Parsing files (ics/ icalendar) using Python -


I have .ics file in the following format, what is the best way to parse it? I need to retrieve the summary, details and time for each entry. 

  BEGIN: Visilendar X-Lots-charge: UTF-8 version 2.0 Prodeed: - // Lotus Development Corporation // NONSGML Notes 8.0 / N Method: Publication Start: Vitiaimafon Tijiaidi: India Started Standard DTSTAR: 19000101 T 20000 TJFFSTFM: +0530 TJFFSTO: +0530Ed: Standard Inter VTIMZEN Start: VAITNT DTStart; TGID = "India": 20100615 T111500 dtnd; TZID = "India": 20100615T121500 TRANSP: Opaque DTSTAMP: 20100713T071035Z Category: Public Description: Email \ nDarlene \ n Murphy \ NDR.

Looks good.

For example, to write a file:

Import the calendar from the calendar, import it from the import of the day, import PITES from the time of import UTC # timezone Cal = calendar () cal.add ('prodid', '- // my calendar product // mxm.dk //') cal.add ('version', '2.0') event = event (event.add () 'Summary', 'Python meeting about calendaring') event.add ('dtstart', datetime (2005,4,4,8,0,0, tzinfo = UTC)) event.add ('dtend', datetime ( 2005,4,4,10,0,0, tzinfo = UTC)) Event.add ('dtstamp', datetime (2005,4,4,0,10), 0, tzinfo = UTC)) Event ['UID' ] = '20050115T101010 / 2 7346262376@mxm.dk 'event.add (' priority ', 5) cal.add_component (event) f = open (' example.ics', 'wb') f.write (cal.to_ical ()) f.close ( )

Tadaaa, you get this file: 

  BEGIN: VCALENDAR PRODID: - // My calendar product // mxm.dk // VERSION: 2.0 starts: VEVENT DTEND; VALUE = date: 20050404T100000Z DTSTAMP; VALUE = Date: 20050404T001000Z DTSTART; VALUE = Date: 20050404T080000Z priority: 5 Summary: calendaring dragon meeting about UID: 20050115T101010/27346262376@mxm.dk end: Venture inter Visilendar

But what is this file? 

  g = open ('example.ics', 'rb') gcal = calendar.from_ical (g.read ()) for component in Gcal.walk (): print component.Name You can easily see:  
  & gt; & Gt; & Gt; VCALENDAR VEVENT & gt; & Gt; & Gt;  
 
 About parsing data about events: 
 
  g = open ('example.ics', 'rb') gcal = calendar. G.read () for component in to_ical (Gcal.walk ()): if component.name == "VEVENT": print component.get ('summary') print component.get ('dtstart') print component .get ('Dtend') Print component.gate ('dtstamp') g.close ()  
 
 Now you get: 
 
  & gt; & Gt; & Gt; 20050404T080000Z 20050404T100000Z 20050404T001000Z> About Calendaring & Gt; Python About Calendar

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
