Try:

import ast
list_ = ast.literal_eval(x)
print(list_)

output:

['aaa1', 'aaa2', 'aaa3', 'aaa4', 'aaa5', 'aaa6', 'aaa7', 'aaa8']

Is ast a common package? What does it stand for? Thanks – burcak Feb 05 '21 at 06:00
Yes, it comes with python. It stands for Abstract Syntax Trees. See [docs](https://docs.python.org/3/library/ast.html). It is the correct way to handle these types of problems. – sarartur Feb 05 '21 at 06:02

you can use this split method

y=x.split(,)

but it will not split perfectly first you should remove the bracket and spaces like this

x = x.replace('[','')
x = x.repalce(']','')
x = x.replace(' ','')
x = x.replace("'","")
y = x.split(',')

this will do yours work

You can try the following

x="['aaa1', 'aaa2', 'aaa3', 'aaa4', 'aaa5', 'aaa6', 'aaa7', 'aaa8']"

y = eval(x)

Here :
x is <class 'str'>
y is <class 'list'>

You can use eval method. It is simpler!

x="['aaa1', 'aaa2', 'aaa3', 'aaa4', 'aaa5', 'aaa6', 'aaa7', 'aaa8']"
print(eval(x))

Output: ['aaa1', 'aaa2', 'aaa3', 'aaa4', 'aaa5', 'aaa6', 'aaa7', 'aaa8']
