I have some data as string which contains list of list of data.

data = "[['asdaddas','asdasdasd'],['asdawdasd','asdwdefe']]"

As you can see that this is nested list in string not of type(list()).

I have tried manually using online-json-formatter and copying data from the result and pasting it for assigning it to some variable. like:

data = [['asdaddas','asdasdasd'],['asdawdasd','asdwdefe']]

but here is the issue that this is not how i will be doing it on all iterations. There should be some code to convert it from above mention string type data to list type data.

I hope you guys can help me!

Thanks in advance.

Look into using AST `eval()` in Python. – Tim Biegeleisen Jan 12 '23 at 06:17
I would only use `eval`, if there is no other way (since it may be dangerous on untrusted input). In your example, `json.loads` suffices (needs `import json`) – Lorenz Hetterich Jan 12 '23 at 06:17
You can convert it to valid json by changing ' to " and enclose at {}. After that use json.loads(text) – Alpensin Jan 12 '23 at 06:19
you're right, replacing `'` with `"` is needed, but the enclosing in `{}` is not required. – Lorenz Hetterich Jan 12 '23 at 06:22
@LorenzHetterich Yeah, you're right. Checked that. – Alpensin Jan 12 '23 at 06:23
Thanks everyone it is solved. All the three solutions by you guys worked for me. Thanks a lot. @ti – Piyush Jain Jan 24 '23 at 11:58
