Re: Creating A Tuple From A List, Adding To Tuple As You Do

Karsten Heymann

Hi Jeff,

Jeff Nyman <je*******@gmail.comwrites:

I did try this:

for count in range(0, len(DC_List)):
DC_List.insert(count, '')

On additional note: You can be quite sure you'll never have to iterate
over the length of a list (or tuple) in python. Just iterate over the
list itself:

for DC in DC_List:
# do something with DC.

Yours

Unless you want to modify the list in place.

for i in range(len(cities)):
cities[i] = (cities[i], '')

#or perhaps better

for i,city in enumerate(cities):
cities[i] = (city,'')
