IDE Support

The Type Hinting feature of Python is most effectively used in almost all IDEs (Integrated Development Environments) such as PyCharm and VS Code to provide dynamic autocomplete features.

Let us see how VS Code uses the type hints to provide autocomplete suggestions while writing a code. In the example below, a function named as sayhello with name as an argument has been defined. The function returns a string by concatenating Hello to the name parameter by adding a space in between. Additionally, it is required to ensure that the first letter of the name be in upper case.
