Recursively Reading Folder Contents in Python
In Python, you can encounter issues when attempting to recursively traverse directories to read text files. A common problem is code that functions only for a single directory level.
Understanding the os.walk Function
The core of recursive folder traversal in Python lies in the os.walk() function. It iterates over a specified directory and its subdirectories, returning three values: root, subdirs, and files.
Optimizing Folder Traversal
To traverse directories recursively, you should iterate through the list of subdirectories returned by os.walk(). For each subdirectory, you can then call os.walk() recursively to process its contents.
Improved Python Code
The example code can be modified to handle multiple directory levels:
