for loop runs only once (python)

Question

I'm having a hard time with this logic here. I need help within function process_dns_dump().

It seems like I can only run my code once, it doesn't iterate through every line.

I have a .txt document which I want to read and than generate several dictionaries correlating 'SGSN' and 'GGSN' within the same 'VIEW'.

The code is as follows:

            #!/usr/bin/env python

            def find_between( s, first, last ):
                try:
                    start = s.index( first ) + len( first )
                    end = s.index( last, start )
                    return s[start:end]
                except ValueError:
                    return "ERROR"
            def find_after( s, first):
                try:
                    start = s.index( first ) + len( first )
                    return s[start:]
                except ValueError:
                    return "ERROR"

            def process_dns_dump():

Can anyone give me a light into it? I'm losing hope.

Thanks!

Try changing if lines[0:3] == 'acl': to if lines[0:2] == 'acl':. The reason that I mention this that python will skip the meat of code if you are trying to compare a string of length 4 to a string of length 3. — USFBS

You're iterating over your file twice. Once here:

for lines in f:

And once here, inside that loop.

for linhas in f:

But normally you can only iterate over a file exactly once, and then the "file pointer" points to the end of the file, and you can't extract any more data.

One possible solution is to read the file all at once into a list of strings, and iterate over that instead. Lists don't have the "can only iterate once" restriction.

f = open(files)
line_collection = f.readlines()
for lines in line_collection:
    #...
    for linhas in line_collection:
        #etc

Another solution is to use file.seek(0) to reset the file pointer back to the beginning of the file. But that seems a little more complicated to execute in your case, since you probably want to seek to the end of the line currently held by lines after each execution of the for linhas in line_collection loop, rather than seeking to the very first character of the file.

You could also do a f.seek(0) between the two iterations, this will reset the read offset to the first byte of the file.

I'll give it a try and post results here. Thank you!

Hi Kevin, already accepted it. Thank you again. I misread it and thought it was André who gave me the answer, sorry for that.

As Kevin suggested I did it using a list of strings to iterate it as many times I needed.

#!/usr/bin/env python

def find_between( s, first, last ):
    try:
        start = s.index( first ) + len( first )
        end = s.index( last, start )
        return s[start:end]
    except ValueError:
        return "ERROR"
def find_after( s, first):
    try:
        start = s.index( first ) + len( first )
        return s[start:]
    except ValueError:
        return "ERROR"
