Programming :: Python - Get Text File Data Into An Array On Python?

Nov 30, 2009

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?

Programming :: Parse A File Containing Billions Of Records?

Nov 17, 2010

I have to parse a file containing billions of records and populate them in the Data structure. I have used a lot of C++ class and creating objects of the class I am storing the information retrieved by parsing the file.

Now as the file become huge and number of objects become very large my code is getting bad_alloc error as it is not finding any space avalable in the heap for allocating new object.

Is there any way to parse the file?

Programming :: Parse And Modify File Without Creating A Copy?

Nov 4, 2010

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?

Programming :: Perl Read File And Parse Blocks?

Aug 21, 2010

I am trying to make a perl script which reads data from a file and parse it. The data in the file has the following syntax

Code:
Device Physical Name : Not Visible
Device Symmetrix Name : 1234
Device Serial ID : N/A
Attached BCV Device : N/A
Device Capacity

[Code]...

Each unique record starts with "Device Physical Name". So, I have a set of records within "Device Physical Name". I want to read this set of records starting from "Device Physical Name" and ends up till next "Device Physical Name". Offcourse FS is ":", and I just want to print/or later put info in a csv file.

Programming :: When Parse A XML File - Should Rely On The Order Of Elements?

Programming :: Parse Multiple Variable From Text File With Bash?

Jul 13, 2010

I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:

:::::::::::
var1=value1
var2=value2

[code].....

I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.

Programming :: Converting A HTML File To A PNG File Through Python Script?

Jan 29, 2010

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 !!

Programming :: Python Bluetooth File Exchange

Feb 13, 2011

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?

Debian Programming :: Searching For A List Of Strings In File With Python

Oct 14, 2013

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.

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.

Programming :: Saving File Data Using Python In An Embedded System In An Safe And Fast Way?

Apr 19, 2011

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()?
