Perhaps I do not understand sxrange / xsrange correctly. The
reference manual entries for them seem to be similar. Is
there a difference? (If one is just an alias for the other,
it would be best to say so. If they are different, the reference
manual needs to emphasize the difference.)
Also the reference manual entry for
sage.misc.misc.sxrange
has the note
: This function is called xsrange to distinguish it from the builtin
Python xrange command.
Should it say "sxrange" rather than "xsrange"?
Finally here is my attempt to use sxrange (xsrange
gives similar output):
e = 1
while true:
print Integer(10^e)
for i in sxrange(Integer(2),Integer(10^e)):
if i == 3:
break
e += 1
gives
10
100

for k in xrange(icount):
OverflowError: long int too large to convert to int
I really want an iterator for the "for i in ..." loop.
Is this a bug? Is there a better way to do what I want?
