想在原来txt文件每行文件后面增加内容
label=2
ff = open('./img_0505_128/train1.txt','w') #打开一个文件，可写模式
with open('./img_0505_128/train.txt','r') as f: #打开一个文件只读模式
line = f.readlines()
i = 0
for line_list in line:
line_new =line_list.replace('n','') #将换行符替换为空('')
b = str(label) #主要是这一步 将之前列表数据转为str才能加入列表
line_new = line_new +'.jpg '+b +'n'
i += 1
print(line_new)
ff.write(line_new) #写入一个新文件中
train.txt
