这段代码中出现KeyError: 'username'

在您提供的代码片段中，`KeyError: 'username'` 错误可能出现在 `add_data` 函数中的某些部分，因为并不是所有的字典都包含了 `'username'` 这个键。具体来说，以下这些数据结构没有 `'username'`：

- `accounts_data`
- `movies_data`
- `series_data`
- `seasons_data`
- `episodes_data`
- `games_data`
- `has_g_data`
- `avail_language_data`
- `game_type_data`
- `cars_data`
- `weapons_data`
- `check_point_data`

为了防止这种错误，可以在 `add_data` 函数中检查每个数据结构是否包含 `'username'` 键，然后再进行操作。以下是修改后的 `add_data` 函数：

def add_data(data, num=100):
    for i in range(num):

# 调用函数添加数据
add_data(accounts_data)
add_data(login_log_data)
add_data(users_data)
add_data(watch_m_data)
add_data(watch_s_data)
add_data(movies_data)
add_data(series_data)
add_data(seasons_data)
add_data(episodes_data)
add_data(games_data)
add_data(download_data)
add_data(has_g_data)
add_data(avail_language_data)
add_data(game_type_data)
add_data(belong_g_data)
add_data(cars_data)
add_data(weapons_data)
add_data(check_point_data)
add_data(own_c_data)
add_data(own_w_data)
add_data(resources_data)

通过这种方式，可以避免在不包含 `'username'` 键的数据结构上调用该键时引发 `KeyError`。
