File handling

Reading and writing a csv or txt file can be achieved using the same code, just change the file extension.

Note: Anything read from a file is a string. If the value represents another data type then it must be cast to that data type.

Example data

The data used in the examples can be represented in a table:

Name	Age	Height
Alan	24	1.78
Beth	23	1.63
Carl	22	1.89
Dina	21	1.59

It can also be represented as a text file, e.g. people.csv or people.txt.

Alan,24,1.78
Beth,23,1.63
Carl,22,1.89
Dina,21,1.59
