Debian Programming :: Searching For A List Of Strings In File With Python
Oct 14, 2013I'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 :: Python - Get Text File Data Into An Array On Python?
Nov 30, 2009I'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 :: List Sorting In Python?

Debian Programming :: Return How Many Items Occurs In List (Python)
Jan 29, 2014I going through the Python course on Codeacademy. I have some trouble understanding what I'm doing wrong. This is my code below:
Code: Select alldef count(sequence, item):
total = 0
for x in sequence:
return x
if x in sequence:
total += 1
return total
print count([1,2,1,1], 1 )
The code gives me an error: "Oops, try again. Your function fails on count([1],7). It returns 1 when it should return 0."
It should be outputting 3 because 1 occurs 3 times in the list.
Programming :: Python Error - List Index Out Of Range (Web Scrapper)

Code:

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 !!

Programming :: Python Bluetooth File Exchange
Feb 13, 2011I'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?

View 1 Replies View RelatedProgramming :: Waiting For File To Copy Before Continuing Processing (Python)
Mar 25, 2010I 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, 2011I 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()?
General :: Passing A List Of Variables To A For Loop
Mar 17, 2011I'm trying to do substitutions to a file based on passed variables.
For example, I have a file called test.txt that has 5 lines:
What I want to do is to go through that file, line by line and check for the presence of a passed variable in that line. If I have a match, then substitute and print, otherwise print line as is. My problem arises in that the number of variables is well, variable.
The code I started with was the following:
Code:
What I was hoping for was test.out to look like this:
What I get is a much longer file like this:
This makes sense after thinking about it but is there anyway to get an output like the first case?
Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?
Aug 21, 2009I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
Programming :: Create Cvs From List Text File
Dec 21, 2010I have a file with 5000 lines. it is a list of books authors, series and titles. all lines start with the author names, than there is a dash (-) than the series name, a dash again and the title of the book.
The problem I encounter is that sometime there is a series, sometime not, and as I try to enter this list in a database, I wanted to create a cvs file to import into mysql.
ex:
The best would be to be able to add in the second line, a "space dash space" just after the author name, but how to make sure it does not do it to the first line as well.
If I could separate all line with 2 dash, (grep ?) then I would be able to do a simple replace, and change the single dash into two.
Programming :: Get A List Of File Install Locations With Make It?
Dec 21, 2010I have a bit of a problem and the only solution I can think of at the moment is a very tedious one, so I was hoping there would be a better way. What I am trying to do is cross compile the PPPD program so that I can install it on an embedded system (this system does not have make/gcc on it). It was easy to cross compile it, but I can not run "make install" since I'm compiling on a secondary machine. I don't want to install PPPD on this secondary machine (I couldn't anyway, because it was compiled for a different architecture) and I can't run make install on the target machine because there is no make/build system for it.
So it seems like what I would have to do is to manually copy over each compiled file from the build machine to the appropriate location of the target machine. And the only way (that I know of) to figure out how to do this is to manually examine the Makefiles (yes, there are several for PPPD) and figure out which file should go where on the target system. This isn't trivial because it uses a hierarchy of makefiles and the probability of human error for this method is high.
Is it possible that I could run another command that would give me a list of all the commands that make install would perform? Or a list of all files and their target location for "make install"? Or possibly some other solution that I am completely unaware of that would make this task not so painful and error prone?
