业务需求，需要对文件进行批量重命名，于是就研究了下用python实现了，并利用pyinstaller打包py文件成windows可执行的exe文件生成了可执行文件，懒得配置环境的老铁可以下载我打包好的exe执行文件：下面贴出源码：

import os

print('''
输入说明：
*********************回车取默认值**********************
head: 重命名序号的开头，默认为空，以重命名lammy_00001.png则是： lammy_
tail: 重命名序号的结尾：默认和源文件格式相同，如：a.png则是 .png
indexLength: 重命名种序号的位数，如lammy_00001.png，则为00001这部分，indexLength=5
index start:重命名种序号的其实位置，如lammy_00000.png，如果index start = 3，则从lammy_00003.png开始''')

def get_file_tail(file_name):
    tail_index = file_name.rfind('.')
    if tail_index != -1:
        tail_style = file_name[tail_index:len(file_name)]
        return tail_style
    else:
        return ''

srcTail = ''
while True:
    path = input('please input dictionary ： ')
    try:
        fileList = os.listdir(path)
        if len(fileList) > 0:
            srcTail = get_file_tail(fileList[0])
            print("srcTail = " + srcTail)
            break
        else:
            print('the dictionary is null, please input correct dictionary !')
    except Exception as e:
        print('please input correct dictionary !')

head = input('please input head ： ')
tail = input('please input tail ： ')
if tail.strip() == '':
    tail = srcTail

while True:
    indexLength = input('please input indexLength ： ')
    if indexLength.strip() == '':
        indexSize = -1
        break
    else:
        try:
            indexSize = int(indexLength)
            # print('indexSize' + indexSize)
            if len(str(len(fileList))) <= indexSize:
                break
            else:
                print("the input number is too small, is smaller than  number's  length of directory files ：" + len(fileList))
        except ValueError as e:
            print('please input number')

n = 0

while True:
    nString = input('please input index start ： ')
    if nString.strip() == '':
        n = 0
        break
    else:
        try:
            n = int(nString)
            if indexSize == -1:
                break
            if len(str(n + len(fileList) - 1)) <= indexSize:
                break
            else:
                print("the input number is too large, the last file index's number length > indexLength ")
        except ValueError as e:
            print('please input number')

for i in range(len(fileList)):
    oldName = path + os.sep + fileList[i]
    length = len(str(n))
    if indexSize == -1:
        index = str(n)
    else:
        index = (indexSize - length)*'0' + str(n)
    newName = path + os.sep + head + index + tail
    os.rename(oldName, newName)
    print(fileList[i] + "  ------->  " + (head + index + tail))
    n += 1
