String of list to list Python
How to convert string representation of python list to list pythonThis tutorial is written for Python 3, but it also works for Python 2 Show Assume you have a string representation of list like this: And you to convert s string to Python list like this: s_list = ["hello", "world", 1, 2, 3]There are some solutions to do that. Using literal_eval function from ast module. #>>> import ast >>> s = '["hello", "world", 1, 2, 3]' >>> s_list = ast.literal_eval(s) >>> s ["hello", "world", 1, 2, 3]ast.literal_eval(node_or_string) safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and None. That means you can also use ast.literal_eval() to convert a string representation of tuple, dict, set to Python tuple, dict, set Using json module #You can also use json module to achieve the same result. json module a is a better solution whenever there is a stringified list of dictionaries. The json.loads(s) function can be used to convert it to a list. Similarly >>> s = '[ "hello","world","1", "2", "3", {"id": "45"}]' >>> json.loads(s) ["hello","world","1", "2", "3", {"id": "45"}] |
