python批量改名

非递归版

参考python批量改名

要用到 os 模块下的几个方法

1、os.listdir(‘/root/python/’) #列出当前目录下所有文件
2、os.path.isdir(‘/abc’) #判断是否是目录，返回布尔值，不存在也返回false
3、os.path.isfile(‘/etc/passwd’) #判断是否是文件
4、os.path.join(‘/etc/’, ‘passwd’) #连接文件，返回/etc/passwd

改名并移动到指定目录

import os
import shutildef mvFile(src,dst):fileType = [".png"]   endswith_tuple = tuple(fileType)#print('src:',src)srcPath = os.listdir(src)for old_name in srcPath:#print(old_name)#print('')if old_name.endswith(endswith_tuple): src_path = os.path.join(src, old_name)des_path = os.path.join(dst, old_name)#print('src_path',src_path)#print('des_path',des_path)shutil.move(src_path, des_path)else :continuereturnif __name__ == '__main__':src = "F:\\Baidu\\视频"dst = "F:\\Baidu\\视频\\video"for i in range(1,6) :srcDay  = 'day'+ str(i)srcDayPath = os.path.join(src, srcDay)videolist  = os.listdir(srcDayPath)print()print()print()for old_name in videolist:#print(srcDay,old_name)new_name = '0'+ str(i) + old_name#print(os.path.join(srcDayPath,old_name))#print(os.path.join(srcDayPath,new_name))os.rename(os.path.join(srcDayPath,old_name),os.path.join(srcDayPath,new_name))shutil.move(os.path.join(srcDayPath,new_name), os.path.join(dst,new_name))#print(os.path.join(dst,new_name))#mvFile(src,dst)

数字补零
使用python3的数字格式化方法。
下表展示了 str.format() 格式化数字的多种方法：

>>> print("{:.2f}".format(3.1415926))
3.14

表格

数字	格式	输出	描述
3.1415926	{:.2f}	3.14	保留小数点后两位
3.1415926	{:+.2f}	+3.14	带符号保留小数点后两位
-1	{:-.2f}	-1.00	带符号保留小数点后两位
2.71828	{:.0f}	3	不带小数
5	{:0>2d}	05	数字补零 (填充左边, 宽度为2)
5	{:x<4d}	5xxx	数字补x (填充右边, 宽度为4)
10	{:x<4d}	10xx	数字补x (填充右边, 宽度为4)
1000000	{:,}	1,000,000	以逗号分隔的数字格式
0.25	{:.2%}	25.00%	百分比格式
1000000000	{:.2e}	1.00e+09	指数记法
13	{:>10d}	13	右对齐 (默认, 宽度为10)
13	{:<10d}	13	左对齐 (宽度为10)
13	{:^10d}	13	中间对齐 (宽度为10)

查找并删除mp4文件

查找
将当前目录及其子目录下所有文件后缀为 .mp4 的文件列出来:

find . -name "*.mp4"

查找并删除

find . -name '*.mp4' -type f -print -exec rm -rf {} \;

分析：

(1) “.” 表示从当前目录开始递归查找

(2) “ -name ‘*.mp4’ "根据名称来查找，要查找所有以.mp4结尾的文件夹或者文件

(3) " -type f "查找的类型为文件

(4) “-print” 输出查找的文件目录名

(5) 最主要的是是-exec了，-exec选项后边跟着一个所要执行的命令，表示将find出来的文件或目录执行该命令。
exec选项后面跟随着所要执行的命令或脚本，然后是一对儿{}，一个空格和一个斜扛，最后是一个分号.
