python 循环创建多个字典

a=['oc2P70Ph14EBiLrX3jI-c138f4tg','oc2P70Gt9duc-1Km4WE4FbxUsHpU','oc2P70MfrRM5lYRVI1d1fthWh3qM','oc2P70FqFlOXON3lQsbtntY2_0Sw',
'oc2P70DTCD3mzLrHVOAhyT0nWtZY']
怎么样创建多个字典形成这样的形式
{"algo_type": "XGB","scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure","request_id": "e24a15cf","user_id": "oc2P70Ph14EBiLrX3jI-c138f4tg" }
{"algo_type": "XGB","scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure","request_id": "e24a15cf","user_id": "oc2P70Gt9duc-1Km4WE4FbxUsHpU" }
{"algo_type": "XGB","scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure","request_id": "e24a15cf","user_id": "oc2P70MfrRM5lYRVI1d1fthWh3qM" }
{"algo_type": "XGB","scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure","request_id": "e24a15cf","user_id": "oc2P70FqFlOXON3lQsbtntY2_0Sw" }
{"algo_type": "XGB","scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure","request_id": "e24a15cf","user_id": "oc2P70DTCD3mzLrHVOAhyT0nWtZY" }

a = ['oc2P70Ph14EBiLrX3jI-c138f4tg', 'oc2P70Gt9duc-1Km4WE4FbxUsHpU', 'oc2P70MfrRM5lYRVI1d1fthWh3qM',
     'oc2P70FqFlOXON3lQsbtntY2_0Sw',
     'oc2P70DTCD3mzLrHVOAhyT0nWtZY']
n = 1
for i in a:
    s = 'dic'.join(str(n))
    s = {"algo_type": "XGB", "scene_id": "child_purchase", "algo_version": "20210930", "bid": "wesure",
         "request_id": "e24a15cf"}
    s["user_id"] = i
    n += 1
    print(s)
