如何使用 xlwt 将 python 数据导出到 excel？

Question

这是我的拼图：

from bs4 import BeautifulSoup
import requests

url = 'http://www.baseballpress.com/lineups'

soup = BeautifulSoup(requests.get(url).text, 'html.parser')

for names in soup.find_all(class_="players"):
    print(names.text)

我想使用 xlwt 将我的内容导入 excel。我使用下面的代码来查看是否可以使用 python:

制作 excel sheet

import xlwt  

wb = xlwt.Workbook()  
ws = wb.add_sheet("Batters")  
ws.write(0,0,"coding isn't easy")  
wb.save("myfirst_xlwt")

上面的代码有效。我现在想把它应用到我原来的刮擦上。如何合并这两个代码？

我是新手，如有任何帮助，我们将不胜感激。谢谢你的时间！ =)

Answer 1

我试图运行你的代码，但它没有找到任何 class of example。它returns[]。

关于xlwt，基本上，它只是使用您指定的字符串写入一个单元格（带有行和列参数）。

wb = xlwt.Workbook() 
ws = wb.add_sheet('sheet_name')
ws.write(0,0,"content") #Writes the first row, first col, in sheet called "sheet_name".
wb.save("example.xls")

不过，我认为 pandas 更适合这个目的。 xlwt 如果忘记行号和列号，有时会变得非常混乱。如果你能提供一些非空的结果，我可以写一个简单的脚本让你用pandas导出到Excel。

为了在您的示例中使用 pandas，这里是代码。

from bs4 import BeautifulSoup
import requests

url = 'http://www.baseballpress.com/lineups'

soup = BeautifulSoup(requests.get(url).text, 'html.parser')

all_games = []

for g in soup.find_all(class_="game"):
    players = g.find_all('a', class_='player-link')
    game = {
        'time': g.find(class_='game-time').text,
        'weather': g.find(target='forecast').text.strip(),
        'players': [_.text for _ in g.find_all('a', class_='player-link')],
    }
    all_games.append(game)

print(all_games) # This will print out a list of dict that contains the game information

import pandas as pd
df = pd.DataFrame.from_dict(all_games) # Construct dataframe from the list of dict
writer = pd.ExcelWriter('baseball.xlsx') # Init Pandas excel writer, using the file name 'baseball.xlsx'
df.to_excel(writer, 'baseball_sheet') # Writes to a sheet called 'baseball_sheet'. Format follows the Dataframe format.
writer.save() # Save excel

合并片段的最简单方法是使用 ws.write any place you have a print statement. You can use enumerate 来跟踪您的行索引：

from bs4 import BeautifulSoup
import requests
import xlwt  

wb = xlwt.Workbook()  
ws = wb.add_sheet("Batters")  

url = 'http://www.baseballpress.com/lineups'

soup = BeautifulSoup(requests.get(url).text, 'html.parser')

for row, name in enumerate(soup.find_all(class_="players")):
    ws.write(row, 0, name.text)
wb.save("myfirst_xlwt")
