I have a list and I have the two list elements start:and end:. Between these two there is an undefined number of elements that I would like to join to the start element.
Also, end: can have different names but it always starts with end:. This is my list
sth_list = ['name: michael', 'age:56', 'start:','','something','is','happening','end:', 'anything could be here:', 'some other things:', 'more things:']
and I would like to get this
['name: michael', 'age:56', 'start: something is happening', 'end:', 'anything could be here:', 'some other things:', 'more things:']
what I have so far is this. But it only gives me the joined elements between start and end but I would like to have the full list as above.
''.join([element for n, element in enumerate(sth_list) if ((n>sth_list.index("start:")) & (n<sth_list.index([e for e in sth_list if e.startswith('end')][0])))])
Get the indexes of start: and end:. Then you can join them and use slice assignment to replace that part of the list with the result.
start = sth_list.index('start:')
end = min(i for i, s in enumerate(sth_list) if s.startswith('end:'))
sth_list[start:end] = [' '.join(sth_list[start:end])]
Note that this only works if there's just one start:/end: pair in the list.
