+* Objectives
+  At the end of this tutorial, you will be able to,
+  - Read data from files with a single column of data.
+  - Read data from files with multiple columns seperated by
+    spaces and other delimiters.
 * Question 1
-  Read the file ~pendulum_semicolon.txt~ which contains the same data
-  as ~pendulum.txt~, but the columns are separated by semi-colons
-  instead of spaces. Use the IPython help to see how to do this.
-* Solution 1
-  #+begin_src python
-    In []: L, T = loadtxt('/home/fossee/pendulum_semicolon.txt', unpack=True, delimiter=';')
-    
-    In []: print L
-    
-    In []: print T
-  #+end_src
+  Read the file  ~pendulum\_semicolon.txt~  which contains the same data
+  as  ~pendulum.txt~ , but the columns are seperated by semi-colons instead
+  of spaces.Use the IPython help to see how to do this.
 * Summary
-  + Read data from files, containing a single column of data using the
+  In this tutorial,we have learnt to-
+  - Read data from files, containing a single column of data using the
     ~loadtxt~ command.
-  + Read multiple columns of data, separated by spaces or other
-    delimiters.
-* Thank you!
+  - Read multiple columns of data, separated by spaces or other
+    delimiters by adding additional arguments to the ~loadtxt~ command.
+* Evaluation
+  1. ``loadtxt`` can read data only from a file with one column only.
+     True or False?
+
+  2. Given a file ``data.txt`` with three columns of data separated by
+     spaces, read it into 3 separate simple sequences. 
+
+  3. Given a file ``data.txt`` with three columns of data separated by
+     ":", read it into 3 separate simple sequences.
+  
+* Solutions
+  1. False
+
+  2. x = loadtxt("data.txt", unpack=True)
+
+  3. x = loadtxt("data.txt", unpack=True, delimiter=":")
