Recursive sub folder search and return files in a list python

阅读更多关于 Recursive sub folder search and return files in a list python

I am working on a script to recursively go through subfolders in a mainfolder and build a list off a certain file type. I am having an issue with the script. Its currently set as follows for root, subFolder, files in os.walk(PATH): for item in files: if item.endswith(".txt") : fileNamePath = str(os.path.join(root,subFolder,item)) the problem is that the subFolder variable is pulling in a list of subfolders rather than the folder that the ITEM file is located. I was thinking of running a for loop for the subfolder before and join the first part of the path but I figured Id double check to see

Non-recursive os.walk()

问题 I'm looking for a way to do a non-recursive os.walk() walk, just like os.listdir() works. But I need to return in the same way the os.walk() returns. Any idea? Thank you in advance. 回答1: next(os.walk(...)) 回答2: Add a break after the filenames for loop: for root, dirs, filenames in os.walk(workdir): for fileName in filenames: print (fileName) break #prevent descending into subfolders This works because (by default) os.walk first lists the files in the requested folder and then goes into
