Handling files in Python
Reading data from a file or writing data to a file is one of the fundamental operations supported by any programming language. Python provides extensive support for handling file operations, which are mostly available in its standard library. In this section, we will discuss core file operations such as opening a file, closing a file, reading from a file, writing to a file, file management with context managers, and opening multiple files with one handle using the Python standard library.
