Python provides builtin functions that explicitly convert between data types. This is commonly known as casting. It is often necessary to cast values when they are used as arguments in a function call. It is generally necessary to cast values whenever a function or other process cannot implicitly convert a given variable to the appropriate datatype. For example when storing RGB color data in a list it is necessary to cast the list to a tuple before using the values in a neopixel object.

tuple(variable) is used to cast lists and other sequential types to the tuple type.
