不懂为何就是读不了文件，代码有问题吗？多谢指教

Question

import numpy as np
import pandas as pd
inputfile = 'D:\软件\python\《Python数据分析与挖掘实战(张良均等)》中文PDF+源代码\《Python数据分析与挖掘实战(张良均等)》中文PDF+源代码\数据及代码\chapter13\demo\data\datal.csv'
date=pd.read_csv(inputfile)
r = [data.min(), data.max(), data.mean(), data.std()] # 依次计算最小值、最大值、均值、标准差
r = pd.DataFrame(r, index=['Min', 'Max', 'Mean', 'STD']).T # 计算相关系数矩阵
np.round(r, 2) # 保留两位小数

运行如下：

inputfile = 'D:\软件\python\《Python数据分析与挖掘实战(张良均等)》中文PDF+源代码\《Python数据分析与挖掘实战(张良均等)》中文PDF+源代码\数据及代码\chapter13\demo\data\datal.csv'

把这里的 \ 换成 \\ 看看，如果还不行，把csv放在一个没有中文的路径下面。你这个提示是文件没有找到
