I have a dictionary. Each key contains a list. I am using the
contents of the list to build a portion of a command line.
However, before I can build the command line, I have to make sure that
the command isn't too long. This means that I have to step through
each item in the list twice: once to check the length and once to build
the command. Is there an easier/better way to do this?
for key in dict:
tlen = 0
for item in dict[key]:
tlen = tlen + len(item)
if tlen > 200:
#break command portion into multiple portions ...
for key in dict:
for item in dict[key]:
#buld command
