FileNotFoundError:使用 pandas [英] FileNotFoundError: using Pandas

问题描述

我举了一个例子，出现以下错误，不知道为什么.

I ran an example, I get the following errors and don't know why.

# Import pandas as pd
import pandas as pd

# Import the cars.csv data: cars
cars = pd.read_csv('cars.csv')

# Print out cars
print(cars)

当我跑步时，我得到:

Traceback (most recent call last):
  File "C:/Users/gaara_000/PycharmProjects/firstPj/index.py", line 2, in <module>
    cars = pd.read_csv('cars.csv')

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

我认为这是正确的代码.

I think this is correct code.

推荐答案

这是因为您没有cars.csv文件.打开文本编辑器，并在相同目录中创建与.py文件相同的以下文件.

It's because you have no cars.csv file. Open a text editor and create the following file in the same directory as your .py file.

cars.csv:

CarName,Price
Bmw,50000$
Audi,20000$
Ferrari,100000$

现在尝试运行代码.然后您将得到输出，

Now try running the code. And you'll get the output,

   CarName    Price
0      Bmw   50000$
1     Audi   20000$
2  Ferrari  100000$

所以pd.read_csv()所做的是读取一个csv文件(默认的定界符是,，您也可以更改它)

So what pd.read_csv() does is reads a csv file (default delimiter is , you can change that too)
