70. Search and Filters

1. Introduction​

A file manager should support searching files by name, extension, or size.

2. Searching by Name​

def search_by_name(path, name):
    for root, dirs, files in os.walk(path):
        for file in files:
            if name in file:
                print(os.path.join(root, file))

3. Filtering by Extension​

def search_by_extension(path, extension):
    for root, dirs, files in os.walk(path):
        for file in files:
            if file.endswith(extension):
                print(os.path.join(root, file))

4. Filtering by Size​

def search_by_size(path, min_size):
    for root, dirs, files in os.walk(path):
        for file in files:
            file_path = os.path.join(root, file)
            if os.path.getsize(file_path) >= min_size:
                print(file_path)

5. Integrating with CLI​

if args.command == "search":
    search_by_name(".", args.path)

6. Next Steps​

✅ We can now search and filter files.
Next: Error handling to make the program more robust.
