Statement
A statement is a syntactic program construct that performs an action, declaration, or control operation without necessarily producing an expression value.
Get Programming: Learn to code with Python
A complete line or instruction of Python code that the interpreter executes as part of a program.
- How it is used
- Identifies the lines a Python program executes and distinguishes straight-line execution from choosing lines according to user input.
- How deep it goes
- Defines a statement as a line of code and contrasts it with an expression through short examples, without detailing interpreter internals.
- Examples
- Uses arithmetic, assignment, and printing lines for classification, plus console trials that contrast inspected results with printed output.
- What you can do after
- Practice/perform classification of lines as statements or expressions and recognize when program decisions change which statements run.

F# in Action: A Revised Edition of Get Programming with F#
A statement is a program construct that performs an action or controls execution without necessarily evaluating to a usable value.
- How it is used
- Uses statements to compose imperative code through execution control, state changes, and external effects.
- How deep it goes
- Defines statements by their missing return value and side effects, then examines branching bugs before contrasting expressions.
- Examples
- Uses an age-description conditional, a flow diagram, and an exercise distinguishing statements from expressions.
- What you can do after
- Evaluate code by distinguishing value-producing expressions from effectful statements and spotting incomplete or unsafe branch assignments.

The Quick Python Book, Fourth Edition
A statement is a syntactic unit representing an executable instruction in a programming language.
- How it is used
- Organizes executable Python instructions into blocks, control-flow constructs, and scripts.
- How deep it goes
- Defines statements, blocks, indentation, compound clauses, and errors, but stops short of implementation internals.
- Examples
- Uses assignments, function calls, print, pass, del, conditional branches, nested blocks, and a small file script.
- What you can do after
- Build basic Python scripts and diagnose indentation errors in simple and compound statements.
