What's the Difference Between Expressions and Statements in Python?

The Distinction between Expressions and Statements in Python

Expressions and statements are fundamental elements in Python programming, each serving a distinct purpose.

Expressions

In Python, expressions are constructs that can be evaluated to produce a value. They exclusively comprise identifiers, literals, and operators, such as arithmetic and boolean operators, as well as function calls and subscription operators like [].

Statements

Statements, on the other hand, represent units of Python code. They can have varying forms but all serve the purpose of executing actions. Statements can include expressions, but they may also include keywords, such as "if" and "return", and other structures like assignments and function definitions.

Examples

Expressions:

• 5 3
• [i for i in range(10)]

Statements:

• print(42)
• if x: do_y()
• for i in range(10): pass
• a = b
