【问题描述】：

我们正在尝试使用 pythonanywhere.com 主机中的 view.py 读取 csv 文件。我们希望从 1.csv 文件的每一行中获取三个单元格（id、语句和段落），直到最后一个。

代码是：

def home(request):

    Stats = Statments.objects.all()

    __file__ = '1.csv'

    module_dir = os.path.dirname(__file__)  # get current directory
    file_name = os.path.join(module_dir, 'Politi_Stat/1.csv')

    #Load statments to database from CSV
    with open(file_name,"r", encoding = 'utf-8') as csv_file:
        csv_reader = csv.reader(csv_file, delimiter=',')
        for row in csv_reader:
            book = Statments(id = row[0] ,statment=row[1], Paragraph=row[2])
            book.save()


    d = deque(posts)
    d.extendleft(reversed(Stats))

我们导入 csv 和 os。好像是csv的unicode UTF-8的编码问题。

网站的输出是：服务器 500

日志文件的输出是：

【问题讨论】：

csv 文件不是 UTF-8 编码的。它是在 Windows 机器上创建的吗？
在 Mac OS 上创建。但我现在使用的是 Windows。
如果 csv 文件不是 utf-8 编码，那么您的代码将无法工作
好的，感谢您的通知。

标签： python django csv encoding utf-8

【解决方案1】：

您的 csv 似乎不是 utf8 编码的。加载时将 utf8 指定为编码。加载文件时为文件指定正确的编码，它将起作用。
