Programming :: Waiting For File To Copy Before Continuing Processing (Python)
Mar 25, 2010
I have a Python script that copies a couple of DLL's and EXE to a directory before running the EXE. It can be a fresh copy or the files can already be in the target directory and are then overwritten. The script uses shutil.copy() to copy the files and that works but as the files are copying processing continues and the script tries to run the files mid copy, causing an error.
I need a way to wait for the files to finish copying before the script continues. Putting the thread to sleep isn't good enough, calling os.system("copy ...") also doesn't work, using os.path.exist() won't work because the file will exist during the copy.

I've already used line split stuff to transform my data into something like this in a text file:
Code:
['1', '1', '3', '20.7505207']
['2', '1', '3', '23.0488319']
['3', '1', '3', '-1.5768747']
['4', '1', '3', '-26.4772491']
[code]....
How can I get this on a python program so I can manipulate it as an array?

I use the below loop to process each file (listed in a text file) with a software. During processing the software asks me to enter a value and continues processing of that file after I enter the value. I have those values stored in a text file "myfile". What I want is to get the values directly from myfile when the software asks "please enter the title:". I dont want to enter them all manually. But i could not figure out how to code this in Bash script.
Code:
for ((i=1,i<=$NR,i++)); do
--command of the software comes here--
done

I have managed to create a HTML file inside python code,convert this to a PNG file through a Python script ?
EDIT: Details added: I have a python script which generates map-legends in the form of an html file. The legend generated have to be pasted on a map which is in a png format. A png format file can be pasted on another png format file easily. But because the legends generated are in a html format I cannot paste it on the map file !!
EDIT: Details added: I did Googling first but it resulted in various soft wares for above purpose which I don't want !!

I've run into a little problem, for which I seem to be unable to find an answer. The concept is the following: one machine runs a python script which advertises itself as 'OBEX File Transfer' and receives incoming data, using the Lightblue python module. The script itself is slightly different, but here's an example which effectively works in the same way:
[Code]....
print "Saved received file to MyFile.txt!" This works fine, though I would like to retain the original filename that is being sent to the machine, instead of overwriting a fixed file. Generating a new name wouldn't be such a problem, if I could get the MIME type or filename which is (presumably) being sent in the header of the request. Does anyone know of a way in python to receive incoming files and retain their filenames via Bluetooth?

I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.

I'm woring on a personal research project and would like to know if there are lilypond parsers for python available or I'll have to create my own. Just in case you are wondering: I don't need to typeset the content of the lilypond file, just understand what's written in the file (what notes, what duration, when in time to play each one, etc).

I have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.

I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

I don't think this is a "perl one-liner" of find and replace. I'm trying to auto-fill some information in a listing of files. The simplest example is that in the files the following exists:
I would want the script to find this and populate it with something like -- Date : 20101004-1758
I have a few more similar fields to autofill, and I'd like to do this from within a larger perl script I'm developing to process these files. So, how I perform in-place file modification from within a perl script?

I've been trying to sort this out for several hours and I?m totally lost? I?ve been searching around, but haven?t found the solution to my problem. I have a directory with 100 files. I need to copy 10 lines of each files (let?s say from line 45 to 55) into one unique file. So I guess I could use sed ?w, but I didn?t manage to write the right script. I also tried using a loop to create 100 different files, each one with the 10 lines) to concatenate them later on. But I only got 1 file, not 100.
