Access list dict pass via a tuple of indexes

def search_index(obj, itero):
    try:
        return search_index(obj[next(itero)], itero)
    except StopIteration:
        return obj

a = [{"name":"someone", "age":23}]
s = (0, 'name')

result = search_index(a, iter(s))
# >>> result = 'someone'

#If you want to convert "[0]['name']" to (0, 'name') you can try this:

import re
reg = re.findall(r'\[(\d*?)\]|\[\'(\w*?)\'\]', "[0]['name']")
s = [int(index[0]) if not index[1] else index[1] for index in reg]
# [0, 'name']
