Boston Python workshop 2/Friday tutorial: Difference between revisions

There's a helpful function (more on what a function is in a second) called <code>type</code> that tells you what kind of thing -- what <b>data type</b> -- Python thinks something is. We can check for ourselves that Python considers '1' and '1.0' to be different data types:

* Functions are a lot like functions in math class. You provide input to a function, and it possibly produces output. The '<code>type'</code> function takes data as an input, and produces what type of data the data is (e.g. an integer or a float) as output.

Stop here and try hitting the Up arrow on your keyboard. The Python <b>interpreter</b> saves a history of what you've entered, so you can arrow up to old commands and hit Return to re-run them!
