Hi,
I'm writing an application to analyse my Apache access_log file. In
the below script (which is based on an example I found in 'How to
think as a Programmer'-) I want to measure the amount of hits per
hour. I know it is not the best algorithm but it works for now.
I see some strange things: on rather small (it must be +/- < 4000 )
entries in the access_log, my script works fine. Above this limit, I
get the following error.
Traceback (most recent call last):
File "hits_per_uur.p y", line 18, in
lijst.append(in t(datum[1]))
IndexError: list index out of range
Question: do lists have a limit? Anyone know how I can change this
simple script so that it works for more entries as well.
------------------------------------------------------------------------------
import sys,string
def inbucket(lijst, low, high):
count=0
for num in lijst:
if low<=num<high:
count=count+1
return count
f=open('c:/summary.txt','a ',1)
f.write("Hits per uur" + "\n")
lijst=['']*0
data=sys.stdin. readlines()
for line in data:
words=string.sp lit(line)
datum=string.sp lit(words[3],':') # datum bevat de volledige datum:
[16/Sep/2003:05:22:57 +0200]
lijst.append(in t(datum[1]))
numbuckets=24
buckets= [0]*numbuckets
bucketwidth=24/numbuckets
for i in range(numbucket s):
low=i* bucketwidth
high=low+bucket width
buckets[i]=inbucket(lijst ,low,high)
for num in range(len(bucke ts)):
output=str(num) + "\t" + str(buckets[num]) + "\n"
f.write(output)
f.close() 2 1260

The error could be in datum[1]. Did you double-check that datum has at
least two elements?

It probably means that there's an entry in the log that isn't what you
expect. The error is being generated by the input data; print the
contents of `datum' before you run that code, or check it out in a
debugger, to see what it contains.

No, lists do not have any such limitation. The code that's generation
the exception isn't dealing with a large list, anyway.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
