Grasping these concepts is fundamental to Python’s design philosophy. It empowers you to write more efficient and reliable code, as you can predict how your objects will behave when interacting. For example, the knowledge that a dictionary key must be immutable can spare you from potential bugs...
tuple: A tuple is an ordered collection, similar to a list, but their elements cannot be modified once they have been created. Example of an immutable data type (string): Code: str1="Python"new_str1=str1.lower()# Creating a new string with all lowercase charactersprint(str1)# Output:...
Examples of mutable objects in Python include lists, dictionaries, and sets. my_list = [1, 2, 3] my_list[0] = 10 # Modifying the first element print(my_list) # Output: [10, 2, 3] In this example, the list my_list is mutable, so you can modify its elements without creating ...
For example, lists are mutable in Python: int_list = [4, 9] int_list[0] = 1 # int_list is now [1, 9] Python 2.7 And tuples are immutable: int_tuple = (4, 9) int_tuple[0] = 1 # Raises: TypeError: 'tuple' object does not support item assignment Python 2.7 String...
