Python: Check if Variable is a List
Introduction
Python is a dynamically typed language, and the variable data types are inferred without explicit intervention by the developer.
If we had code that needed a list but lacked type hints, which are optional, how can we avoid errors if the variable used is not a list?
In this tutorial, we’ll take a look at how to check if a variable is a list in Python, using the type() and isinstance() functions, as well as the is operator:
Developers usually use type() and is, though, these can be limited in certain contexts, in which case, it’s better to use the isinstance() function.
Check if Variable is a List with type()
The built-in type() function can be used to return the data type of an object. Let’s create a Dictionary, Tuple and List and use
