How to replace substring with another substring (by index from..to)

Question

How I can replace substring from some character to another by other string?

first = 4
last = 11
replacement = '...'
'show me the money'.replace_part(first, last, replacement)
# => 'show...money'

Could there be a better version of title? In its current form it's not very findable, I'm afraid. But I don't have any alternatives. :/ — Sergio Tulentsev
