diagrams

found a nice tool to draw diagrams, called

Dia Diagram Editor
http://www.gnome.org/projects/dia/
does support UML.

nice for design diagrams, overviews and so on.

havent checked all of its functions, but its intuitive and works fine.

timestamp

to get an actual time stamp, also insertable in sql database as date type


import datetime, time

stamp=datetime.datetime.fromtimestamp(time.time()).strftime("%Y-%m-%d %H:%M:%S")


compute checksum

To identify content..


import md5
#file = open("someFile")
#contentstr = file.read()
checksum = md5.new(contentstr).hexdigest()


get absolute path of a script

if you need the absolute path of the script you are running at the moment:

absPath=`echo -n \`pwd\` ;( [ \`dirname \$0\` == '.' ] && echo ) || echo "/\`dirname \$0\`"`

for example useful to build up libary paths in project folders.

actual time

to get actual time:

from datetime import datetime
now = datetime.datetime.now()

this will give you a datetime object which is often used by other methods. For string formatting use:

now.strftime(format_string)

* %a – Wochentagsname kurz
* %A – Wochentagsname
* %b – Monatsname kurz
* %B – Monatsname
* %c – Zeit und Datum
* %d – Monatstag 1-31
* %H – Stundenzahl 0-23
* %I – Stundenzahl 1-12
* %j – Kalendertag 1-366
* %m – Monatszahl 1-12
* %M – Minutenzahl 0-59
* %p – AM oder PM
* %S – Sekundenzahl 0-61
* %U – Wochenzahl 0-53 (Sonntag 0)
* %w – Wochentag 0-6
* %W – Wochenzahl 0-53 (Montag 0)
* %x – Datumsangabe
* %X – Zeitangabe
* %y – Jahr 0-99
* %Y – Jahr
* %Z – Zeitzone
