sinfo() # Writes dependencies to `sinfo-requirements.txt` by default # # Pandas display options # # There are many ways to get sample data to work with, including `sklearn.datasets`, `statsmodels.datasets` (includes all R datasets), and `quilt` (a package manager for data sets). More [details can be found in this SO answer](https://stackoverflow.com/a/29956221/2166823). For small examples, I tend to use `seaborn.load_dataset()` since I will import seaborn anyways (note these datasets are just there for the `seaborn` documentation and may change without notice). # In[2]: iris = sns.load_dataset('iris') iris.head() # It is a little bit annoying to type `head()` every time I want to look at a dataframe. `pandas` has options to control the displayed data frame output and even a nice search interface to find them. # In[3]: pd.describe_option('row') # In[4]: pd.set_option('display.max_rows', 9) # We can see that this has changed the current value. # In[5]: pd.describe_option('max_row') # And if we type the `iris` now, we wont get flooded with 60 rows. # In[6]:
