Question

我创建了一个数据框列表，我必须为其提取相同数据框的名称以使用它来命名新生成的数据框。我想从“ for-loop”中命名新生成的数据框，类似于（表示）它们各自的数据框。

list_containing_dataframes = [Furnishings, Labels, Accessories, Binders, Supplies, Phones, Tables]

for i in list_containing_dataframes:
  # some operations done on 'i' to generate new dataframes !
  # let's save the newly generated dataframes! 
  newly_generated_dataframes.to_csv(str(i)+'_forecast' , index = False, encoding = 'utf-8')

#  .to_csv() function is being used to save the dataframes in csv format in google colab!
# Expected - The name of newly generated dataframes to be 'name of dataframe #operated on'+'forecast'.
# example- Tables_forecast, where df_Tables is the name of Dataframe operated on!
# Error - str(i) in '.to_csv()' function prints the name along with the index column which becomes so long that it throws error 'name too long!'
# I just want the name of the dataframe along with string '_forecast' attached to it!

为什么不将datafarmes放入字典中，并使用键来命名csv：

dict_containing_dataframes = {'Furnishings': Furnishings, 'Labels': Labels, 'Accessories': Accessories, 'Binders': Binders, 'Supplies': Supplies, 'Phones': Phones, 'Tables': Tables}

for key, one_dataframe in dict_containing_dataframes.items()
    newly_generated_dataframes.to_csv(key+'_forecast' , index = False, encoding = 'utf-8')

如何从for循环中的数据帧列表中提取/提取数据帧的名称以在同一for循环中使用它？
