In Python, function names starting with an underscore (_) have a special significance. These names are often referred to as "private" or "internal" names, and they are meant to indicate that the function is intended for internal use within the module or class, rather than being part of the public API. While using such names doesn't enforce privacy in the way that some other languages do, it serves as a convention to signal to other developers that the function is not intended for general use.
Let's go through the concept of using underscore-prefixed function names with some code examples.
Private functions are those intended for internal use within a module. These functions are not meant to be accessed directly from outside the module.
Similar to modules, classes can have internal functions that are not intended for external use.
In Python, a double underscore (__) prefix causes the interpreter to "mangle" the name of the method or attribute. This is often used to make the name more unique and avoid accidental name clashes in large codebases.
While using underscore-prefixed names provides a level of indication for developers, it's important to note that Python does not enforce privacy. Developers should adhere to naming conventions and be aware of the intended use of functions and variables in their codebase. Use underscore-prefixed names responsibly to communicate the intended scope of your code.
