Hi,

I wrote a very simple python program to generate a sorted list of
lines from a squid access log file.

Here is a simplified version:

##################################
1  logfile = open ("squid_access.log", "r")
2  topsquid = [["0", "0", "0", "0", "0", "0", "0"]]
3
4  def add_sorted (list):
5     for i in range(50):
6          if int(list[4]) > int(topsquid[i][4]):
7              topsquid.insert(i,list)
8              break
8      # Max len = 50
10     if len(topsquid) > 50:
11         topsquid = topsquid[0:50]
12
13 while True:
14     logline = logfile.readline()
15     linefields = logline.split()
16
17     if logline != "":
18         add_sorted (linefields)
19     else:
20         break
21
22 for i in range (len(topsquid)):
23     print topsquid[i][4]
####################################

When I execute the program _without_ the lines 10 and 11:

10     if len(topsquid) > 50:
11         topsquid = topsquid[0:50]

it runs perfectly.

But if I execute the program _with_ those lines, this exception is thrown:

[EMAIL PROTECTED]:~$ python topsquid.py
Traceback (most recent call last):
  File "topsquid.py", line 20, in <module>
    add_sorted (linefields)
  File "topsquid.py", line 6, in add_sorted
    if int(list[4]) > int(topsquid[i][4]):
UnboundLocalError: local variable 'topsquid' referenced before assignment


Note that now the error shown is not related with the lines 10 and 11,
but wiht a line prior to them.

Any hints?
