Introduction Variables in Python are symbolic names used to store data values. They act as containers for data that can be referenced and manipulated throughout the program.
Features of Variables Dynamic Typing: Variables don't require an explicit type declaration; the type is inferred from the value assigned. Case-Sensitivity: Variable names are case-sensitive (myVar and myvar are different). Mutable and Immutable Types: Python supports mutable (e.g., lists, dictionaries) and immutable types (e.g., integers, strings). Naming Rules Variable names must start with a letter (a-z, A-Z) or an underscore (_). The rest of the name can include letters, numbers, and underscores. Variable names cannot be a Python keyword (e.g., if, else, for). Use descriptive names for clarity, such as user_name instead of x.
