Certified Associate in Python Programming (PCAP-31-03) — Question 38

What is true about lambda functions? (Choose two.)

Answer options

• A. they are called anonymous functions
• B. they cannot return the None value as a result
• C. they must contain the return keyword
• D. they must have a non-zero number of parameters

Correct answer: A, D

Explanation

Option A is correct because lambda functions are indeed referred to as anonymous functions due to their lack of a named identifier. Option D is also correct as lambda functions must take at least one parameter; the other options are incorrect because lambda functions can return None, do not require a return keyword, and can have zero or more parameters.
