How to Learn Python File Input Output
In Python, the `open` function gives you the ability to interact with files. It's used to open files and create a file object, which allows you to read, write, or append content. The `open` function takes two main arguments: the file path and the file mode. The file mode determines the type of operation you want to perform on the file.
File Modes
- 'r' - Read mode: Opens the file for reading. If the file does not exist, an error is raised.
- 'w' - Write mode: Opens the file for writing. If the file does not exist, a new file is created. If the file exists, its contents are truncated.
- 'a' - Append mode: Opens the file for appending. If the file does not exist, a new file is created.
Working with Files
In Python, you can work with files using the `open` function. You can use the `read` method to read the contents of a file, the `write` method to write to a file, and the `close` method to close the file.
To write to a file, you can use the `write` method. For example:
