Assignments

Assigning a value to a variable is done using the = operator.

The variable takes on the type of the assigned value dynamically.

Pythonx = 10  # 'x' is assigned the value 10
y = "Hello"  # 'y' is assigned the string "Hello"
        

Multiple Assignments

You can assign values to multiple variables in a single line.

Pythona, b, c = 1, 2, 3  # 'a' is 1, 'b' is 2, 'c' is 3

Variable 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

Choose meaningful and descriptive names to enhance code readability

Python_my_var = 42  # Variable name starts with an underscore

Dynamic Typing

Python is dynamically typed, meaning you don't explicitly declare the data type of a variable.

The interpreter dynamically determines the type based on the assigned value.

Pythondynamic_var = 3.14  # 'dynamic_var' is dynamically assigned the float type

Variable Reassignment

Variables can be reassigned to new values, even of a different type.

Pythoncount = 5
count = "Hello"  # Reassigning 'count' to a new value with new type (string)
