使用Panda在Python中读取CSV错误

Question

我想读一个csv文件

import pandas as pd
import numpy as np
import matplotlib as plt
from pandas import DataFrame

df = pd.read_csv(r'C:\Andy\DataScience\python\Loan_Prediction\Train.csv') 
df.head(10)

但是如下所示得到错误

IOError: File Train.csv does not exist 

但该文件确实存在于该位置。

Answer 1

如果使用反斜杠，因为它是Python中的特殊字符，您必须记住转义每个实例

import pandas as pd
import numpy as np
import matplotlib as plt
from pandas import DataFrame

df = pd.read_csv(r'C:\\Andy\\DataScience\\python\\Loan_Prediction\\Train.csv') 
df.head(10)

Answer 2

你的read_csv无法找到你必须提供正斜杠的csv的路径

import pandas as pd
import numpy as np
import matplotlib as plt
from pandas import DataFrame

df = pd.read_csv('C:/Andy/DataScience/python/Loan_Prediction/Train.csv') 

如果再次出现错误，则只需加倍斜杠即可避免任何特殊字符。

df = pd.read_csv('C://Andy//DataScience//python//Loan_Prediction//Train.csv')

df.head(10)
