Hello All,
I am working my way through learning python as a language. I am having
some issues with something that looks right and does not work. I am
trying to get myself more familure with reading files. Based on the
tutorials at www.python.org This "should" work. but im not sure what
the issue is.
===SNIP===
import string
vsftpd=open('vs ftpd.conf', 'r')
print vsftpd
vsftpd.read()
vsftpd.readline s()
vsftpd.close()
===SNIP===
When I check the permissions to ensure they are correct I get the
following.
stat vsftpd.conf
File: `vsftpd.conf'
Size: 4137 Blocks: 16 IO Block: 131072 regular
file
Device: 802h/2050d Inode: 51010 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 1000/ testing) Gid: ( 1000/
testing)
Access: 2005-12-19 10:21:04.000000 000 +0000
Modify: 2005-12-16 12:34:00.000000 000 +0000
Change: 2005-12-16 12:34:00.000000 000 +0000
When I run the script I get the following:
python reading_file.py
<open file 'vsftpd.conf', mode 'r' at 0xb7d742a8>
Does anyone have any advice on this issue at all.
Regards,
Johhny.

especially if it is a 100MB text file:
mytext = "" # re-bind the name 'mytext' to the empty string
If you have no further use for the variable, then "del mytext" will
also free up the memory, and make it clear to the reader that you're
done with the memory.
It makes clear you're done with the *name* since that's what ``del``
deletes from the namespace, not the object. I know that you know this but
many people seem to think ``del`` get's rid of the object like a call to
`free()` in C.

Hi all,
I suppose some of you know the program Redmon (type redmon in google, first
result). This neat little tool allows to hook up any functionality to a
printer by putting the file printed to the printer to standard in.
You have to provide yourself the program that does something with that data,
so I thought with some quick c/c++ programming that would be no problem. I
tried dozens of ways of reading the data from stdin or cin,...

Greetings,
I need to read (unformatted text) from stdin up to EOF into a char
buffer; of course I cannot allocate my buffer until I know how much
text is available, and I do not know how much text is available until I
have read it... which seems to imply that multiple reads of the input
stream will be inevitable.
Now I can correctly find the number of characters available by:

Hi folks,
Suppose I have a large (1 GB) text file which I want to read in
reverse. The number of characters I want to read at a time is
insignificant. I'm confused as to how best to do it. Upon browsing
through this group and other sources on the web, it seems that there
are many ways to do it.
Some suggest that simply fseek'ing to 8K bytes before the end of file,
and going backwards is the way. In this case, am I guaranteed best
results...

Hi. I'm having trouble reading some unicode files. Basically, I have to
parse certain files. Some of those files are being input in Japanese,
Chinese etc. The easiest way, I figured, to distinguish between plain
ASCII files I receive and the Unicode ones would be to check if the
first two bytes read 0xFFFE.
But nothing I do seems to be able to do that.
I tried reading it in binary mode and reading two characters in:

I've got to read info from multiple files that will be given to me. I
know the format and what the data is. The thing is each time we run
the program we may be using a differnt number of files, with different
file names each time. So i'm writing into the code to ask the user how
many files, and what their names are. From each we'll read in 2 lines,
then do some math using all of those lines. Then do it again on another
set of lines. ...

Hello, I have a basic question about reading files.
I have several data files where the filenames are identical except for
a short (3 character) prefix. I inherited this code and the person who
developed it was making a duplicate of each file and then deleting the
prefix on the copied file so the following statement could read a
generic "filename":
