when should I use lambda code example

Example 1: whats a lambda

x = lambda a, b, c, d, e, f: a + b + c + d + e + f
print(x(31231, 312, 312, 31, 12, 31))

Example 2: why aws lambda is called lambda

In programming, a Lambda expression (or function) is just an anonymous function, i.e., a function with no name.
