文件的批量重命名

import os

        self.path = 'E:\Python_os_study\image'

    def rename(self):
        filelist = os.listdir(self.path)

                dst = os.path.join(os.path.abspath(self.path),  format(str(i), '0>10s') + '.jpg')
                os.rename(src, dst)
                print ('converting %s to %s ...' % (src, dst))
                i = i + 1
        print ('total %d to rename & converted %d jpgs' % (total_num, i))

    newname.rename()



#获取绝对路径
print(os.path.abspath("osStudy"))
#就是获取当前目录，并组合成新目录
filelist = os.listdir("C:\\Users\\frank804\\Desktop\\test")
#os.getcwd() 获取当前文件所在路径
print(os.getcwd())
#路径组合
#dst = os.path.join(os.path.abspath(self.path),  format(str(i), '0>10s') + '.jpg')
print(os.path.join(os.getcwd(),'data'))
#格式转换，当数位不够时用哪个领来填充
print(format(str(11), '0>10s'))
