A lambda function in Python is an anonymous, single-line function defined with the keyword ‘lambda’, not ‘def’. A return statement isn’t explicitly used within a lambda function. Instead, the expression following the colon is implicitly returned. For instance, to create a lambda function that adds two numbers:
add = lambda x, y: x + y
. Here, the sum of x and y is automatically returned when the function is called. To use this function, you would write something like
result = add(5, 3)
, which assigns the value 8 to result.
