How to only interact with objects that are after specific object value in Json using Python?-CodePudding

I'm collecting data that is added to a JSON sequentially, but since they are all added together, they don't come well separated, so I need to get around this difficulty.

My JSON follows this pattern:

{
    "content": {
      "matchFacts": {
        "events": {
          "events": [
            {
              "type": "Substitution",
              "time": 33
            },
            {
              "type": "Card",
              "time": 34
            },
            {
              "type": "Goal",
              "time": 38            
            },
            {
              "type": "Card",
              "time": 43            
            },
            {
              "type": "AddedTime",
              "time": 45
            },
            {
              "type": "Goal",
              "time": 45
            },
            {
              "type": "Half",
              "time": 45
            },
            {
              "type": "Substitution",
              "time": 46
            },
            {
              "type": "Substitution",
              "time": 58
            },
            {
              "type": "Substitution",
              "time": 58
            },
            {
              "type": "Goal",
              "time": 71
            },
            {
              "type": "Substitution",
              "time": 74
            },
            {
              "type": "Substitution",
              "time": 74
            },
            {
              "type": "Substitution",
              "time": 77
            },
            {
              "type": "Substitution",
              "time": 77
            },
            {
              "type": "Substitution",
              "time": 77
            },
            {
              "type": "Substitution",
              "time": 83
            },
            {
              "type": "AddedTime",
              "time": 90
            },
            {
              "type": "Card",
              "time": 90
            },
            {
              "type": "Half",
              "time": 90
            }
          ]
      }
    }
  }
}

Let's say I need to collect only the "type": "Goal" that are before the first "type": "Half" appears, so I do it like this:

search_goals = response_json['content']['matchFacts']['events']['events']
goals_ht = 0
for event in search_goals:
    if (event['type'] == 'Half'):
        break
    elif (event['type'] == 'Goal'):
        goals_ht  = 1

But what about when I need to collect only "type": "Goal" that are AFTER the first "type": "Half", how should I proceed?

CodePudding user response：

Given your structure, a possible solution is to create a False flag that flips to True once a Half event is reached, then simply check for that flag when doing something to the Goal events:

search_goals = response_json['content']['matchFacts']['events']['events']

reached_ht = False
for event in search_goals:
    if event['type'] == 'Half':
        reached_ht = True
    elif event['type'] == 'Goal' and reached_ht:
        # ...
