Depth study of the picture there is often a batch rename, sort data from the Internet to see what the future for easy viewing.

Import OS 

class BatchRename ():
     '' ' 
    batch rename folder picture file 
    ' '' 
    DEF  the __init__ (Self): 
        self.path = ' C: / the Users / JingPan / Desktop / data_json '   # represents treatment needs to be named folder 

    DEF the rename (Self): 
        Filelist = the os.listdir (self.path) # acquires the file path 
        TOTAL_NUM = len (Filelist) # Get file length (number) 
        I = 1   # represents a file name starting from 1 
        for Item in Filelist:
             IF item.endswith ( ' .json ' ):  # Original picture format is jpg format (or the source file is png format and other formats, the latter format can be converted to a format adjusted to their needs) 
                src = os.path.join (os.path.abspath ( self.path), Item)
                 # DST = the os.path.join (os.path.abspath with (self.path), '' + STR (I) + '.jpg') # format is also processed, jpg Of course this can be changed png format 
                DST = the os.path.join (os.path.abspath with (self.path), ' 000 ' + the format (STR (I), ' 0> 3S ' ) + ' .json ' )       # naming format in this case is 000000.jpg form the desired format autonomously define 
                the try : 
                    os.rename (the src, DST) 
                    Print ( ' Converting% to S% S ... ' % (src, dst))
                    i = i + 1
                except:
                    continue
        print ('total %d to rename & converted %d jpgs' % (total_num, i))

if __name__ == '__main__':
    demo = BatchRename()
