Truncate a string without ending in the middle of a word

by

I actually wrote a solution for this on a recent project of mine. I’ve compressed the majority of it down to be a little smaller.

def smart_truncate(content, length=100, suffix='...'):
    if len(content) <= length:
        return content
    else:
        return ' '.join(content[:length+1].split(' ')[0:-1]) + suffix

What happens is the if-statement checks if your content is already less than the cutoff point. If it’s not, it truncates to the desired length, splits on the space, removes the last element (so that you don’t cut off a word), and then joins it back together (while tacking on the ‘…’).
