Renaming a batch Python script

The copy of ********.bmp or copy of copy of ********.bmp such files are uniformly named ********0.bmp or ********00.bmp format, and the number of the following 0 represents ********. The number of BMP occurrences +1. Wrote a small script below:

The code is as follows:

Import OS
"""
This program is used to rename the file name because there are many copy of the file name in the folder, so remove Windows
Rename style and replace with new additive naming mechanism

"""
def getfilenames (dirs, dict):
#dir为目录名, LST list
Filenames=os.listdir (dirs)
For name in filenames:
Key = Filenames[filenames.index (name)]
Sign = "Copy of"
Judge = Key.find (sign)
if (Judge! =-1):
Dict[key] = 1
else: #提取其中的真实文件名
truekey= key[-12:] #因为真实的文件名都是在12位
If Truekey not in Dict: #字典中不存在
Dict[truekey]=1
Os.rename (Dirs+str (OS.SEP) +name,dirs+str (OS.SEP) +truekey)
Else
#split Finames
newkey= str (truekey[:-4]) +str (' 0 ' *dict[truekey]) + str (truekey[-3:])
Dict[truekey] = dict[truekey]+1
Os.rename (Dirs+os.sep+name,dirs+os.sep+newkey)

If ' __name__=__main__ ':
dict={}
dirs = "C://temp"
GetFileNames (dirs, Dict)

Use of the dictionary, the use of the OS module, learned something, hehe!
