python合并两个txt文件内容-yolo格式数据

import os



def concattxt(path1,path2):
        num = 0
        pathdir1 = os.listdir(path1)#获取第一部分txt文件夹中的文件列表

        for txtname in pathdir1:
                #name1 = os.path.splitext(txtname)[0]#获取当前txt文件名字
                #txtfile1 = open(txtpath1+name1, "rb")
                #txtfile2 = open(txtpath2+name1, "rb")
                txtfilepath1 = path1+txtname
                txtfilepath2 = path2+txtname
                txt1 = open(txtfilepath1,'a+', encoding='utf-8')
                if os.path.exists(txtfilepath2):
                        num = num+1
                        with open(txtfilepath2, 'r', encoding='utf-8') as txt2:
                                #txt1.write('n')
                                for i in txt2:
                                         txt1.write(i)
        print('the concat txt num is:',num)

    txtpath1 = '/home/jun/work/2021Z001/test/ann/'
    txtpath2 = '/home/jun/work/2021Z001/test/labels/'
    concattxt(txtpath1,txtpath2)
 
 

txt1中的原始数据

txt2中的原始数据

合并后txt1中的数据
