Matching Pure Numeric and '' with Python re

[Wijaya Edward]

Hi,

Given this list:

list = ['0123', '1A34' , '333-' , '' ]

I want to match only this element
'0123' (pure numeric) and '' (empty element).

Why this construct doesn't work?

p = re.compile("''+|[0-9]+")
m = p.match(word)
if m:
print word,

Namely it doesn't print 0123 and ''.
What's wrong with my regex?
