Because print is a statement, not a function.  Map must take
a function.  You'd have to do this to get the effect you want,
though there are better ways and this one just plain stinks:

def printit(item):
    print item

map(printit, ['Have','a','reasonably','nice','day.'])

Using the form "print('a string')" is perhaps poor style, since
it suggests print is a method.  Same applies to return, which is
also a statement (as in C, where people also get it wrong).
