I have a list of strings:
['Hello Yes', 'Good Now Order', 'Been There Before', 'Because']
I want to rewrite this as:
['Hello\nYes', 'Good\nNow\nOrder', 'Been\nThere\nBefore', 'Because']
So the \n goes into every space except the beginning or end of the string.
I have tried .split(' ') inside a for loop, but that gets messy and then unsure how to rejoin at the end.
You can try the following comprehension that uses the split and join approach you are suggesting:
l = ['Hello Yes', 'Good Now Order', 'Been There Before', 'Because']
l_new = ['\n'.join(s.split()) for s in l]
# this would replace any sequence of whitespace by a single line break
or perhaps more readable and to the point, using str.replace:
l_new = [s.replace(' ', '\n') for s in l]
# this will replace all and only space characters
Try a list comprehension (this returns a new list with every element the same as in the old one, but with spaces replaced with linebreaks):
[element.replace(' ', '\n') for element in ls]
where ls is your list.
Alternatively, you could do a for-loop, using the replace method.
l = ['Hello Yes', 'Good Now Order', 'Been There Before', 'Because']
list(map('\n'.join, map(str.split, l)))
# ['Hello\nYes', 'Good\nNow\nOrder', 'Been\nThere\nBefore', 'Because']
str.replace
