原文:https://www.geeksforgeeks.org/how-to-sort-pandas-dataframe/
在本文中，我们将讨论如何对熊猫数据帧进行排序。让我们创建一个数据帧。
例:
蟒 3
# importing pandas library
import pandas as pd
# creating and initializing a nested list
age_list = [['Afghanistan', 1952, 8425333, 'Asia'],
['Australia', 1957, 9712569, 'Oceania'],
['Brazil', 1962, 76039390, 'Americas'],
['China', 1957, 637408000, 'Asia'],
['France', 1957, 44310863, 'Europe'],
['India', 1952, 3.72e+08, 'Asia'],
['United States', 1957, 171984000, 'Americas']]
# creating a pandas dataframe
df = pd.DataFrame(age_list, columns=['Country', 'Year',
'Population', 'Continent'])
df
