Pandas - 3. Italian poets challenge

Download exercises

For a digital humanities project you need to display poets by filtering a csv table according to various criteria. This challenge will be only about querying with pandas, which is something you might find convenient to do during exams for quickly understanding datasets content (using pandas will always be optional, you will never be asked to perform complex modifications with it)

You are given a dataset taken from Wikidata, a project by the Wikimedia foundation which aims to store only machine-readable data, like numbers, strings, and so on interlinked with many references. Each entity in Wikidata has an identifier, for example Dante Alighieri is the entity Q1067 and Florence is Q2044

Wikidata can be queried using the SPARQL language: the data was obtained with this query and downloaded in CSV format (among the many which can be chosen). Even if not necessary for the purposes of the exercise, you are invited to play a bit with the interface, like trying different visualizations (i.e. try select map in the middle-left corner) - or see other examples

What to do

  1. If you haven’t already, install Pandas:

    Anaconda:

    conda install pandas

    Without Anaconda (--user installs in your home):

    python3 -m pip install --user pandas

  2. unzip exercises in a folder, you should get something like this:

pandas
    pandas1-sol.ipynb
    pandas1.ipynb
    pandas2-sol.ipynb
    pandas2.ipynb
    pandas3-chal.ipynb
    jupman.py

WARNING 1: to correctly visualize the notebook, it MUST be in an unzipped folder !

  1. open Jupyter Notebook from that folder. Two things should open, first a console and then browser.

  2. The browser should show a file list: navigate the list and open the notebook pandas3-chal.ipynb

WARNING 2: DO NOT use the Upload button in Jupyter, instead navigate in Jupyter browser to the unzipped folder !

  1. Go on reading that notebook, and follow instuctions inside.

Shortcut keys:

  • to execute Python code inside a Jupyter cell, press Control + Enter

  • to execute Python code inside a Jupyter cell AND select next cell, press Shift + Enter

  • to execute Python code inside a Jupyter cell AND a create a new cell aftwerwards, press Alt + Enter

  • If the notebooks look stuck, try to select Kernel -> Restart

Load the dataset

[1]:
import pandas as pd   # we import pandas and for ease we rename it to 'pd'
import numpy as np    # we import numpy and for ease we rename it to 'np'

df = pd.read_csv('italian-poets.csv', encoding='UTF-8')
