Convert List to String and back to List Python 3

Question

If I type:

>>> list(str([0, 0, 0]))

I get: ['[', '0', ',', ' ', '0', ',', ' ', '0', ']']

How would I make it so that I get [0, 0, 0] instead?

Why list > string > list? What's the purpose? – schrodingerscatcuriosity Aug 30 '18 at 18:53 — schrodingerscatcuriosity, Aug 30 '18 at 18:53

If what you want to do is cast every item into a string. Do this:

>>> orig_list = [0, 0, 0]
>>> new_list = [str(item) for item in orig_list]

>>> new_list
['0', '0', '0']

Output should be `[0, 0, 0]`. Not `['0', '0', '0']` – Nouman Aug 30 '18 at 19:01
I wrote 'if' that's what the OP wants to achieve. It seemed like a slightly nonsensical question – N Chauhan Aug 30 '18 at 19:04

It is not a good idea to use in a production code but you can use

eval("".join(list(str([0, 0, 0]))))

You can use list comprehension like this:

my_str = str([0, 0, 0])
my_list = [int(s) for s in my_str.replace('[', '').replace(']', '').split(',')]

Now you have:

>>> my_str
'[0, 0, 0]'
>>> my_list
[0, 0, 0]
