How about something like this
mylist = ['serverA', 'serverB', 'serverC', 'serverD','serverE', 'serverF',
'serverG']
tempstr = ""
count = 0
for item in mylist:
count += 1
if count == 3:
tempstr += (i + "\n")
count = 0
else:
tempstr += (i + " ")
print tempstr
The above code prepares an empty string variable, and a count variable. On
each iteration, it checks to see if the count is equal to 3. If it is, then
it appends the current list element to the string and also adds a newline
character("\n"), then the count is reset to 0. If the count isn't 3, it
simply appends the current list element along with a space.
Hope this helps,
Bodsda
