10 paź 2024 · Even though Python doesn’t require you to specify types (it’s dynamically typed), the -> notation can be a helpful way to show what kind of data your functions are expected to give back. In this guide, we’ll break down exactly what the -> symbol means, why and when to use it, and how it can improve your Python coding. Ready?

The main motive is to provide a documented code and a standard way to associate a data type hint with functioning arguments and returning value.
Python Operators enable us to manipulate and combine values, making our code more dynamic and functional. By understanding how operators work in Python, we can effectively perform tasks such as arithmetic calculations, logical comparisons, and string manipulations.
