== Time and date ==
{{{#!highlight python
import time
# get seconds since epoch until now in UTC to a string year-month-dayThour:minute:second
strutc = time.strftime('%Y-%m-%dT%H:%M:%S', time.gmtime() ) 
# get seconds since epoch until now  in localtime to a string  year-month-dayThour:minute:second
strlocal = time.strftime('%Y-%m-%dT%H:%M:%S', time.localtime() ) 
}}}

== Write and reading data for a plist file ==
A plist file stores data in XML format.

{{{#!highlight python
import plistlib
value = [{'key1':123,'key2':'asdf'},{'keyx1':'testing','keyz1':'yup'}]
# save value in plist file
plistlib.writePlist(value,'/tmp/plist1.plist')
o=plistlib.readPlist('/tmp/plist1.plist')
print o
}}}

Content of the file '''/tmp/plist1.plist'''
{{{#!highlight xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
        <dict>
                <key>key1</key>
                <integer>123</integer>
                <key>key2</key>
                <string>asdf</string>
        </dict>
        <dict>
                <key>keyx1</key>
                <string>testing</string>
                <key>keyz1</key>
                <string>yup</string>
        </dict>
</array>
</plist>
}}}

== Threading ==

{{{#!highlight python
#!/usr/bin/python
# timestable.py
# calculates the times table in concurrency
import threading
import time

class TimesTable (threading.Thread):
    def __init__(self, timesTable):
        threading.Thread.__init__(self) #required
        self.timeTable = timesTable
        self.count = 1
    def run(self):
        loop=True
        while loop:
            time.sleep(1) #sleep for 1 second
            result=self.timeTable * self.count
            print "%d*%d=%d"%(self.timeTable,self.count,result)
            if self.count<10:
	        self.count = self.count+1
	    else:
	        self.count=1

# create threads
timesTable2 = TimesTable(2)
timesTable5 = TimesTable(7)

# start the threads
timesTable2.start()
timesTable5.start()
