+#  Lambda functions are called anonymous functions because they don't have a name,
+#  and they are not defined with the def keyword. Instead,
+#  they are defined using the lambda keyword followed by a list of arguments,
+#  a colon, and an expression that is evaluated and returned as the result of the function.
+
+# Example 1
+# this is a simplest example of a lambda function that inputs an integer and returns its square
+unknownSquarer_func = lambda x: x*2
+
+print(unknownSquarer_func(2))  # --> 4
+
+
+# Example 2
+
+# iterable list
+
+numList = [1,2,3,4,5]
+
+# this lambda function is the function that will be applied to each item in iterable using map keyword
+
+squaredNumbers = map(lambda x:x*2,numList)
+
+print(list(squaredNumbers))
