Python 为什么'；我的程序写的是；“脚”；进入excel表格？

我试着制作一个程序，从身高和体重表中提取数据，并将其移动到excel上的一个文件中。所有的网页抓取都很好，但当它尝试将信息插入excel时，它只会输入权重。不知道我做错了什么，有什么建议吗

from lxml import html 
import requests 
import xlwt
from xlwt import Workbook

wb = Workbook()
weight = []
feet = []

def scrape():
    list1 = [] 
    user_website = "https://disabled-world.com/calculators-charts/height-weight.php" 
    page = requests.get(user_website) 
    tree = html.fromstring(page.content) 
    list2 = tree.xpath('//td/text()')
    
    for x in list2: 
        list_holder = x.split(" ") 
        for i in list_holder: 
            list1.append(i.lower()) 
    subs = "'" 
    feet = [i for i in list2 if subs in i] 
    print([s.strip('"') for s in feet]) 
    #print([s.replace('\', ') for s in feet]) 
    subs3 = "lb"
    pounds = [i for i in list2 if subs3 in i]
    
    y = 0
    amount = len(pounds)/2
    for x in range(1, int(amount)+1):
        weight.append(pounds[y])
        y += 2
    
    print(weight)

def excel():

    heightweight = wb.add_sheet('HeightWeight')

    x = 1
    y = 0
    amount = len(weight)
    for z in range(1, int(amount)+1):
        heightweight.write(x, 0, weight[y])
        
        x += 1
        y += 1
    print("Done")
    
    x = 1
    y = 0
    amount = len(feet)
    for z in range(1, int(amount)+1):
        heightweight.write(0, x, feet[y])
        
        x += 1
        y += 1
    print("Done")
    
    wb.save("heightweight.xls")

scrape()
excel()

行

foots=[i for i in list2 if subs in i]

创建了一个局部变量，并且不修改全局

foots

。一个快速解决方法是执行

foots.extend（[i for i in list2 if subs in i]）

，但我不希望使用全局变量。
