您可以在片段上创建用于更新它的方法，如果该片段已经存在，请使用该方法。

示例：

for index, movies in data.iterrows():
    try:
      c.execute("INSERT INTO movie VALUES (:budget, :homepage, :id, :original_language, :original_title, :overview, :popularity, :release_date, :revenue, :runtime, :status, :tagline, :title, :vote_average, :vote_count)", 
                {'budget': movies['budget'], 'homepage': movies['homepage'], 'id': movies['id'], 'original_language': movies['original_language'], 'original_title': movies['original_title'], 
                 'overview': movies['overview'], 'popularity': movies['popularity'], 'release_date': movies['release_date'], 'revenue': movies['revenue'], 'runtime': movies['runtime'], 
                 'status': movies['status'], 'tagline': movies['tagline'],
                 'title': movies['title'], 'vote_average': movies['vote_average'], 'vote_count': movies['vote_count']})
    except sqlite3.IntegrityError as e:
      pass # ignore SQLite complaints about UNIQUE primary keys


for movie_genres in data['genres']:
    for genres in movie_genres:
      try:
        c.execute("INSERT INTO genre VALUES (:id, :name)", {'id': genres['id'], 'name': genres['name']})
      except sqlite3.IntegrityError as e:
        pass # ignore SQLite complaints about UNIQUE primary keys

希望有帮助！

有什么方法可以替换单个片段的数据而不替换片段？
