Python ： FileNotFoundError： File b'fleet.csv' 不存在

Question

当我尝试读取目录中的特定CSV文件时，我将获得FileNotFoundError。如果我读了另一个CSV文件，我可以正确阅读它而不会出现任何错误。

我尝试过的

fleet_data=pd.read_csv('data_fleet.csv', sep=',',index_col=0)
fleet_data=pd.read_csv('Users/Ver/Desktop/Processing/data_fleet.csv',sep=',',index_col=0)
fleet_data=pd.read_csv('UsersVerDesktopProcessingdata_fleet.csv',sep=',',index_col=0)
fleet_data=pd.read_csv('data_fleet.csv')

我尝试更改文件的名称，但仍然不起作用。

错误

fleet_data=pd.read_csv('data_fleet.csv', sep=',',index_col=0)

    FileNotFoundError: File b'data_fleet.csv' does not exist

但是

如果我将CSV文件从项目复制到另一个项目文件夹，然后打开Python文件并打开文件（data_fleet.py），我可以毫无任何问题阅读它。

在所需文件夹中读取文件有什么问题？

Answer 1

尝试给它绝对路径：

'C:\Users\Ver\Desktop\Processing\data_fleet.csv'

Answer 2

您可以尝试列出目录的内容吗？例如，使用os模块和listdir()功能

>>> import os
>>> contents = os.listdir()
>>> contents

这将使您查看是否有任何奇怪的字符或阻止您"查找"的东西
