I'm recently tring to make a python code to convert a string to array.For example:'[[M,,[10,20]],[F,,[7,9]]]' to [['M','',['10','20']],['F','',['7','9']]]
The reason I need it is that I am importing data from excel, which contains arrays in some of the cells, but I have absolutely no idea how to do that, and I would be very grateful if anyone could give me some hint.
I tried to ask chatGPT, but it gave me a code that did not work. Here is the code:
def parse_string(s): result = [] current_list = [] i = 0 while i < len(s): char = s[i] if char == '[': inner_result, remaining_string = parse_string(s[i + 1:]) current_list.append(inner_result) i += len(inner_result) + 2 elif char == ']': result.append(current_list) return result, s[i + 1:] elif char == ',': if i > 0 and s[i - 1] == ',': current_list.append('') i += 1 elif char.isalnum() or char == '.': j = i while j < len(s) and (s[j].isalnum() or s[j] == '.' or s[j] == '-'): j += 1 current_list.append(s[i:j]) i = j else: i += 1 return result, ''string = '[[M,,[10,20]],[F,,[7,9]]]'result, _ = parse_string(string)print(result)And the result would be like: [[[[[['M', '', [['10', '20']], '20']], '', [['10', '20']], '20']], '', [['10', '20']], '20']]
