Could you explain me how does it work, pls?
==============================
r = ''
r is an empty string
for c in 'abcd':
c takes the value of each letter in turn
r = c + r
strings can be added such that the result is the
concatenation of the two strings. So in this case:
r becomes the sum of its old value and the current value of c
repeat for the next value of c.
If that doesn't help then tell us which bit(s) of it you
don't understand.
HTH,
