Question

I am running this cell in IPython Notebook:

# salaries and teams are Pandas dataframe
salaries.head()
teams.head()

The result is that I am

Answer 1

Enumerating all the solutions:

• sys.displayhook(value), which IPython/jupyter hooks into. Note this behaves slightly differently from calling display, as it includes the Out[n] text. This works fine in regular python too!

• display(value), as in this answer

• get_ipython().ast_node_interactivity = 'all'. This is similar to but better than the approach taken by this answer.

Comparing these in an interactive session:

In [1]: import sys

In [2]: display(1)          # appears without Out
   ...: sys.displayhook(2)  # appears with Out
   ...: 3                   # missing
   ...: 4                   # appears with Out
1
Out[2]: 2
Out[2]: 4

In [3]: get_ipython().ast_node_interactivity = 'all'

In [2]: display(1)          # appears without Out
   ...: sys.displayhook(2)  # appears with Out
   ...: 3                   # appears with Out (different to above)
   ...: 4                   # appears with Out
1
Out[4]: 2
Out[4]: 3
Out[4]: 4

Note that the behavior in Jupyter is exactly the same as it is in ipython.
