Cannot Add Data Frames to List

Asked 5 months ago, Updated 5 months ago, 14 views

Python 3.7.6.
I'm trying to add data frames to the list, but it doesn't work because it's judged to be str type.
The results are as follows:
files is a list that contains the file path to be read by the func function.

for i in files:

TypeError: list indications must be integrators or slices, not str

Looking for str, it looks like a data frame.

Out [10]—pandas.core.frame.DataFrame

Is it impossible to append the data frame to the list?
I would appreciate it if you could reply to me if you know more.

Thank you for your cooperation.

For example, the dataframe name is name_df.
First, retrieve the dataframe column.


Then use the columns to store dataaframe elements in the array.

 lis=[ ]
for w, i in enumerate (files):

Can I do what I want with this?
I don't really understand what I want to do, so it may be a vague answer.
Try it
