* 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 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=":")
