python folder batch operations
Delete a file folder
for i in os.listdir(path): ##用于返回指定的文件夹包含的文件或文件夹的名字的列表
path_file = os.path.join(path,i) ##连接两个或更多的路径名组件
if os.path.isfile(path_file): ##判断是否为文件
os.remove(path_file) ##对文件进行删除
else: ##如果为文件夹继续进行判断
for f in os.listdir(path_file): ##二级文件夹下文件无法删除，下叙代码进行改进
path_file2 =os.path.join(path_file,f)
if os.path.isfile(path_file2):
os.remove(path_file2)
Delete a folder and secondary folder file
def del_file(path):
for i in os.listdir(path):
path_file = os.path.join(path,i)
if os.path.isfile(path_file):
os.remove(path_file)
else:
del_file(path_file) ##如果不是文件，对文件夹继续进行del_file函数
##执行
path='E:\垃圾分类\文件夹'
del_file(path)
Delete folder txt file
def del_txt(path): ##定义删除txt文件函数
for i in os.listdir(path):
path_file = os.path.join(path,i)
file=os.path.splitext(path_file)
filename,type=file
if type=='.txt': ##如果文件后缀为txt，则删除文件
os.remove(path_file)
##执行
path1='E:\\垃圾分类\\华为数据\\train_data_v2'
del_txt(path1)

##将指定文件放入指定文件夹中，文件夹与文件在同一路径下，且文件夹名称与文件前缀一致

python accessible from anaconda prompt operation, the ratio is more convenient cmd

12.3 Record
(To be separated from the previous record, I can not remember what wrote above, to re)
Create a folder named data in the name
Read package file
File data into 330 categories junk folder name, for example: a banana peel, plastic bags, etc.
import os
import shutil
import pandas as pd
import numpy as np
data=pd.read_csv('E:\\任务分配\\分类表格.csv',sep=',',names=['name']) ##names为文件特征命名
Defined functions, create folders
def creDir():
root = 'E:\\任务分配\\合并图片\\图片分类1\\' ##文件夹创建路径
i=0
for j in range(333):
file_name = root + str(data.name[i])
os.mkdir(file_name)
i=i+1
creDir()
The picture merge different folder in the same subfolder
(Example: a banana peel under name1 folder picture combined with the next name2 banana peel folder, the code for the 333 class folder batch merge, using the file name as the index to find)
SOURCE_DIR = r'E:\任务分配\合并图片\图片'
root= 'E:\\任务分配\\合并图片\\图片分类1\\'
##rb = open_workbook('m:\\1.xls')
i=0
for j in range(333):
COPY_DIR =data.name[i]
TARGET_DIR=root+str(data.name[i])
for dir_path, sub_dirs, files in os.walk(SOURCE_DIR, True):
if os.path.split(dir_path)[-1] == COPY_DIR:
for file in files:
shutil.copyfile(os.path.join(dir_path, file), \
os.path.join(TARGET_DIR, file))
## ws = rb.get_sheet(0)
## ws.write(0,i,)
## wb.save('m:\\1.xls')
i=i+1
The different folders erupted in the same folder name picture merge into the same folder
(Looking source_dir with copy_dir the same file name, to copy all put in target_dir)
##函数编辑
SOURCE_DIR = r'E:\任务分配\合并图片\图片'
TARGET_DIR=r'E:\\任务分配\\合并图片\\图片分类\\零食'
COPY_DIR ='零食'
for dir_path, sub_dirs, files in os.walk(SOURCE_DIR, True):
if os.path.split(dir_path)[-1] == COPY_DIR:
for file in files:
shutil.copyfile(os.path.join(dir_path, file), \
os.path.join(TARGET_DIR, file))
##运行
SOURCE_DIR = r'E:\任务分配\合并图片\图片'
dir_path=os.walk(SOURCE_DIR, False)
Delete the specified file path
##读入有争议图片
data1=pd.read_csv('E:\\任务分配\\有争议图片.csv',sep=',',names=['file','name'])
data1.file[1]
##删除文件
i=1
for j in range(44):

i=i+1
Bulk copy files to a specified folder
##读入有争议图片
from shutil import copyfile
data2=pd.read_csv('E:\\任务分配\\最终有争议图片##批量复制文件到指定文件夹
##创建特定文件夹
i=1
root='E:\任务分配\最终有争议图片\有争议图片\\'

##放置有争议图片
for j in range(912):
