How python lists are filtered using a similar method of mongodb aggregation $group

[
     {"_id": ObjectId("5abb4f9ca7e2c54c757b3e48"),
      "amount": 8400,
      "buyerEmail": "otzYzwMh24edWk8NxSJOqCSZREe0",

how to integrate the same uid and display only the elements of uid real from rechargeDate?
$group similar to mongodb aggregation
ideal result:

[
    {"uid":xxxxxxxxxxxxxxxx:
        [
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
        ]
    },
        {"uid":xxxxxxxxxxxxxxxx:
        [
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
            {
                "real":xxx,
                "from":xxx,
                "recharge":xxx,
            },
