No output for the code to read emails

[avani9659]

Hello,
I've tried the code given below to read emails using poplib but I'm unable to get the output.

import poplib
import string, random
import io, email

def readMail():
	server = 'pop.gmail.com'
	user = 'user_email'
	password = 'password'

	srv = poplib.POP3_SSL(server)
	srv.user(user)
	srv.pass_(password)

	for i in range(0,5):
		id, size = string.split(items[i])
		resp, text, octets = srv.retr(id)
		text = string.join(text,"\n")
		file = io.StringIO(text)
		message = email.Message(file)
		for k,v in message.items():
			print(k, "=", v)

readMail()
