python - grab data between 2 constant chars

Here is an example of the data:

x = '[ 5 | 6 | 7 [' # number 1
y = '[ 10 | 11 | 7 [' # number 2

For number one, I just want 5. Number 2, I just want 10. How can I do this?

You seem to want to isolate the 2nd space-separated field. Use str.split() for this:

for s in ('[ 5 | 6 | 7 [', '[ 10 | 11 | 7 ['):
  print s, " => ", int(s.split()[1])

If you want all of the numeric fields, use str.isdigit() to determine which fields are numeric, and filter() to create a new list:

for s in ('[ 5 | 6 | 7 [', '[ 10 | 11 | 7 ['):
  print filter(str.isdigit, s.split())

If you don't know if there are spaces around each number, you can isolate the numbers using re.findall():

for s in ('[ 5 | 6 | 7 [', '[ 10 | 11 | 7 ['):
  print re.findall('\d+', s)
