Understanding formatting

[mickandralphscrier]

Hi!

I found a script online that uses the website ipinfo.io to deliver some information about the users IP adress. I'm trying to figure out what this line means:

print ('IP : {4} \nRegion : {1} \nCountry : {2} \nCity : {3} \nOrg : {0}'.format(org,region,country,city,IP))

In context of this here script:

import re
import json
from urllib.request import urlopen

url = 'http://ipinfo.io/json'
response = urlopen(url)
data = json.load(response)

IP=data['ip']
org=data['org']
city = data['city']
country=data['country']
region=data['region']

print ('Your IP detail\n ')
print ('IP : {4} \nRegion : {1} \nCountry : {2} \nCity : {3} \nOrg : {0}'.format(org,region,country,city,IP))

Specifically, what exactly do the numbers represent inbetween the variables? How does the .format do its thing?

Thanks a lot in advance.
