Jupyter Notebook是一个交互式笔记本,可以用于数据清理和转换、数值模拟、统计建模、数据可视化、机器学习等多个领域的工作。在Jupyter Notebook中,可以使用Python等多种编程语言进行编程,并且可以将代码、文本、图像、音频和视频等多种格式的内容整合到一个文档中。下面是一个简单的Jupyter Notebook采集的例子:
1.首先,安装所需的库,包括requests和beautifulsoup4:
```shell
!pip install requests
!pip install beautifulsoup4
```
2.导入所需的库:
```python
import requests
from bs4 import BeautifulSoup
```
3.使用requests库获取要采集的网页内容:
```python
url = 'https://www.example.com'
response = requests.get(url)
```
4.使用BeautifulSoup库解析网页内容:
```python
soup = BeautifulSoup(response.content, 'html.parser')
```
5.使用BeautifulSoup库提取所需的信息:
```python
title = soup.title.string
print(title)
```
6.将采集到的信息保存到文件中:
```python
with open('example.txt', 'w') as f:
f.write(title)
```
