Explain debug control buttons and how to walk through a directory tree
A. Debug Control Buttons in Python IDEs (like VS Code or PyCharm)
These buttons help control how your code runs during debugging:
| Button | Function |
|---|---|
| Continue | Runs the program until the next breakpoint or the end. |
| Step Over | Executes the current line but skips inside any function calls. |
| Step Into | Steps into the function call and lets you debug it line by line. |
| Step Out | Finishes the current function and returns to the calling point. |
| Restart | Restarts the entire program from the beginning. |
These tools help find bugs by running the code step-by-step.
B. Walking Through a Directory Tree
Python’s os.walk() function lets you visit every folder and file under a directory.
Example:
import os
for foldername, subfolders, filenames in os.walk('my_directory'):
print('Current folder:', foldername)
print('Subfolders:', subfolders)
print('Files:', filenames)
print()
foldername: Current folder path.subfolders: List of subfolders inside it.filenames: List of files inside the folder.
Use Case Example Output:
Current folder: my_directory Subfolders: ['images', 'docs'] Files: ['file1.txt', 'file2.py']
This is helpful for:
- Finding specific files.
- Performing bulk operations (e.g., renaming, deleting).
- Creating folder summaries.
