+A lambda function is a small anonymous function.
+
+A lambda function can take any number of arguments, but can only have one expression.
+
+Syntax:
+
+*lambda arguments : expression*
+
+The expression is executed and the result is returned:
+
+#+begin_src python :results output
+
+  # Add 10 to argument a, and return the result:
+  x = lambda a : a + 10
+  print(x(5))
+
+  # Multiply argument a with argument b and return the result:
+  y = lambda a, b : a * b
+  print(y(5, 6)) 
+
+  # Summarize argument a, b, and c and return the result:
+  z = lambda a, b, c : a + b + c
+  print(z(5, 6, 2))
