在未引用字段中看到的CSV新行字符错误

问题描述

以下代码一直运行到今天，当我从Windows计算机导入并收到此错误：

the following code worked until today when I imported from a Windows machine and got this error:

在非引号字段中看到的新行字符 - 需要在通用换行模式下打开文件？

import csv

class CSV:


    def __init__(self, file=None):
        self.file = file

    def read_file(self):
        data = []
        file_read = csv.reader(self.file)
        for row in file_read:
            data.append(row)
        return data

    def get_row_count(self):
        return len(self.read_file())

    def get_column_count(self):
        new_data = self.read_file()
        return len(new_data[0])

    def get_data(self, rows=1):
        data = self.read_file()

        return data[:rows]

如何解决此问题？

def upload_configurator(request, id=None):
    """
    A view that allows the user to configurator the uploaded CSV.
    """
    upload = Upload.objects.get(id=id)
    csvobject = CSV(upload.filepath)

    upload.num_records = csvobject.get_row_count()
    upload.num_columns = csvobject.get_column_count()
    upload.save()

    form = ConfiguratorForm()

    row_count = csvobject.get_row_count()
    colum_count = csvobject.get_column_count()
    first_row = csvobject.get_data(rows=1)
    first_two_rows = csvobject.get_data(rows=5)

推荐答案

这将是很好看的csv文件本身，但这可能适合你，给it a try，replace：

It'll be good to see the csv file itself, but this might work for you, give it a try, replace:

file_read = csv.reader(self.file)

与：

file_read = csv.reader(self.file, dialect=csv.excel_tab)

或者，使用<$ c $打开一个文件c>通用换行模式并将其传递给 csv.reader ，如：

Or, open a file with universal newline mode and pass it to csv.reader, like:

reader = csv.reader(open(self.file, 'rU'), dialect=csv.excel_tab)

或者，使用 splitlines（），如下所示：

Or, use splitlines(), like this:

def read_file(self):
    with open(self.file, 'r') as f:
        data = [row for row in csv.reader(f.read().splitlines())]
    return data
