FileNotFoundError: using Pandas
提问by Aki No Ko
I ran an example, I get the following errors and don't know why.
我跑了一个例子，我得到以下错误，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)
And when I run, I get:
当我跑步时，我得到：

FileNotFoundError: File b'cars.csv' does not exist
I think this is correct code.
我认为这是正确的代码。
I got this code from https://www.learnpython.org/en/Pandas_BasicsThanks, i fixed that

Make sure your file is in the same Directory as your python code, Otherwise you need to give it a directory path. Hope that works!
确保你的文件和你的python代码在同一个目录中，否则你需要给它一个目录路径。希望有效！

It's because you have no cars.csvfile. Open a text editor and create the following file in the same directoryas your .pyfile.
那是因为你没有cars.csv文件。打开文本编辑器并在与您的.py文件相同的目录中创建以下文件。
cars.csv:
汽车.csv：
CarName,Price
Bmw,50000$
Audi,20000$
Ferrari,100000$
Now try running the code. And you'll get the output,
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$
So what pd.read_csv()does is reads a csvfile (default delimiteris ,you can change that too)
那么什么pd.read_csv()是读取csv文件（默认分隔符是,你也可以改变它）

You have to save both your program and cars.csv in same folder if you are using this. cars = pd.read_csv('cars.csv')or you can give full path to your csv file like this (r'C:\Users\Vikas Chauhan\Desktop\cars.csv').
Your code is correct.
如果你正在使用它，你必须将你的程序和cars.csv 保存在同一个文件夹中。cars = pd.read_csv('cars.csv')或者您可以像这样提供 csv 文件的完整路径(r'C:\Users\Vikas Chauhan\Desktop\cars.csv')。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 is
输出是
vikas test
0 vika test2

dataset = pds.read_csv(os.path.join(os.getcwd(),"Data.csv"))
数据集 = pds.read_csv(os.path.join(os.getcwd(),"Data.csv"))
use getcwd to get current directory.
使用 getcwd 获取当前目录。
