多个.csv横着拼接、竖着拼接

import pandas as pd

df1 = pd.read_csv(r'/home/LX/DNN_XGB/Dataset/csv/AAC_N1.csv')#读取第一个文件

df2 = pd.read_csv(r'/home/LX/DNN_XGB/Dataset/csv/CT_N1.csv')#读取第二个文件

df3 = pd.read_csv(r'/home/LX/DNN_XGB/Dataset/csv/LD_N1.csv')#读取第三个文件

file = [df1, df2, df3]

outfile = pd.concat(file, axis=1)#横着拼接
outfile = pd.concat(file)#竖着拼

outfile.to_csv("NegativeYH"+".csv",index=0, sep=',')#输出文件名NegativeYH

print(outfile.shape)#查看文件大小

亲测有效~
