Question

我举了一个例子，我收到了以下错误，并且不知道为什么。

# 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。

我从https://www.learnpython.org/en/Pandas_Basics获得了此代码谢谢，我修好了

Answer 1

确保您的文件与python代码位于同一目录中，否则您需要为其指定目录路径。希望有用！

Answer 2

这是因为你没有cars.csv个文件。打开文本编辑器，在同一目录中创建与.py文件相同的文件。

cars.csv：

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

现在尝试运行代码。你会得到输出，

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

pd.read_csv()所做的是读取csv文件（默认分隔符是,，您也可以更改它）

Answer 3

如果您使用此程序，则必须将程序和cars.csv保存在同一文件夹中。 cars = pd.read_csv('cars.csv')或者您可以像(r'C:\Users\Vikas Chauhan\Desktop\cars.csv')这样提供完整的csv文件路径。你的代码是正确的。

import pandas as pd

cars = pd.read_csv(r'C:\Users\Vikas Chauhan\Desktop\cars.csv')

# Print out cars
print(cars)

OutPut

  vikas   test
0  vika  test2

Answer 4

数据集= pds.read_csv（os.path.join（os.getcwd（），“ Data.csv”））

使用getcwd获取当前目录。

FileNotFoundError：使用Pandas
