Python, renowned for its simplicity and readability, has enabled developers to create a myriad of useful mini-programs that solve everyday problems. In this article, we’ll explore the code, applications, and benefits of some popular Python mini-programs.
1. File Renamer
A file renamer program is a handy tool that allows users to rename multiple files in a directory based on a specific pattern or criteria. This can be particularly useful when dealing with large numbers of files that require systematic naming.
pythonimport os
def rename_files(directory, pattern, new_name):
for filename in os.listdir(directory):
if pattern in filename:
new_filename = new_name + filename.split(pattern)[1]
os.rename(os.path.join(directory, filename), os.path.join(directory, new_filename))
# Example usage: Rename all files in a directory that contain "_old" to "_new"
rename_files("/path/to/directory", "_old", "_new")
2. Webpage Downloader
A webpage downloader program fetches the content of a webpage and saves it locally in a file. This can be useful for archiving webpages or extracting data for further analysis.
pythonimport requests
def download_webpage(url, filename):
response = requests.get(url)
if response.status_code == 200:
with open(filename, 'w', encoding='utf-8') as file:
file.write(response.text)
# Example usage: Download the content of a webpage and save it as "webpage.html"
download_webpage("https://example.com", "webpage.html")
3. Image Converter
An image converter program allows users to convert images from one format to another. This is useful when dealing with different image formats for various purposes, such as web development or printing.
pythonfrom PIL import Image
def convert_image(input_file, output_file, format):
img = Image.open(input_file)
img.save(output_file, format)
# Example usage: Convert a JPEG image to PNG
convert_image("input.jpg", "output.png", "PNG")
