Examples
>>> df = pd.DataFrame({'animal': ['alligator', 'bee', 'falcon', 'lion', ... 'monkey', 'parrot', 'shark', 'whale', 'zebra']}) >>> df animal 0 alligator 1 bee 2 falcon 3 lion 4 monkey 5 parrot 6 shark 7 whale 8 zebra
Viewing the first 5 lines
>>> df.head() animal 0 alligator 1 bee 2 falcon 3 lion 4 monkey
Viewing the first n lines (three in this case)
>>> df.head(3) animal 0 alligator 1 bee 2 falcon
For negative values of n
>>> df.head(-3) animal 0 alligator 1 bee 2 falcon 3 lion 4 monkey 5 parrot
