		"person": "Clara",
		"sales": 3000,
		"lastName": "Brown"
	},
	{
		"person": "Greg",
		"sales": 3000,
		"lastName": "Genee"
	}
])

# Sort by single column
sortedDf = df.sort_values(by='sales')
print(sortedDf.head())

# Sort by multiple columns
sortedDf2 = df.sort_values(by=['sales', 'pearson'])
print(sortedDf2.head())
