https://codeyarns.com/2010/01/28/python-checking-type-of-variable/ isinstance()seems to be the preferred way to check thetypeof a Python variable. It checks if the variable (object) is an instance of the class object being checked against. # Variables of different types i = 1 f = 0.1...
Python is a dynamically typed language. This means that the Python interpreter does type checking only as code runs, and that the type of a variable is allowed to change over its lifetime. The following dummy examples demonstrate that Python has dynamic typing:...

Alternately, you can use a custom environment variable that's defined on each platform to contain the full path to the Python interpreter to use, so that no other folder paths are needed. If you need to pass arguments to the Python interpreter, you can use thepythonArgsproperty. ...

It isn't guaranteed that the state of your app will be preserved for future executions. However, the Azure Functions runtime often reuses the same process for multiple executions of the same app. To cache the results of an expensive computation, declare it as a global variable....
