IPython's output caching system defines several global variables:

• [_] (a single underscore): stores previous output, like Python’s default interpreter.
• [__] (two underscores): next previous.
• [___] (three underscores): next-next previous.

Additionally, after each output x is created, there is a variable _ created with the output as its value. For example:

In [12]: lst = [i for i in range(11)]

In [13]: lst
Out[13]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

In [14]: _13
Out[14]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Also, if you're interested, _i contains the contents of the input cell x:

In [15]: _i12
Out[15]: 'lst = [i for i in range(11)]'
