Following code snipped leads to an IndexError in the last line.
It basically puts EN_cmw into a dict where is a split on '->'.
It avoid the bug you can change the 1 into -1.
(By definition it shouldnt make a difference)

EN_cmw = '''abandonned->abandoned
EN_cmw = EN_cmw.split('\n')
EN_cmw = [string.strip() for string in EN_cmw]

    line.split('->')[0]: line.split('->')[1] for line in EN_cmw

Correction of typo in the last sentence:

To avoid the bug you can change the 1 into -1

IndexError is caused by the fact that split results in an empty list.
