Thanks (and to Grant). IO seems to be the canonical example. Where
some languages would force one to write
c = sys.stdin.read(1)
while c == ' ':
c = sys.stdin.read(1)
Python opts for
while True:
c = sys.stdin.read(1)
if c != ' ': break
This loop would be the archetypical do..while or repeat...until to me.
do
c = sys.stdin.read(1)
while c== ' '
-or-
repeat
c = sys.stdin.read(1)
until c != ' '
is the most clear to me - and in fact this "while True; do something;
break" thingy is just an idiom to fake a do..while loop in Python.
C does have it, for example, and it is way better like this than the
abuse of assignment and comma operator in the condition.
