Data Structures & Python Syntax Rules

Definition of Syntax Rules:

The strict set of grammatical rules governing how a programming language must be structured so the compiler or interpreter can understand

question

What are the strict rules regarding Python keywords, variable names, and code blocks?

The 3 Rules to Remember

• Case Sensitivity: Built-in commands are entirely lowercase. Writing Def or Input instead of def or input creates an immediate breakdown.

• Variable Identifiers: Variable names must be single continuous strings. Blank spaces are illegal (e.g., Total mileage must be written as total_mileage).

• Indentation Blocks: Python does not use curly brackets {} to enclose blocks of code. It relies entirely on whitespace indentation (usually 4 spaces) to show that a line of code is nested inside a function, loop, or conditional statement.
