Python File Handling Basics

File handling is an essential aspect of programming that allows developers to store, read, and manipulate data in external files. Python offers built-in functions to perform file operations efficiently.

To begin working with files, use the open() function. This function takes two main arguments: the file name and the mode. The common modes are:

'r': Read (default)

'w': Write (creates a new file or overwrites existing)

'a': Append

'b': Binary mode (used with others like 'rb' or 'wb')

Example:

python

file = open("example.txt", "r")

content = file.read()

print(content)

file.close()

To avoid manual closing of files, Python provides the with statement, which ensures the file is properly closed even if an error occurs:

python

with open("example.txt", "r") as file:

    content = file.read()

    print(content)

For writing:

python

with open("example.txt", "w") as file:

    file.write("Hello, world!")

To append data without erasing the file's contents:

python

with open("example.txt", "a") as file:

    file.write("\nAppended text.")

Reading methods include read(), readline(), and readlines() for full content, single line, or list of lines respectively.

File handling is crucial for tasks like logging, data storage, and configuration management. Python’s simple syntax makes file operations intuitive and powerful, laying the foundation for more advanced file and data processing.
