What is the symbol (which looks similar to an equals sign) called? Example. If you want the function to return a value, you need to define the data type of the return value Just add a return statement at the end of the functions code block and at the first level of indentation. Youll cover the difference between explicit and implicit return values later in this tutorial. Thats because when you run a script, the return values of the functions that you call in the script dont get printed to the screen like they do in an interactive session. Note: The full syntax to define functions and their arguments is beyond the scope of this tutorial. This statement is a fundamental part of any Python function or method. So, to write a predicate that involves one of these operators, youll need to use an explicit if statement or a call to the built-in function bool(). Each step is represented by a temporary variable with a meaningful name. I've managed to eliminate Tuple as an issue, I still get this issue with just str: warning: Returning Any from function declared to return "str". This sounds like a type propagation bug of sorts in mypy since there is no error reported in the type defintion of blabla_call, but only further on does mypy get confused. Upper Upper converts a string to upper case. Watch it together with the written tutorial to deepen your understanding: Using the Python return Statement Effectively. So, good practice recommends writing self-contained functions that take some arguments and return a useful value (or values) without causing any side effect on global variables. * Typing: events.py * Remove unused variable * Fix return Any from return statement Not all elements from the event dict are sure to be something that can be evaluated See e.g. returning any from function declared to return str because {} == other should evaluate to a bool. I have the following directory structure: This works fine when I run in python because the sys.path contains the folder which is one level up of blamodule folder (the root of the project). Then you need to define the functions code block, which will begin one level of indentation to the right. You can use a return statement inside a generator function to indicate that the generator is done. As soon as a function hits a return statement, it terminates without executing any subsequent code. It can also be passed zero or more arguments which may be used in the execution of the body.
