python ---處理字典方法，將相同的key進行合並，value值用列表展示

test=[
    {"url":"/order.html","code":"post"},
    {"url":"/order.html","code":"get"},
    {"url":"/order.html","code":"put"},
    {"url":"/order.html","code":"delete"},
    {"url":"/index.html","code":"post"},
    {"url":"/index.html","code":"get"},
    {"url":"/index.html","code":"put"},
    {"url":"/login.html","code":"put"},
    {"url":"/login.html","code":"get"},
    {"url":"/login.html","code":"post"},
      ]
handler={}
for item in test:
    if item['url'] in handler:
        handler[item["url"]].append(item["code"])
    else:
        handler[item["url"]] = [item["code"]]  #用列表方式接收

print(handler)

#{'/order.html': ['post', 'get', 'put', 'delete'], '/index.html': ['post', 'get', 'put'], '/login.html': ['put', 'get', 'post']}
