I was wondering how I could change a list written as a string, such as ‘[1,[2,[]],[3,[]]]’ into an actual python list like [1,[2,[]],[3,[]]]. Is there any algorithm for this?

3`eval("[1,[2,[]],[3,[]]]")` – Woody Pride Dec 04 '17 at 19:35

@WoodyPride `eval` is dangerous because it will execute code in the input. – Skippy le Grand Gourou Jun 19 '19 at 09:27

Assign your value to a variable then call the variable.split() it defaults to comma delimited which in your instance would result in list['[1,[2,[]],[3,[]]]']
another example of this could be this:
a = "test, 1, testing2, alpha, beta, Zulu, 23"
a.split()
Result: ['test,', '1,', 'testing2,', 'alpha,', 'beta,', 'Zulu,', '23']

sorry I forgot that split is default space delimited if you do a.split(",") you end up with a comma delimited python list – Mike Pineau Dec 04 '17 at 19:34
