Examples of immutable data types in Python include: int: Integer data type represents whole numbers, and once created, their value cannot be changed. float: Floating-point data type represents real numbers and is immutable. str: String data type represents a sequence of characters, and you canno...
tuples, and numbers, are immutable. Altering them inside a function/method will create a new instance and the original instance outside the function/method is not changed. Other objects, like lists and dictionaries are mutable, which means you can change the object in-place. Therefore, altering...

Tuples in Python are immutable, meaning you cannot mutate them; you cannot change them. Except you can change the value of a tuple... sort of. Tuples can contain mutable objects We have a dictionary here, called data: >>> data = {"name": "Trey", "color": "purple"} And we ...
Notice that ‘L’ was not added to the end of the output above. Dictionaries are unordered collections of key-value pairs. restrictions: A key of a dictionary cannot be or contain a mutable value. There can be at most one value for a given key. ...
is reasonable for many provenance applications but may produce verbose results once we move towards fine-grained provenance due to the possibility of multiple binds (i.e., variables, elements of data structures) referring to the same mutable data objects (e.g., lists or dictionaries in Python)...
