, wie zwei Liste fusionieren dict mit

Question

list1 = [{'id': 1, 'data1': 'Chris', 'data2': ['Salt', 'Texas']}, 
     {'id': 2, 'data1': 'Smith', 'data2': ['Melbourne', 'Victoria', 'Sydney']}] 

list2 = [{'id': 1, 'data1': ['Royne','Nick'], 'data2': 'US'}, 
     {'id': 2, 'data1': ['Harry','Jorge','Marie'], 'data2': 'Australia'}] 

ich diese beiden Liste zusammenführen möchten und erhalten:

merged_list = [{'id': 1, 'data1': ['Chris','Royne','Nick']', 'data2': ['US','Salt', 'Texas']}, 
       {'id': 2, 'data1': ['Smith','Harry','Jorge','Marie'], 'data2': ['Australia','Melbourne', 'Victoria', 'Sydney']}] 

Answer 1

def merge_dicts(list1, list2): 
    merged_list = [] 
    for i, (d1, d2) in enumerate(zip(list1, list2)): 
     merged_list.append({}) 
     for d in [d1, d2]: 
      for k, v in d.items(): 
       if k in merged_list[i]: 
        if v not in merged_list[i][k]: 
         if isinstance(v, list): 
          merged_list[i][k].extend(v) 
         else: 
          merged_list[i][k].append(v) 
       else: 
        if isinstance(v, list): 
         merged_list[i][k] = v 
        else: 
         merged_list[i][k] = [v] 
     for k, v in merged_list[i].items(): 
      if len(v) == 1: 
       merged_list[i][k] = v[0] 
      else: 
       merged_list[i][k] = v 
    return merged_list 

>>> merge_dicts(list1, list2) 
[{'id': 1, 'data1': ['Chris', 'Royne', 'Nick'], 'data2': ['Salt', 'Texas', 'US']}, {'id': 2, 'data1': ['Smith', 'Harry', 'Jorge', 'Marie'], 'data2': ['Melbourne', 'Victoria', 'Sydney', 'Australia']}]
