In this tutorial, you'll learn how to sort data in a pandas DataFrame using the pandas sort functions sort_values() and sort_index(). You'll learn how to sort by one or more columns and by index in ascending or descending order.
Pands 提供了两种排序方法,分别是按标签排序和按数值排序。本节讲解 Pandas 的排序操作。 下面创建一组 DataFrame 数据,如下所示: df = pd.DataFrame({'b':[1,2,3,2],'a':[4,3,2,1],'c':[1,3,8,2],'d':[2,0,1,3],})df#输出结果:b a c d01412123302328132123 ...

The ascending=False parameter sorts the DataFrame in descending order. This is useful when you need the highest values first. Sorting by IndexThis example shows how to sort a DataFrame by its index. sort_by_index.py import pandas as pd data = { 'Name': ['Alice', 'Bob', 'Charlie', ...
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…
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': [...
