问题
当我运行以下文件时python launcher
没有任何反应:
#! /usr/bin/python
import addressbook_pb2
import sys
# Iterates though all people in the AddressBook and prints info about them.
def ListPeople(address_book):
for person in address_book.person:
print "Person ID:", person.id
print " Name:", person.name
if person.HasField('email'):
print " E-mail address:", person.email
for phone_number in person.phone:
if phone_number.type == addressbook_pb2.Person.MOBILE:
print " Mobile phone #: ",
elif phone_number.type == addressbook_pb2.Person.HOME:
print " Home phone #: ",
elif phone_number.type == addressbook_pb2.Person.WORK:
print " Work phone #: ",
print phone_number.number
# Main procedure: Reads the entire address book from a file and prints all
# the information inside.
if len(sys.argv) != 2:
print "Usage:", sys.argv[0], "ADDRESS_BOOK_FILE"
sys.exit(-1)
address_book = addressbook_pb2.AddressBook()
# Read the existing address book.
f = open(sys.argv[1], "rb")
address_book.ParseFromString(f.read())
f.close()
ListPeople(address_book)
