Question

I have a list of strings like this:

my_list = ['Lorem ipsum dolor sit amet,', 'consectetur adipiscing elit. ', 'Mauris id enim nisi, ullamcorper malesuada magna.']

I want to basically combine these items into one readable string. My logic is as follows:

If the list item does not end with a space, add one
otherwise, leave it alone
Then combine them all into one string.

I was able to accomplish this a few different ways.

Using a list comprehension:

message = ["%s " % x if not x.endswith(' ') else x for x in my_list]
messageStr = ''.join(message)

Spelling it out (I think this is a bit more readable):

for i, v in enumerate(my_list):
    if not v.endswith(' '):
        my_list[i] = "%s " % v
messageStr = ''.join(my_list)

My question is, is there an easier, “more sane” way of accomplishing this?

Answer 1

>>> my_list = ['Lorem ipsum dolor sit amet,', 'consectetur adipiscing elit. ', 'Mauris id en
im nisi, ullamcorper malesuada magna.']
>>> ' '.join(string.strip() for string in my_list)
'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris id enim nisi, ullamcorper
 malesuada magna.'
