df.sort_values(by='col1', ascending=False)# Python, Pandas
# Sorting dataframe df on the values of a column col1
# Return sorted array without modifying the original one

# Sort the original array permanently

>>> df.sort_values(by=['col1'])

# Basic syntax:
import pandas as pd
df.sort_values(by=['col1'])
# Note, this does not sort in place unless you add inplace=True
# Note, add ascending=False if you want to sort in decreasing order
# Note, to sort by more than one column, add other column names to the
# list like by=['col1', 'col2']
