My first python script.

1. Recently I started to study python . In this site I present many scripts. For simple tasks, I use bash and for more complex ones perl. Since my daughter starts to study python , so do I.


2. This script extracts the current time from a web site, translates it to IL local time and prints the results.


3. First I needed to check if the library request is installed on my debian machine. So I fired the interactive python and gave the import command:
   
   >>> import requests
   Traceback (most recent call last):
   File "", line 1, in
   ImportError: No module named requests
   
   To install the library, I used:
   
   apt-cache search python-requests
   python-requests - elegant and simple HTTP library for Python, built for human beings
   
   apt-get install python-requests
   
   


4. The script is simple and is built of the following:
   
   1. library import,
   2. read web page into memory,
   3. extract time using regular expression,
   4. print results
   
   The code is listed below:
   
   #!/usr/bin/python
   
   #process web pages
   import requests
   #handle regular expression
   import re
   
   #Get the time from the web
   #Look for the following string:... 07:14:02 UTC ...
   response = requests.get('http://tycho.usno.navy.mil/cgi-bin/timer.pl')
   m = re.search('[0-9][0-9]*:[0-9][0-9]*:[0-9][0-9]* UTC', response.content[:500])
   print "found", m.group(0)
   
   str = m.group(0).replace(" UTC", "")
   
   Lname=[]
   Lname.append("hour")
   Lname.append("min ")
   Lname.append("sec ")
   
   
   array=str.split(':')
   ix=0
   for ti in array:
     if(ix == 0):
       #adjust to IL time
       ti_i = int(ti) + 3
       print Lname[ix], ti_i
     else:
       print Lname[ix], ti
     ix += 1
