Question

我正在尝试从数据框中的选项中提取大小和颜色，并且它与下面的代码部分兼容-

def unnest(df, col, col2,reset_index=False):
 col_flat = pd.DataFrame([[i, x]
                  for i, y in df[col].apply(list).iteritems()
                      for x in y ], columns=['I', col]
                       )
 col_flat = col_flat.set_index('I')
 df = df.drop(col, 1)
 df = df.merge(col_flat, left_index=True, right_index=True)

 if reset_index:
     df = df.reset_index(drop=True)
 merchant_product_code = (df['Product code'] + '-' + df[col])
 df['item_group_id'] = df['Product code']
 df['Product code'] = merchant_product_code
 return df

但是有些产品具有空白选项（值为[]），当我应用取消嵌套时，它们会被删除。

在没有选项值的产品上我该如何忽略呢？

取消嵌套之前和之后的PFB屏幕截图，请参阅选项列-

我将我的功能应用于如下所示的数据农场-

full_df=unnest(full_df,'Options','product code')

full_df看起来像下面的屏幕截图-

我已将full_df转换为字典，以将示例粘贴到此处-
