Hi all,
I've created a script that reads in a file, replaces some data (regex),
then writes the new data back to the file.
At first I was convinced that "w+" was the tool for the job. But now
I'm finding that the contents of the file are deleted (so I can't read
the data in).
f = open('_i_defin
To make it write over the data, I ended up adding, which seems to work
fine.
f = open('_i_defines.php', 'w+')
data = f.read()
f.seek(0)
f.truncate(0)
...process data, write file, close...
Now that I look at it, I could probably take out the f.seek().
Thanks for your help!

I have a collection of ordered numerical data in a list. The numbers

Hi,
I need to match 3 small strings in a small text file (about 200 words
of text).
Would it be faster to write 1 compiled regex that matches all 3

the same job?
Thanks!
