how to sort a dataframe based on a column in python code example

Example 1: sort a dataframe by a column valuepython

>>> df.sort_values(by=['col1'])
    col1 col2 col3
0   A    2    0
1   A    1    1
2   B    9    9
5   C    4    3
4   D    7    2
3   NaN  8    4

Example 2: sort dataframe by column

df.sort_values(by='col1', ascending=False)

Example 3: sorting rows and columns in pandas

df.sort_values(by="ColumnName", axis=0, ascending=False, inplace=False, kind='quicksort')
#axis 0 is rows and axis 1 is columns. For axis 0 by needs to contain column name

Example 4: sort by dataframe

DataFrame.sort_values(self, by, axis=0, ascending=True,
                      inplace=False, kind='quicksort',
                      na_position='last',
                      ignore_index=False)

# Example
df.sort_values(by=['ColToSortBy'])

Example 5: dataframe, sort by columns

final_df = df.sort_values(by=['2'], ascending=False)

Example 6: dataframe sort by column

sorted = df.sort_values('column-to-sort-on', ascending=False)
#or
df.sort_values('name', inplace=True)
