方法一
在Markdown单元格添加下载链接
<a href="your_file_name.csv"> Download File </a>
方法二
# import the modules we'll need
from IPython.display import HTML
import pandas as pd
import numpy as np
import base64
# function that takes in a dataframe and creates a text link to
# download it (will only work for files < 2MB or so)
def create_download_link(df, title = "Download CSV file", filename = "data.csv"):
csv = df.to_csv()
b64 = base64.b64encode(csv.encode())
payload = b64.decode()
html = '<a download="{filename}" href="data:text/csv;base64,{payload}" target="_blank">{title}</a>'
html = html.format(payload=payload,title=title,filename=filename)
return HTML(html)
# create a random sample dataframe
df = pd.DataFrame(np.random.randn(50, 4), columns=list('ABCD'))
# create a link to download the dataframe
create_download_link(df)
# ↓ ↓ ↓ Yay, download link! ↓ ↓ ↓
