File handling is a crucial aspect of programming, especially in web development. It involves reading, writing, and managing files on a server. In this guide, we will explore the basics of file handling and how it works.

Basic Concepts

  • Files: A file is a container for storing information on a storage device.
  • File Handling: It is the process of reading from and writing to files.

Types of Files

  • Text Files: Store plain text data.
  • Binary Files: Store data in a binary format, which can include images, videos, and other non-text data.

File Handling Steps

  1. Open the File: Use the open() function to open a file in read or write mode.
  2. Read/Write: Perform read or write operations on the file.
  3. Close the File: Use the close() function to close the file after operations are complete.

Example

Here is a simple Python script that reads from a file:

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

Image Handling

When dealing with images, you need to consider the file format and how to handle it. For example, if you are working with JPEG images, you might use the PIL library to manipulate them.

from PIL import Image

# Open an image file
img = Image.open('image.jpg')

# Resize the image
img = img.resize((100, 100))

# Save the image
img.save('resized_image.jpg')
