Thanks! That's a nice little stumbling block for a new

Please have a look at this little script:
#!/usr/bin/python
import sys
import codecs
fileHandle = codecs.open(sys.argv[1], 'r', 'utf-8')
fileString = fileHandle.read()
print fileString
if I call it from a Bash shell like this
$ ./test.py testfile.utf8.txt
it works just fine, but when I try to p

Yes, I know! I _want_ the "3rd last list element", i.e. list[-3]. But it
may be that the list does not have 3 elements. In this case, list[-3]
will throw an error, cf.:
I want to check whether, for example, the element myList[-3] exists. So
far I did it like this:
index = -3
if len(myList) >= abs(index):
print myList[index]
Another idea I had was to (ab-?)use the try...except structure:
index = -3
try:
print myList[index]
except:
print
Both methods work well, thank you!

In the re documentation, it says that the matching functions return "non-
overlapping" matches only, but I also need overlapping ones. Does anyone
know how this can be done?

Thanks Martin, you're right, it were the repr() calls that messed up the
output. Iterating the array
Hello,
I have this little grep-like program:
++snip++
#!/usr/bin/python
import sys
import re
pattern = sys.argv[1]
inputfile = file(sys.argv[2], 'r')
for line in inputfile:
matches = re.findall(pattern, line)
if matches:
print matches
++snip++

Thank you all for your helpful solutions!
