Parse Array Parse Array
English FR RU

In this task you you already have the solution. The problem is that it has a bug and you must try to find and fix it. " import ", " exec " and " eval " don't work for this task.

You are given a string that contains a list with integers or nested lists. The integers could have single plus or minus sign before them. If the input string does not contain an array, then raise ValueError . For an incorrectly formatted string -- raise ValueError . Elements of the array are separated by commas.

Input: A string.

Output: The list with nested lists or integers.


parse_array("[1, 2, 3]") == [1, 2, 3]
parse_array("[[1], 2, 3]") == [[1], 2, 3]
parse_array("[-3, [-2, 0], 10]") == [-3, [-2, 0], 10]

How it is used: This task is designed for you to show off your bug hunting skills. The parser code itself can be modified and improved to work as part of a larger more complex parsing system.
