Hello :-)
Can someone please explain to me ho can I find out how many elements are
there in one record of a list?
The problem is as follows:
I have a txt file from which I read data into Python.
The file looks something like this:
01 bla bla bla 23,15 2345,67
02 alb alb 2,4 890,1
03 bal bla
in case it helps here is a very basic example:
import MySQLdb, glob, os, re, shutil
from ftplib import FTP
a=file_to_fetch
ftp=FTP('ftp_server')
ftp.login('user_name','password')
try:
aa=ftp.nlst(a)
b='/home/a'
bb=os.path.basename(aa[0])
e=os.path.basename(b)
c=open(b, 'wb')
Hi Gloom,
You should give a look at the method split (of the string objects) and
int.
The first is used do break a string into smaller pieces and the other to
convert a string to an int object, raising an exception when it is not
possible.

The len() function gives the length of a list.

Hmm. So much to say about so little code!
- the re.sub() is not needed - the split() will remove the trailing newline:
In [53]: 'a b\n'.split()
Out[53]: ['a', 'b']

Because the underlying datastore (BigTable) doesn't support them? I'm
not sure but I think this is a key to the scalability of the data store.

i can't think of anything but a loop here UNLESS you take the list from its
source one element at a time, process it then print the result.
example of this would be :
list comes in from standard input.
list comes from a database
list is read from a file.
so again

pyLint sees that you are assigning a numeroc literal and
