Search Results

Do not add a duplicate entry in the first place:


tut_links = {}
for subdir, dirs, files in os.walk('./html/tutorials/blah'):
for tut in files:
if tut.endswith(".html"):
...

Is each value of the dictionary:
(a) a list (or array) of URLs? or
(b) a comma-delimited string of URLs?

If you want (a), then try something like the following:


tut_links = {}
for subdir,...

They are working just as expected. For a moment, disregard the fact that your regex is a look-behind assertion.

The "search" method searches for the pattern and displays it. Since you have greedy...

Its just more string processing. You don't need extra modules to do the job. Whatever code writes output in this form var=value , make it write as {"var","val"}

Corona is correct - most command line utilities are tuned and designed for a particular purpose, and really are very close to as good as it gets. Unless you are doing this to learn coding, or have...

Code which calls system() a lot, like this one, are often exceptions to the rule. It uses C and shell instead of just shell :)

Also I am wondering, why do this in C? Shell would be just as good for this.

What I am suggesting is

1) Download tmp_file
2) Open tmp_file in program
3) Unlink tmp_file (yes, while still open)
4) Search for line
5) Print results
6) Close file (which will now disappear...

fread(tmp_file, buflen, 1, filepointer);

Except, what do you mean by "queried"? And how will dumping it wholesale into memory help you? I suspect it won't. Usually you'd operate on lines...

Since arrays are not arbitrary-sized in C, you would be wasting a lot of space.

Also, just dumping data into the array wouldn't make it line up with the array. You would still need to process the...

Speaking more generally, C does have a way to slurp an entire file into memory at once: mmap. It's actually better than reading it into memory, a 200MB file won't waste 200MB RAM just sitting...

Corona corrected your problems. Consider a more generalized approach.
This is not production code. It could use more error checking, for example. I use it for quick and dirty stuff.

It breaks a...

C does not change what variables do depending on their type, or do anything for you when you ask it to convert one type to another. At best, it will ball it up and cram it through the mail slot,...

Hi, wisecracker.

From the python os.system documentation:

On Unix, the return value is the exit status of the process encoded in the format specified for wait().

You should read the man...

The return value of os.system("shell command"); is the return code of whatever was ran. You'd check for success by checking if it was zero.

Why go outside of Python to perform the file search?


import os
import re

srchFile = 'GeoIP.dat'
srchDir = '/usr/share'

for root, dirs, files in os.walk(srchDir):
for file in files:...

sed "/pattern/s/'[^']*'/'new text'/" infile

if a line contain the pattern then the substitution apply otherwise the line is just diplayed without substitution

scanf() has an unfortunate problem where, if it finds any bad data in the stream, it puts it back. You are asking for %d, so it looks for digits. If it sees any non-digits, it will give up and not...
