Excel 存储使用Beatifulsoup4解析的数据

我试图将一些有关intrest的信息提取到一个Excel工作表中，该工作表的标题为名称、公式、EXACTMASS、MOLWEIGHT、CAS，但当我运行循环时，它会将每个字母/数字或字节（不确定其术语是否正确）添加到一个单元格中。我希望它存储打印中显示的全部信息，并将其作为字符串存储在每个化合物的每个框中。当下一个链接的循环再次开始时，我希望它在新行中开始。我不确定我会错在哪里

def make_soup(url):
    thepage = urllib.request.urlopen(url)
    soupdata = BeautifulSoup(thepage, "html.parser")
    return soupdata


compoundlist = []
soup = make_soup("http://www.genome.jp/dbget-bin/www_bget?ko00020")

file = open("Compoundlist.csv", "w")
for record in soup.findAll("nobr"):
    compound = ''
    if (record.text[0] == "C" and record.text[1] == '0') or (record.text[0] == "C" and record.text[1] == '1'):
        compoundlist ="http://www.genome.jp/dbget-bin/www_bget?cpd:" + record.text[:6] + '\n'

                MOLWEIGHT = INFO.text
    print(MOLWEIGHT)
    for data in soupcomp.findAll("div", {"style":"width:555px;overflow-x:auto;overflow-y:hidden"}):
            for CAS in soupcomp.findAll("div", {"style":"margin-left:3em"}):
                CAS = CAS.text
    print(CAS)
    with open("Compoundinfo.csv", 'a') as csv_file:
            writer = csv.writer(csv_file)
            writer.writerows([NAMES,FORMULA,EXACTMASS,MOLWEIGHT,CAS])

两件事：

1） 将打开的

（“Compoundinfo.csv”，“a”）作为csv_文件放置在链接列表中项目的
之前：
-无需在每个循环中重新打开文件

2） 对于您的案例，正确的方法是
writer.writerow
（您有
writerows
）

writerow
采用一维数据，
writerows
采用二维数据作为参数
