python - remove a dictionary from a list if dictionary key equals a certain value

i want to know how to remove a specific dict from this list if user status equals "offline" and order type equals "buy" (iterating over it with for loop and modifying the list while iterating produces an exception because of the list pointer)

mylist = [
           {
             "user": {"status": "offline"}, 
             "order_type": "buy"
           },
           {
             "user": {"status": "online"},
             "order_type": "sell"
           }
         ]

You can re-create the list without undesired elements:

mylist = [key_values for key_values in mylist if key_values['user']['status'] != 'offline']

(*) do not name your variables using reserved keywords.

seq = [
         {
           "user": {"status": "offline"}, 
           "order_type": "buy"
         },
         {  "user": {"status": "online"},
            "order_type": "sell"
         }
       ]

for _ in seq:
    print _
    if _['user']['status'] == 'offline':
        seq.remove(_)

print seq

In case if you're looking for in place removal.

output: [{'user': {'status': 'online'}, 'order_type': 'sell'}]
