Python Variables

Variable Declaration

Assign values to variables without explicit type declaration. Python uses dynamic typing.

Naming Conventions and Rules

• Variable names must start with a letter or underscore.
• Use lowercase with underscores (snake_case).

Scope of Variables

• Local variables are defined within functions.
• Global variables are defined at the module level.

Best Practices

Choose descriptive variable names and avoid using single letters except for counters or indices.
