Split string with identical separator

path = '45.63.130.248:15+221.160.226.9:329+101.240.154.40:1197'

nodes = path.split('+')

print nodes

['45.63.130.248:15', '221.160.226.9:329', '101.240.154.40:1197']

path = '45.63.130.248:15*+221.160.226.9:329*+101.240.154.40:1197'

nodes = path.split('*+') # separator can have more than one charactor

print nodes

['45.63.130.248:15', '221.160.226.9:329', '101.240.154.40:1197']

Split string with non-identical separator

ticket_key = '45.63.120.248:1195&221.160.226.9:329^101.240.154.40:1197'
# how about this one? It has 2 diffrent separators '&' and '^'

node1 = ticket_key.split('&')[0]
node2 = ticket_key.split('&')[1].split('^')[0]
node3 = ticket_key.split('&')[1].split('^')[1]

print node1, node2, node3

45.63.120.248:1195 221.160.226.9:329 101.240.154.40:1197

# A more elegent way, is to use the re.split()
import re

ticket_key = '45.63.120.248:1195&221.160.226.9:329^101.240.154.40:1197'

nodes = re.split('[&\^]', ticket_key)
print nodes

['45.63.120.248:1195', '221.160.226.9:329', '101.240.154.40:1197']
