Question

I need help debugging this code.我需要帮助调试此代码。 I am trying to add a csv file to my pandas data frame.我正在尝试将 csv 文件添加到我的 pandas 数据框中。

import pandas as pd
df = pd.read_csv ('batting.csv')
print(df)

When I execute this code I am getting this error:当我执行此代码时出现此错误：

FileNotFoundError: [Errno 2] No such file or directory: 'batting.csv'

I then tried to change the directory using os然后我尝试使用 os 更改目录

os.getcwd()
os.chdir(r"C:\Users\crack\Downloads\excel\batting.csv")

I am now coming across this error:我现在遇到这个错误：

NotADirectoryError: [WinError 267] The directory name is invalid: 'C:\\Users\\crack\\Downloads\\excel\\batting.csv'

I am new to coding and have been looking for a solution to this error all day.我是编码新手，整天都在寻找解决此错误的方法。

Answer 1

You could try,你可以试试

df = pd.read_csv(r"C:\Users\crack\Downloads\excel\batting.csv")

instead of df = pd.read_csv ('batting.csv')而不是df = pd.read_csv ('batting.csv')

Answer 2

You are on the right track.你走在正确的轨道上。 The working directory is probably not where your file is located.工作目录可能不是您的文件所在的位置。

Try doing the following to see where it is:尝试执行以下操作以查看它在哪里：

print(os.getcwd())

The error you are seeing using os.chdir() is because you have specified a filename not a directory.您使用os.chdir()看到的错误是因为您指定了文件名而不是目录。

You have a few possible solutions:您有几种可能的解决方案：

Specify the full path to your CSV file:指定 CSV 文件的完整路径：
```
 pd.read_csv(r"C:\Users\crack\Downloads\excel\batting.csv")
```
Change the working directory to the same folder:将工作目录更改为同一文件夹：
```
 os.chdir(r"C:\Users\crack\Downloads\excel") pd.read_csv("batting.csv")
```
If the script and CSV files are in the same folder and you don't want to specify a fixed path:如果脚本和 CSV 文件在同一个文件夹中并且您不想指定固定路径：
```
 os.chdir(os.path.dirname(os.path.abspath(__file__))) pd.read_csv("batting.csv")
```
This changes the working directory to be where the script is located.这会将工作目录更改为脚本所在的位置。 It takes the full script name and uses just the directory part.它采用完整的脚本名称并仅使用目录部分。
