This article introduces the knowledge of "how to use Python to read files in a folder in order". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

We sometimes read all the files in a folder. However, the file names returned by os.listdir () are not necessarily sequential, which requires us to sort the list of file names returned:

At this point, we want to sort it using the numbers after Epoch, as follows:

Def file_name (path): train_loss_list = [] val_loss_list = [] loss_file_name = [] files = os.listdir (path) # uses listdir to read all files for i in files: loss_file_name.append (i.strip ("Epoch")) loss_file_name.sort (key=lambda x: int (x [: x.find ("-")])) # Sort print (loss_file_name) by the preceding numeric character

The filenames read in this way are arranged in order, and then we can use the loss data of train and val to be read sequentially for drawing.

Import ospath= "/ home/test/" # folder to be read path_list=os.listdir (path) path_list.sort () # sort the paths read for filename in path_list: print (os.path.join (path,filename)) "how to use Python to read files in a folder in order" is introduced here, thank you for reading.
