In Python, if I want to get the first n characters of a string minus the last character, I do:
output = 'stackoverflow'
print output[:-1]
What’s the Ruby equivalent?

I don’t want to get too nitpicky, but if you want to be more like Python’s approach, rather than doing
"StackOverflow"[0..-2]you can do"StackOverflow"[0...-1]for the same result.In Ruby, a range with 3 dots excludes the right argument, where a range with two dots includes it. So, in the case of string slicing, the three dots is a bit more close to Python’s syntax.
