It was the first (and only one actually) python code that i have written, it changes my desktop background every 5 seconds, "rebuild" the file that has the wallapapers' path with every file that have in a certain directory and change the wallpaper according to my mood (there is 3 options SFW, kinda SFW and totally NSFW).

I did removed the file paths to post it here.

from subprocess import callimport timeimport sysimport globimport shutildef rebuild():    myFile = dict()    thelist = dict()    filename= dict()    for x in range(0, 3):        filename[x] = '/path/list' + str(x) +'.list'        myFile[x] = open(filename[x], 'w')        thelist[0] = glob.glob("/path/*")        thelist[1] = glob.glob("/path/*")        thelist[2] = glob.glob("/path/*")        myFile[x].write("%s\n" % "# xfce backdrop list")        for item in thelist[x]:            myFile[x].write("%s\n" % item)        myFile[x].close()    print("Done rebuilding")if ((len(sys.argv)) >=2):    if (sys.argv[1] == "--rebuild"):        rebuild()    else:        print("To rebuild the wallpaper database use the parameter : --rebuild")while (True):    with open('/path/parameter') as f:        parameter = f.readline().rstrip()        print(parameter)        if (parameter == "0"):            shutil.copyfile("/path/list0.list", "/path/backdrop.list")            call(["/usr/bin/xfdesktop", "--reload"])        elif (parameter == "1"):            shutil.copyfile("/path/list1.list", "/path/backdrop.list")            call(["/usr/bin/xfdesktop", "--reload"])        elif (parameter == "2"):            shutil.copyfile("/path/list2.list", "/path/backdrop.list")            call(["/usr/bin/xfdesktop", "--reload"])        else:            shutil.copyfile("/path/error.list", "/path/backdrop.list")            call(["/usr/bin/xfdesktop", "--reload"])            print("Calling the error list, no parameter found")    time.sleep(5)

Also, I wrote a decryption program in under 100 lines to go along with it.

the stupidly long line is just a reported image from http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

it can be done with proper formatting under 100 line using, say, the lightweight spaceship instead of the gospel glider gun, but it would look worse so yeah, take that line and deal with it

i also just found out that if you google "conways game of life" there is another google easter egg

edit: how the hell do i show line numbers?

Not really an app, but hey I use it every now and then since working with web.

In an editor which supports search replace using regex (like sublimbe text, notepad++ etc):

Search for: [\r\n]{2,}Replace with: \n

This will replace 2+ repeating "new lines" with a single newline.

This made me remember an assignment for our Natural Language course earlier this semester.

Here's an excerpt:

sed -r -n 's/[^0-9]*([0-9]+[.[0-9]+]?)[^0-9]*/\1\n/pg' $INPUT | sed -r '/^$/d' > $OUTPUT1sed -r "s/[[:alpha:]\'-]{6,}|[^[:alpha:]]/\n/g" $INPUT | sed -r '/^$/d' | sort | uniq -c > $OUTPUT5

Useful when you are working with natural language processing systems. Or, in this case, if you just want to find the numbers and big words in a text!

Its a calculator I made using loops and common sense.Its about 150 lines.

it might be nice naming the source, if this is the case?

that just computes pi though and doesn't save it within a file and tells you the decimals

sure, it's not a mere copypaste, but as it gave you some... inspiration, the source deserves a little link, just for reference

made this in python(2.7.6), it calculates all prime numbers till 999

for n in range(1, 1001):    for x in range(2, n):        if n % x == 0:            print n, 'equals', x, '*', n/x            break    else:        # loop fell through without finding a factor        print n, 'is a prime number'

edit(s):

cleared a typo.

at the moment looking to how far i can push it up with this code.

Just a simple python 3 script with some functions to create, populate and query a database of transactions.

Helps me keep track of mah monay!

The goal of this script was to create a stepping stone to move from excel (libre office calc, actually) to mysql and php and be able to log my transactions from the web without having to store the files in dropbox or having to ssh.

But that's probably going to take a looooooong time! I'm still trying to figure out some functionality to be able to categorize the transactions (that's why there is an extra 'type' column in there) to make searching and "data mining" easier.

so technically i would only use 1 line

This would be a good way to make people work for your source code or even write a script to do it for them
