+====== DataFrame ======
+A DataFrame is like a table, where each row is a Series. A DataFrame identify each row with an index, which defaults to 0..n. Same with the columns.
+===== Indexing =====
+<code python>
+import pandas as pd
+tabledata = {'name'    :['George', 'Frank', 'John'],\
+             'surname' :['Jungle', 'Sinatra', 'Wick',\
+             'mail'    :['jg@jg.com', 'fs@gmail.com', 'wick@burnt.co.uk']}
+df = pd.DataFrame(tabledata)
+</code>
+===== inplace=True =====
+Most operations (?) creates a new dataset unless the property ''inplace=true'' in function calls.
+<code python>
+df.set_index('mail', inplace=True)
