Question

您好我获得了一系列销售数据，并被要求根据当前价值或我经常出售的销售数据预测可以进行多少类似的销售。

我打算使用excel和tableau但是想利用python的强大功能完成任务。

你能帮忙吗？

Answer 1

这可能会有所帮助

from xml.etree.ElementTree import ElementTree
from collections import defaultdict

mydoc=ElementTree(file='Stack.html')
value=0
sales=[]
values=[]

for e in mydoc.findall('.//tr'):
    sales.append(e.find('.//td[1]').text)
    values.append(e.find('.//td[2]').text)
mylist=list(zip(values,sales))
mydict=defaultdict(list)
for values,sales in mylist:
    mydict[values].append(sales)
print (mydict.items())

您可以使用itervalue（首选）获取您可能使用的网站价值BeutifulSoup或NLTK
