[Pyparsing] Reading n words

[Andreas M. <and...@gm...>]

Hello, 

I'm trying to parse a string like '3 foo bar baz', where the
number in the string specifies the number of the following words.
Is there a more elegant way to achieve this than with the following
code? 

Ciao
Andreas



from pyparsing import *

def foo(st):
    p1 = Word(nums)
    n = p1.parseString(st)[0]
    p2 = Literal(n) + Word(alphas)*int(n)
    print p2.parseString(st)

foo('1 foo')
foo('2 foo baz')
foo('3 foo bar baz')
