Some basic questions

I just began writing Python today and have a few basic questions:
How can I read a single character from the standard input without consuming
any more input?
Is there any way to write a boolean function? I wanted to write a simple
is_alpha function (which may be in the standard library but I'm leanring),
and this is what I came up with:
def is_alpha(c) :
letters = re.compile("[a-zA-Z]")
Instead of checking for true or false I check to see if None is returned,
but that seems a little kludgy.
How can I print to standard out without printing a newline? It seems that
the print statement always adds a newline and I haven't found any other
outputting functions yet.
