You can browse this part of the forum to find tons of samples which show input in python. Especially the thread "solution to TEST in python".

The "normal" python functions input(), raw_input() work.

If you need faster I/O (some problems show "huge i/o warnings") you can use the sys module and patterns like this:
[bbone=Python3,526]import sys

def main():
for line in sys.stdin.readlines()[1:]:
if line.strip():
num = int(line)
result = num * num - 1
sys.stdout.write('%d\n' % result)

if name == 'main':
main()[/bbone]
//enhanced code //

so here it is storing input of one line in num one by one and then after printing result it goes to next line . m i right >???

Yes.

Please be aware that this primarily is not a site to learn a language. Ther are great tutorials ond documentations available on the www....

ok . thnx...

...of course you can ask questions here anytime.

I inserted an if-clause in the code above which can be useful for spoj problems, because the input files often have empty lines which your code has to handle...
