Iterating over columns

...

Iterating over rows

To iterate over rows, you have several choices: .iteritems(), .iterrows(), .itertuples().

Try to figure out what the difference between these three choices are! What does each of them actually return? (They are all different!)

for (key, value) in df.iteritems():
    print(key, value)

for (row_index, row) in df.iterrows():
    print(row_index, row)

for row in df.itertuples():
    print(row)
