如何阅读csv避免索引？

Question

CSV数据是这样的：

,fixed acidity,volatile acidity,citric acid,residual sugar,chlorides,free sulfur dioxide,total sulfur dioxide,density,pH,sulphates,alcohol,quality 
0,7.0,0.27,0.36,20.7,0.045,45.0,170.0,1.001,3.0,0.45,8.8,6 
1,6.3,0.3,0.34,1.6,0.049,14.0,132.0,0.994,3.3,0.49,9.5,6 

，我想这是我的计划：

​​

我想要的结果是7.0,0.27,0.36,20.7,0.045,45.0,170.0,1.001,3.0,0.45,8.8,6，但说到0,7.0,0.27,0.36,20.7,0.045,45.0,170.0,1.001,3.0,0.45,8.8。那么如何避免索引栏？

Answer 1

有问题您的数据在第一次,没有转换为索引之前，所以需要index_col=[0]。然后调用后.values第一列被遗漏：

data = pd.read_csv('train.csv',delimiter=',', index_col=[0]) 

或者：

data = pd.read_csv('train.csv', index_col=[0])
