• How to Create a Variable:

my_age = 12        # Stores the number 12

• Rules for Naming:
  • Must start with a letter or underscore.
  • Can contain letters, numbers, and underscores.
  • Case-sensitive (age and Age are different).

• Data Types: Variables automatically determine their data type based on the value assigned:
  • Numbers (int, float)
  • Text (string)
  • True/False (boolean)
  • Lists, dictionaries, etc.
