P.S : if you are new to python and don't expect to use external libraries for the next months (one year?) you might consider to start directly with python 3.x. > Also if I want to enter two numbers 'a' and b such that while entering > them through the keyboard > there is a space between the two... > > For example:>>>Enter two numbers: > > .....12 15 > > Can I use input( ) such that 12 gets accepted in 'a' and 15 in 'b'???? > > I mean how to handle spaces???/ For instance: map( int, raw_input.split() ) splits the input string using blanks as separator, then try to convert each piece in an integer and returns a list of integer. Of course if the input string is not a list of integer you get an exception. You could also do: a, b = map( int, raw_input.split() ) but in this case you get an exception also if the input strings cobntains less or more than two integers.
