    32 * Outline

    33   + Read data from files with a single column of data

    34   + Read data from files with multiple columns

    35 * Question 1

    36   Read the file ~pendulum_semicolon.txt~ which contains the same data

    37   as ~pendulum.txt~, but the columns are separated by semi-colons

    38   instead of spaces. Use the IPython help to see how to do this.

    39 * Solution 1

    40   #+begin_src python

    41     In []: L, T = loadtxt('/home/fossee/pendulum_semicolon.txt', unpack=True, delimiter=';')

    42     

    43     In []: print L

    44     

    45     In []: print T

    46   #+end_src

    47 * Summary

    48   + Read data from files, containing a single column of data using the

    49     ~loadtxt~ command.

    50   + Read multiple columns of data, separated by spaces or other

    51     delimiters.

    52 * Thank you!
