That's not a list,if you want only those item in a new list.
lst = ['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81' , '10208, Patrick, Green, 1, 3.95'] >>> lst[:2] ['10015, John, Smith, 2, 3.01', …

slist = ['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81' , '10208, Patrick, Green, 1, 3.95'] mylist = [item.strip() for s in slist for item in s.split(',')] print(mylist) ''' result ... ['10015', 'John', 'Smith', '2', '3.01', '10334', 'Jane', 'Roberts', '4', '3.81', …

>>> lst[:2]
['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81']
To get the output you show.
>>> new_lst = lst[:2]
>>> for data in new_lst:
for item in data.split(', '):
print item
10015
John
Smith
2
3.01
10334
Jane
Roberts
4
3.81
['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81' , '10208, Patrick, Green, 1, 3.95']
there is the list so i want it like
['10015', 'John', 'Smith', '2', '3.01','10334', 'Jane', 'Roberts', '4', '3.81' , '10208', 'Patrick', 'Green', '1, 3.95']
lst = ['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81' , '10208, Patrick, Green, 1, 3.95']
>>> new_lst = []
>>> for data in lst:
for item in data.split(','):
new_lst.append(item)
>>> print new_lst
['10015', ' John', ' Smith', ' 2', ' 3.01', '10334', ' Jane', ' Roberts', ' 4', ' 3.81', '10208', ' Patrick', ' Green', ' 1', ' 3.95']
Ohhhhhhhhhhhhh i had the split function written below the append
Thanks alot for you help
Ok thanks.
If it's a school task deliver this for fun,and ask your teacher to explain it.
>>> sum(map(lambda x: str.split(x, ','), lst), [])
['10015', ' John', ' Smith', ' 2', ' 3.01', '10334', ' Jane', ' Roberts', ' 4', ' 3.81', '10208', ' Patrick', ' Green', ' 1', ' 3.95']
Or try this ...
slist = ['10015, John, Smith, 2, 3.01', '10334, Jane, Roberts, 4, 3.81' , '10208, Patrick, Green, 1, 3.95']
mylist = [item.strip() for s in slist for item in s.split(',')]
print(mylist)
''' result ...
['10015', 'John', 'Smith', '2', '3.01', '10334', 'Jane', 'Roberts', '4', '3.81', '10208', 'Patrick', 'Green', '1', '3.95']

Yes here is list comprehension much better looking,than my (for fun) functional programming style soultion.
Wow snippsat, what does sum() do here?
I thought it would just add up numbers in a list.
>>> lst = [[1,2], [3,4]]
>>> lst
[[1, 2], [3, 4]]
>>> sum(lst, [])
[1, 2, 3, 4]
When use sum() on the outer list and set second argument to an empty list [],default is 0.
Python will concatenate the inner lists,producing a flattened list.
so on the inner list.
>>> [1,2] + [3,4]
[1, 2, 3, 4]
