How to Efficiently Iterate Over Files in a Specific Directory in Python?

Iterating Over Files in a Specified Directory

When working with files inside a particular directory, it becomes necessary to iterate through them efficiently. Here's a step-by-step guide to achieve this task in Python:

Using the os Module:

The os module provides a comprehensive set of functions for interacting with the operating system. To iterate over files within a specific directory, utilize the following code:

import os

# Replace '/path/to/dir/' with your actual directory path
directory = '/path/to/dir/'

# Loop through the files in the directory
for filename in os.listdir(directory):
    # Check if the file has the desired extension
    if filename.endswith('.asm'):
        # Perform desired actions on the file
        pass

Using the pathlib Module:

The pathlib module offers a more object-oriented approach for file handling. Here's how to iterate over files using pathlib:

from pathlib import Path

# Replace '/path/to/dir/' with your actual directory path
directory = '/path/to/dir/'

# Create a Path object for the directory
path = Path(directory)

# Iterate over the files in the directory
for file in path.glob('**/*.asm'):
    # Perform desired actions on the file
    pass
