python 將使用 try 創建的計算值保存到列表中，除了 function

Question

嗨，我有這些嵌套字典和列表作為我的數據。 這是兩場比賽的摘要。

  my_stats = [
     {'_id': 'GLEvHIL2020031419A', 'stats': 
     {'data': [
     {'area': 'B1', 'key': 'Lineouts', 'possession': 'against', 'second': 7, 'endSecond': 27, 
     'time': '2020-03-14T12:00:43', 'Lineout Presentation': 'Scrappy', 'Lineout Errors': 'Lost'},
     {'area': 'D2', 'key': 'Lineouts', 'possession': 'for', 'second': 344, 'endSecond': 383, 'time': 
      '2020-03-14T12:53:43', 'Lineout Presentation': 'Goodball', 'Lineout Errors': 'Lost'},
     {'area': 'A1', 'key': 'Lineouts', 'possession': 'for', 'second': 354, 'endSecond': 358, 'time':

     {'_id': 'HJSvMON2020031419A', 'stats': 
     {'data': 
     [{'area': 'C1', 'key': 'Kick Off', 'possession': 'against', 'second': 0, 'endSecond': 6, 'time': 
     '2020-03-14T12:00:06', 'Kick Off Fielded': 'Unsuccessful'},
     {'key': 'Passive Tackle', 'possession': 'against', 'second': 9, 'time': '2020-03-14T12:00:09', 
     'value': 9, 'subMetric': 3, 'rtp': []}, 
     {'area': 'D1', 'key': 'Rucks', 'possession': 'against', 'second': 9, 'endSecond': 19, 'time': '2020- 
      03-14T12:00:19'}, 
     {'area': 'D1', 'key': 'Lineouts', 'possession': 'for', 'second': 33, 'endSecond': 45, 'time': '2020- 
     03-14T12:00:45', 'Lineout Formations': '5 Man', 'Lineout Area Of Throw': 'Front', 'Lineout 
     Contested': 'Contested', 'Lineout Presentation': 'Scrappy', 'Lineout Errors': 'Lost', 'Maul Meters': 
     '5'}, 
     {'key': 'Neutral Tackle', 'possession': 'for', 'second': 45, 'time': '2020-03-14T12:00:45', 'value': 
     1, 'subMetric': 2, 'rtp': [{'key': 'Defender in Position', 'possession': 'for', 'second': 49, 
    'time': '2020-03-14T12:00:49', 'value': 1, 'subMetric': None}]},
     {'area': 'D1', 'key': 'Rucks', 'possession': 'for', 'second': 47, 'endSecond': 50, 'time': '2020-03- 
     14T12:00:50'}, 
     {'key': 'Defender in Position', 'possession': 'for', 'second': 49, 'time': '2020-03-14T12:00:49', 
     'value': 1, 'subMetric': None, 'rtp': []}, 
     {'key': 'Passive Tackle', 'possession': 'for', 'second': 51, 'time': '2020-03-14T12:00:51', 'value':       
     7, 'subMetric': 3, 'rtp': [{'key': 'Defender in Position', 'possession': 'for', 'second': 53, 
     'time': '2020-03-14T12:00:53', 'value': 7, 'subMetric': None}]}, 
     {'key': 'Tackle Assist', 'possession': 'for', 'second': 52, 'time': '2020-03-14T12:00:52', 'value': 
     8, 'subMetric': None, 'rtp': [{'key': 'Defender in Position', 'possession': 'for', 'second': 53, 
     'time': '2020-03-14T12:00:53', 'value': 8, 'subMetric': None}]}, 
     {'key': 'Defender in Position', 'possession': 'for', 'second': 53, 'time': '2020-03-14T12:00:53', 
     'value': 8, 'subMetric': None, 'rtp': []}]}}]

我需要編寫一個 function 來計算每場比賽贏得的爭邊球並保存游戲名稱 (_id) 以及每場比賽的 Goodball、Scrappy 和 Drive 爭邊球的數量。

 Lineouts = []
    Games = []
    def Our_Lineouts_Won():
            global Lineouts
            Lineouts = (0)
            
            for l in my_stats:
                t=(l['stats']['data'])
                print(l['_id'])
                Games.append(str(l['_id']))
                
                for i in t:
                     
                     try:
                         if ((i['key']) == 'Lineouts' and (i['possession'])== 'for'and ((i[('Lineout 
                         Presentation')])==  'Off the Top'  or 'Scrappy' or  'Drive'  )):
                                       
                            Lineouts += 1 
                            
                     except KeyError:
                        pass  
        
    Our_Lineouts_Won()

我想要的結果是一個字典，其中鍵是_id，值是計算出來的 Our_Lineouts_won()。

我嘗試將 Lineouts 附加到列表中。

請協助。

Answer 1

這是我設法回答我的問題的方法。 我創建了一個字典 lpg... 是每場比賽陣容的縮寫。 然后我將所有 _id 附加到列表 Games。

之后，我嘗試了嘗試，如果沒有捕獲到 Lineout 演示文稿，則阻止代碼中斷。

每場比賽都會添加每個符合標准的邊線球員，並保存在變量 L1 下。

然后我更新了我的空字典

lpg.update({games:L1})

如您所見，我使用 df = pd.DataFrame(list (lpg.items())) 從字典中創建了 dataframe。

Lineouts = []
Games = []
lpg = {}
def Our_Lineouts_Won():
        global Lineouts
        global lpg
        Lineouts = (0)
        lpg = {}
        for l in my_stats:
            t=(l['stats']['data'])
            games = (l['_id'])
            Games.append(str(l['_id']))
            #print (games)
            
            for i in t:
                 
                 try:
                     if ((i['key']) == 'Lineouts' and (i['possession'])== 'for'and ((i[('Lineout Presentation')])==  'Off the Top'  or 'Scrappy' or  'Drive'  )):
            #if ((i['key']) == 'Lineouts' and (i['possession'])== 'for'and ((i[('Lineout Presentation')])==  'Off the Top'  or (i[('Lineout Presentation')])==  'Scrappy' or (i[('Lineout Presentation')])==  'Drive'  )):
                        
                         Lineouts += 1
                        
                 except KeyError:
                    pass  
            
            L1=(str(Lineouts))
            
            lpg.update({games:L1})
            
            
            
        
            
            Lineouts = (0)
               
            
            
        #print (lpg)   
             
       
Our_Lineouts_Won()
