Walk thru each subdirectory from a top directory

[silverburgh . meryl]

i am trying to use python to walk thru each subdirectory from a top
directory.  Here is my script:

savedPagesDirectory = /home/meryl/saved_pages/data

dir=open(savedPagesDirectory, 'r')

for file in dir:
if (isdir(file)):
# get the full path of the file
fileName = savedPagesDirectory + file + 'index.html'
print fileName

$ ./scripts/regressionTest.py
Traceback (most recent call last):
  File ./scripts/regressionTest.py, line 12, in ?
dir=open(savedPagesDirectory, 'r')
IOError: [Errno 21] Is a directory

But I get the above error:

Can you please tell me what did I do wrong?

Thank you.

 In B.py:

 import A

 A.test()

But Do I need to put A.py and B.py in the same directory?
if not, where does python look for A.py ?
And do I need to compile A.py before I can import it to B.py?

Question about strftime

[silverburgh . meryl]

Hi,

I have question about strftime.  I am trying to print the current time
in this format:

date = strftime(%Y%m%d_%H%M%S, gmtime())
print date

I run the script at 2:18 pm, but I get this: 20070210_201837

Can you please tell me why I get '20'? instead of '14' (which is 2:00
pm)?

Thank you.

 for str in strings:

 print colors[colorIndex  % colors.length]
 colorIndex += 1

Can you please tell me what is the meaning this error in general?

 UnboundLocalError: local variable 'colorIndex' referenced before
assignment

In my python script,
I have a variable define and init to 0, like this
colorIndex  = 0

and in one of my functions,  I increment it by 1
def myFunc 
   colorIndex += 1
