Which of the following statements correctly defines a function?

Question

BlackTom AI · Accepted Answer

Starting with a broad look at what counts as a function definition in most programming languages: a definition typically begins with a keyword that declares a function, followed by the name, parameters list, and a terminating symbol like a colon in Python.
Option 1: 'functionName(parameterName1, parameterName2)' looks like a function call or a signature inside code but it lacks the defining keyword (such as 'def' in Python), so it does not constitute a function definition.
Option 2: 'functionName(parameterName1, parameterName2) :' also resembles a call or a parameter list, and even with a trailing colon, it still lacks the essential 'def' keyword required to define a function in Python; thus it is not a valid function definition.
Option 3: 'def functionName(parameterName1, parameterName2)' includes the 'def' keyword but is missing the crucial colon that ends the function header in Python, so this is not a complete function definition.
Option 4: 'def functionName(parameterName1, parameterName2) :' includes the 'def' keyword, the function name, the parameters, and what appears to be the header colon (note the space before the colon, which is allowed in Python). This matches the proper structure of a function definition in Python, making it the correct choice.
To summarize the common rules: a proper Python function definition starts with 'def', includes the name and parameter list, and ends the header with a colon. Anything missing one of these elements is not a valid definition. Therefore, Option 4 best satisfies the correct definition criteria.
