python批量命名图片，并补0

1、批量顺序命名

import os
import re


def ReName(dir_Path, pattern):
    i = 1#可任意修改
    for filename in os.listdir(dir_Path):
        print(filename)
        new_filename = str(i) + ".jpg"
        print(new_filename)
        os.rename(os.path.join(dir_Path, filename), os.path.join(dir_Path, new_filename))
        i = i + 1

    print("Success!")


if __name__ == '__main__':
    dir_Path = r"D:\image_02\data"#路径
    pattern = re.compile(r'.*')
    ReName(dir_Path, pattern)

2、前面补0，实现0000开头

import os
import re
import sys

path = r"D:\image_02\data"3路径
filelist = os.listdir(path)
filetype = '.jpg'
for file in filelist:
    Olddir = os.path.join(path, file)
    if os.path.isdir(Olddir):
        continue
    # os.path.splitext("path")：分离文件名与扩展名
    filename = os.path.splitext(file)[0]
    filetype = os.path.splitext(file)[1]
    print(filename.zfill(5))
    # zfill() 方法返回指定长度的字符串，原字符串右对齐，前面填充0
    Newdir = os.path.join(path, filename.zfill(5) + filetype)  # 数字5是定义为5位数，可随意修改
    print(Newdir)
    os.rename(Olddir, Newdir)
