#zero.py
#very simple python function to reset all numbers in selection to 0 

# we'll start by replacing only one line

import sys
import re

# get the selection into python
# input[x] now hold line x as a string
input = sys.stdin.readlines()

# dummy replacement value for now
# change this to an arg next
new_str	=	'0'

# make the reg ex for all number text objects
my_reg = re.compile( '[0-9]+' )

# need to count how many lines are in the block.
for i in range( len(input) ):

	# turn all the '1's into '0's
	new_line = my_reg.sub( new_str, input[i] )

	# print out the new string
	print new_line,
