Python - String to list

Question

I need cast a list to a string and get back the string to a list. There's a python way to make this behavior?

l1 = ['aa','bb','cc']
s = str(l1)
l2 = cast_string_to_list(s)
print l2
"['aa','bb','cc']"

Answer 1

Use a serialization library like json:

import json

l1 = ['aa','bb','cc']
s = json.dumps(l1)
l2 = json.loads(s)

print s
print l1 == l2
