Study Notes

Statements in Python

A statement in Python is an instruction that the interpreter executes.
The most commonly used type of statement in Python is the assignment statement.

Assignment Statement

An assignment statement assigns a value to a variable.

Extending Statements over Multiple Lines

A Python statement can be extended over multiple lines using parentheses, brackets, or the line continuation character ().

Statements with No Result

A statement that does not produce a result in Python is called a "procedure" or "command".

Functions in Python

Breaking a program into smaller modular chunks using functions makes it easier to manage and maintain.
Functions allow for code reuse and reduce code duplication.

Built-in Functions

Built-in functions include functions like len(), type(), and abs() in Python.

Documenting Functions

The optional documentation string of a function should be placed immediately after the function definition, inside a triple-quoted string.

Function Arguments

Arguments are specified when passing information into a function by placing them in parentheses after the function name.

The 'return' Statement

The role of the 'return' statement in a Python function is to send a value back to the caller.

Benefits of Modular Programming

The primary benefit of breaking a program into smaller modular chunks using functions is that it makes the code more organized, readable, and maintainable.

Function Documentation

The optional documentation string of a function in Python should be placed immediately after the function definition, inside a triple-quoted string.

The 'return' Statement

The role of the 'return' statement in a Python function is to send a value back to the caller.

Built-in Functions

Built-in functions in Python include functions like len(), type(), and abs().

Extending Statements over Multiple Lines

A Python statement can be extended over multiple lines using parentheses, brackets, or the line continuation character ().
