## Maximizing Efficiency in Python by Ignoring Return Values
In Python, functions inherently return a value. If a function doesn't explicitly use a `return` statement, it implicitly returns `None`. While this is a core feature of the language, there are situations where you want to call a function solely for its side effects (e.g., modifying a mutable object, writing to a file, performing I/O) and you don't need or care about the returned value.
This tutorial explores techniques for maximizing efficiency when dealing with functions whose return values are irrelevant, specifically focusing on strategies to prevent unnecessary work related to the return value and how to indicate to the Python interpreter and other developers that the return value is being intentionally ignored.
**Why Ignore Return Values Efficiently?**
While seemingly trivial, inefficiently handling return values can have subtle performance impacts, especially in performance-critical code or tight loops. Here's why you should care:
1. **Garbage Collection Overhead:** If you don't assign the return value to a variable, Python's garbage collector (GC) still needs to clean up the temporary object created as the function's return. While GC is generally efficient, frequent object creation and disposal can add overhead.
2. **Unnecessary Copies:** In some cases, returning large objects can involve copying data, even if the returned value is immediately discarded. Avoiding these copies, especially with immutable objects, can significantly improve performance.
3. **Readability and Maintainability:** Explicitly indicating that you're ignoring a return value enhances code clarity. It tells other developers (and your future self) that the function is being called for its side effects, not for its returned data.
**Strategies for Ignoring Return Values Efficiently**
Here are several strategies, ranked from simplest to potentially most impactful, with considerations for their pros and cons:
