For loops printing lists

Question

So if I make a list of people say.. greatppl = ['name1', 'name2', 'name3'] then I append to it and insert by doing

greatppl.insert (0, 'name0')
greatppl.append ('name4')

when i print greatppl it shows the list but when i create a for loop for greatppl like so:

for greatppl in greatppl: print (greatppl)

it just prints all the names then when i print greatppl again it outputs the last character in the last name

print (greatppl)
so in this case 4 would be the output

why is that?

Answer 1

in loops like "for a in b", avoid to give the same names to iterator and iterable object.
i suppose there might be a collapse happened, your list was passed to a generator, and then, using the same name, your list was overwritten by each it's element, so after a loop the name 'greatppl' stores only the last of items.
use different name, like:
for greathuman in greatppl:
print greathuman
