Summary. Well done! You’ve made it to the end of this course. You now know how to use two core methods at the pandas library: .sort_values() and .sort_index(). With this knowledge, you can perform basic data analysis with a DataFrame. While there…
Given a Pandas DataFrame, we have to update index after sorting. Submitted byPranit Sharma, on June 28, 2022 Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mainly deal with a dataset in the form of DataFrame.Da...
Sorting in Descending OrderThis example demonstrates how to sort data in descending order. sort_descending.py import pandas as pd data = { 'Name': ['Alice', 'Bob', 'Charlie', 'David'], 'Age': [25, 30, 35, 20], 'Salary': [50000, 60000, 70000, 40000] } df = pd.DataFrame(...
Write a Pandas program to merge DataFrames with custom sorting. This exercise demonstrates how to merge two DataFrames and sort the result by a specific column.Sample Solution :Code :import pandas as pd # Create two sample DataFrames df1 = pd.DataFrame({ 'ID': [1, 2, 3], 'Name': [...
