Sort DataFrame by Name Column in Descending Order using Python

Input −

Assume, sample DataFrame is,

  Id Name
0 1 Adam
1 2 Michael
2 3 David
3 4 Jack
4 5 Peter

Output −

After, sorting the elements in descending order as,

  Id Name
4 5 Peter
1 2 Michael
3 4 Jack
2 3 David
0 1 Adam

Solution

To solve this, we will follow the below approaches.

• Define a DataFrame

• Apply DataFrame sort_values method based on Name column and add argument ascending=False to show the data in descending order. It is defined below,

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

Example

Let us see the following implementation to get a better understanding.

import pandas as pd
data = {'Id': [1,2,3,4,5],'Name': ['Adam','Michael','David','Jack','Peter']}
df = pd.DataFrame(data)
print("Before sorting:\n", df)
print("After sorting:\n", df.sort_values(by='Name',ascending=False))

Output

Before sorting:
  Id Name
0 1 Adam
1 2 Michael
2 3 David
3 4 Jack
4 5 Peter
After sorting:
  Id Name
4 5 Peter
1 2 Michael
3 4 Jack
2 3 David
0 1 Adam
