* 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.
* Exercise 1
  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
  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 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=":")
