Need Help with the BeautifulSoup problem, please

[seaspeak]

I need to replace all tag  with  after ■. But the result from 
below is '■   D / '
Can you explain what I did wrong, please.

s = '■A B C D / '
soup = BeautifulSoup(s)
for i in soup.find_all(text='■'):
tag = soup.new_tag('span')
tag['style'] = 'REPLACE'
for ii in i.find_next_siblings():
if ii.name=='font' or str(ii).lstrip('')[0:1]=='/':
break
else:
if ii.name=='b':
tag.string=ii.string
print(ii.replace_with(tag))
print(soup)

the point is the result seems wrong. I don't know if that is my problem.
I simplify the code to emphasize the problem, there's no way an editor can do 
what I wanna do.

I think it's my fault, thanks

should I transfer 'iterators' between functions?

[seaspeak]

take the following as an example, which could work well.
But my concern is, will list 'l' be deconstructed after function return? and 
then iterator point to nowhere?

def test():
l = [1, 2, 3, 4, 5, 6, 7, 8]
return iter(l)
def main():
for i in test():
print(i)

how to iterate all sub-element in a list

[seaspeak]

a list like L = [[1, 2], [3, 4, 5], [6]], which has
random numbers of list, which has random numbers.

How do I get another list m = [1, 2, 3, 4, 5, 6] in a succinct way? ( or 
iterate them)
I should provide my own solution, but I really can't come out with one.

thanks. a keyword is all I need.
It is not homework. It is a common problem I guess.
