Hi,
I have a file of records of 4 fields each.
Each field is separated by a semicolon. That is
Filed1;Ffield2;Field3;Field4
But there may be also empty records such as
;;;;
(only semicolons).
For sorting I used
#################
lines = file('Config.txt').readlines()# a file I want to sort
lines.sort()
ff=open('ConfigSorted.txt','w')# sorted file
ff.writelines(lines)
ff.close()
###############
It was sorted but empty records were first. I need them to be last(at
the end of the file). How can I do that?
Thanks for help
Lad
Lad,
The sort call can have a function name as an arg. You
could do:
def mycompare(s1,s2):
#return -1 to put s1's at front; 1 to put s1's at back; 0 for a tie
#if s1==";;;;" and s2<>";;;;": return 1
lines.sort(mycompare)
