by same hour
print the ncfiletime is:, ncfiletime
print the date_string is:, date_string
if date_string=='00':
time00.append(TSFC00)
elif date_string=='12':
time12.append(TSFC12)
else:
pass
big_arraytime00=N.ma.concatenate(time00)
big_arraytime12=N.ma.concatenate(time12)
MAX00=big_arraytime00.max(axis=0)

What should I be looking for? Python 2.4.3 (RHEL 5)
v2.4? Hmm, old. I think this is still valid tho'
2.4 is old, but it's still supported by Red Hat Enterprise Linux, so it
will be around for a few more years.
