Question

我想使用Pandas将本地计算机中的CSV文件包含到Jupyter Notebook中，但是每次出现文件未找到错误。

我尝试包含使用不同目录的文件以及在文件路径之前使用r的文件。

import numpy as np 
import pandas as pd
import warnings
warnings.filterwarnings('ignore')
df=pd.read_csv(r'C:\Users\shrey\Desktop\MINDTREE.csv')

The error message I am getting is the following:
    --------------------------------------------------------------------------
    FileNotFoundError                         Traceback (most recent call last)
    <ipython-input-23-d0297c50883f> in <module>()

    FileNotFoundError: File b'C:\\Users\\shrey\\Desktop\\MINDTREE.csv' does not exist

Answer 1

'\'是python中的转义字符，Windows使用它们来分隔路径。

尝试使用：

df=pd.read_csv('C:\\Users\\shrey\\Desktop\\MINDTREE.csv')

或

df=pd.read_csv('C:/Users/shrey/Desktop/MINDTREE.csv')

Answer 2

您可以将csv放入保存jupyter笔记本的目录中，也可以只使用熊猫read_csv

df=pd.read_csv('C:\\Users\\shrey\\Desktop\\MINDTREE.csv')

如何在Jupyter Notebook中打开CSV文件？
