如何使用熊猫链过滤行？
在本文中，我们将学习如何使用熊猫链接来过滤行。为此，我们首先研究了下面给出的一些以前的术语:
- [Panda data frame: It is a two-dimensional data structure, that is, data is aligned in rows and columns. Panda data framework has three main components, namely data, rows and columns.
- Panda chain: Method chain, which calls methods on an object one by one. Panda has always been a possible programming style. In the past several versions, many methods allowing more links have been introduced.
这里，我们使用 Pandas 中的链接概念来过滤数据帧，并获得与输出相同的行。这很容易通过例子来解释。这里我们使用一个数据框架，它由如下所示的人的一些数据组成:
【Python】
# import package
import pandas as pd
# define data
data = pd.DataFrame(
{'ID': {0: 105, 1: 102, 2: 101, 3: 106, 4: 103, 5: 104, 6: 107},
'Name': {0: 'Ram Kumar', 1: 'Jack Wills', 2: 'Deepanshu Rustagi',
3: 'Thomas James', 4: 'Jenny Advekar', 5: 'Yash Raj',
6: 'Raman Dutt Mishra'},
'Age': {0: 40, 1: 23, 2: 20, 3: 34, 4: 18, 5: 56, 6: 35},
'Country': {0: 'India', 1: 'Uk', 2: 'India', 3: 'Australia',
4: 'Uk', 5: 'India', 6: 'India'}
}
)
