Furthermore Ruby has a pretty nice convention (sadly not used enough
I think) taken from Scheme where it's possible to postfix a method
name with "!" (note: the "!" is part of the name, there's no magic)
to indicate that this method modifies the object it's called on
rather than simply returning stuff.
Another oddity i did not like at first but must admit is growing on me
vector.reverse --> returns a new reversed vector
vector.reverse! --> modifies the instance vector in-place
Of course in python you would do...
vector.reverse --> in-place
vector.reversed --> in-place
how to reverse a string in python? must i usa a temp? like:
>>> s = "ciccio"
>>> l = list(s)
>>> l.reverse()
>>> s = "".join(l)
>>> s
'oiccic'
>>>
???
Use slicing with a step of -1:
>>> s = "ciccio"
>>> s[::-1]
'oiccic'
