Recipe Objective

Have you ever tried to sort a dataframe according to ascending or decending order with respect to features.

So this is the recipe on we can sort rows within a Pandas DataFrame.

Step 1 - Import the library

import pandas as pd

We have imported pandas which is needed.

Step 2 - Setting up the Data

We have created a dataset by making a dictionary with features and passing it through the dataframe function. raw_data = {"first_name": ["Sheldon", "Raj", "Leonard", "Howard", "Amy"], "last_name": ["Copper", "Koothrappali", "Hofstadter", "Wolowitz", "Fowler"], "age": [42, 38, 36, 41, 35], "Comedy_Score": [9, 7, 8, 8, 5], "Rating_Score": [25, 25, 49, 62, 70]} df = pd.DataFrame(raw_data, columns = ["first_name", "last_name", "age", "Comedy_Score", "Rating_Score"]) print(df)

Step 3 - Sorting the dataset

For better understanding we are first sorting the dataset with respect to age and in decending order. Then again with respect to age in ascending order. Finally with respect to both first age then Comedy_Score. print(df.sort_values(by="age", ascending=0)) print(df.sort_values(by="age", ascending=1)) print(df.sort_values(by=["age", "Comedy_Score"])) So the output comes as

  first_name     last_name  age  Comedy_Score  Rating_Score
0    Sheldon        Copper   42             9            25
1        Raj  Koothrappali   38             7            25
2    Leonard    Hofstadter   36             8            49
3     Howard      Wolowitz   41             8            62
4        Amy        Fowler   35             5            70

  first_name     last_name  age  Comedy_Score  Rating_Score
0    Sheldon        Copper   42             9            25
3     Howard      Wolowitz   41             8            62
1        Raj  Koothrappali   38             7            25
2    Leonard    Hofstadter   36             8            49
4        Amy        Fowler   35             5            70

  first_name     last_name  age  Comedy_Score  Rating_Score
4        Amy        Fowler   35             5            70
2    Leonard    Hofstadter   36             8            49
1        Raj  Koothrappali   38             7            25
3     Howard      Wolowitz   41             8            62
0    Sheldon        Copper   42             9            25

  first_name     last_name  age  Comedy_Score  Rating_Score
4        Amy        Fowler   35             5            70
2    Leonard    Hofstadter   36             8            49
1        Raj  Koothrappali   38             7            25
3     Howard      Wolowitz   41             8            62
0    Sheldon        Copper   42             9            25
