You can obtain the result of the last expression in a Python REPL with the underscore operator, e.g. in the Python REPL this looks like:
>>> 3 * 3
9
>>> _ + 3
12
This works in the IPython shell too. In addition, the IPython shell allows you to use Out[n]
to get the value of the expression In[n]
. E.g., Out[1]
would give us the number 9 in the example below:
In [1]: 3 * 3
Out[1]: 9
In [2]: Out[1] + 3
Out[2]: 12
In [3]: _ + 3
Out[3]: 15
