Or using the new string formatting syntax:
msg = '{},{},{}:{}'.format(*item)
The *item in the format() unpacks the tuple.

How to you convert list of tuples to string
Dear friends , I am using fedora 18 and on Python 2.7 version I have a list of tuples as shown below >> list [(1, 1, 373891072L, 8192), (1, 3, 390348800L, 8192), (1, 4, 372719616L, 8192), (2, 3, 382140416L, 8192), (2, 5, 398721024L, 8192), (3, 1, 374030336L, 8192), (3, 3, 374079488L, 8192), (3, 5, 340058112L, 8192)] (a) I need to select any element randomly the list say (x, y, xL, 8192) >>> list [(1, 1, 373891072L, 8192), (1, 3, 390348800L, 8192), (1, 4, 372719616L, 8192), (2, 3, 382140416L, 8192), (2, 5, 398721024L, 8192), (3, 1, 374030336L, 8192), (3, 3, 374079488L, 8192), (3, 5, 340058112L, 8192)] >>> import random >>> i = random.randrange(len(list)) >>> sel_item = list[i] >>> sel_item (3, 5, 340058112L, 8192) (b) Then convert the selected item in the below format i.e 1,1,373891072:8192 ( strip L and add :) >>> sel_item (3, 5, 340058112L, 8192) >> c1 = ','.join(map(str,sel_item)) # what happened to 'L' it got stripped automatically ? will these be a problem >>> c1 '3,5,340058112,8192' #last four are always 8912 and >>> c1 = c1[0:-5] + ':8912' >>> c1 '3,5,340058112:8912' >>> Any better suggestion to improve this piece of code and make it look more / pythonic Regards, Ganesh Pal -- https://mail.python.org/mailman/listinfo/python-list
