我有這個清單[('[]',), ("['843997058062483456', '774956001223770122', '645597259458674707']",), ('[]',), ('[]',)]，我想把它變成[[], ['843997058062483456', '774956001223770122', '645597259458674707'], [], []]
任何想法？

您可以在嵌套串列推導中使用：ast.literal_eval
>>> from ast import literal_eval
>>> xs = [('[]',), ("['843997058062483456', '774956001223770122', '645597259458674707']",), ('[]',), ('[]',)]
>>> extracted = [literal_eval(s) for t in xs for s in t]
>>> extracted
[[], ['843997058062483456', '774956001223770122', '645597259458674707'], [], []]

import json
original = [('[]',), ("['843997058062483456', '774956001223770122', '645597259458674707']",), ('[]',), ('[]',)]
def transform(lst):
return [json.loads(t[0].replace("'", '"')) for t in lst]
print(transform(original))
