Mutable And iMmutable
in Python
Lists, dictionaries, and sets can be modified after creation.
Add, remove, or change elements – they're flexible!
The Mutables: Masters of Transformation
Python
my_list = [1, 2, 3]
my_list.append(4) # Add an element
print(my_list) # Output: [1, 2, 3, 4]

Numbers, strings, and tuples can't be changed directly.
If you need to modify? Create a new one based on the old.
The Immutables

Python
name = "Alice"
# Trying to change a character directly results in an error
# name[0] = "B" # This will cause an error
Immutable Example: The String Stays the Same

Use mutables when data needs to change. Immutables are great for security and clear function logic.
When to Choose Mutable or Immutable
Understanding these concepts is essential for writing Python programs. Choose wisely for powerful code!
