x = str.find(temp, '120.50')

I am looking for '120.50' '120.51' '122.78' etc. How can I do this with
just one str.find... I can use re if I must, but I'd like to avoid it if
possible.

In addition to Fecundo's questions, here's another. What does "temp"
contain? A single temperature string, or a temperature embedded in
a bunch of other stuff, or a whole series of temperatures, or what?

Here's what I'm doing

def exclude():
import os
os.chdir('/home/rbt/scripts')
inputFile = file('ath_ips.txt', 'r')
data = inputFile.read()
inputFile.close()
comment = '#'
net0 = '128.173.120.'
net1 = '128.173.122.'
host0 = ['50','51','52','53','54','55']
host1 = ['17','25','49','50','55','58','70']
for h0 in host0:
h0 = net0+h0
rep0 = comment+h0
sea0 = str.find(data, h0)
if sea0 >=0:
data = data.replace(h0, rep0)
for h1 in host1:
h1 = net1+h1
rep1 = comment+h1
sea1 = str.find(data, h1)
if sea1 >=0:
data = data.replace(h1, rep1)
outputFile = file('ath_ips.txt', 'w')
outputFile.write(data)
outputFile.close()

Well, since that shows nothing whatever about the content of the
"data" string (i.e. what is in that ath_ips.txt file), it doesn't
really help to answer the questions I had.

There's no need to do an explicit find() before replace(). Your 'for'
loops can be written as

for h0 in host0:
data = data.replace(net0+h0, comment+net0+h0)
for h1 in host1:
data = data.replace(net1+h1, comment+net1+h1)


Or reduce it to one 'for' loop with list_comprehensions

for host in [net0+h0 for h0 in host0] + [net1+h1 for h1 in host1]:
data = data.replace(host, comment+host)

Thanks Dave. That's very helpful.

Hi,

looking at your code is obvious that what you want to do
is to look for servers on the "ath_ips.txt" file and then
comment the line where they appear. I think this search
and replace function can be done with regular expressions
(see the re module). The servers belong to the same
network, and only the two left digits are different.

Regards,
Josef

Ah, trust me to take an industrial-control point of view and not a network
software point of view. You meant "temp" to be a temporary variable, not
a temperature, and the 120.50, 120.51 stuff are partial IP addresses, not
temperatures... how curious of me to confuse them.
