how can I convert a string representation of a list of lists to a list data structure in python. For example if I have a string k:

k="['A',['B','C'],'D']"

The desired output I want is a list like below

 ['A',
['B','C'],
'D']

CodePudding user response：

Use ast.literal_eval():

>>> import ast
>>> ast.literal_eval(k)
['A', ['B', 'C'], 'D']

CodePudding user response：

eval is a built-in python function that parses the given string argument and evaluates it as an expression.

>>> k = "['A',['B','C'],'D']"
>>> print(eval(k))
['A', ['B', 'C'], 'D']
