-This just contains learner python programs.
+This contains executable program to generate Fibonacci series using recursive approacch .
+
+The Fibonacci Sequence is the series of numbers:
+
+0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
+
+The next number is found by adding up the two numbers before it:
+
+-> the 2 is found by adding the two numbers before it (1+1),
+-> the 3 is found by adding the two numbers before it (1+2),
+-> the 5 is (2+3),
+.... and so on!
