如何使用python重命名每个文件夹中以'1'开头的数字重命名文件？

Question

i'm trying to rename files numerically in multiple folders but it seems that the count continues to run through all the files and not starting from '1' each folder. what should i do?

i have tried the following code:

for folderName, subfolders, filenames in os.walk(path):
    for f in filenames:
        f_name, f_ext = os.path.splitext(f)
        f_name = str(count)
        count = count + 1

  new_name = '{}{}'.format(f_name, f_ext)          
  os.rename(os.path.join(folderName,f),os.path.join(folderName,new_name))


i expect the output renaming of the files to be:
files in folder 1: 1.tif, 2.tif, 3.tif, 4.tif 
files in folder 2: 1.tif, 2.tif, 3.tif
files in folder 3: 1.tif, 2.tif, 3.tif, 4.tif 

but the actual outcome is:
files in folder 1: 1.tif, 2.tif, 3.tif, 4.tif 
files in folder 2: 5.tif, 6.tif, 7.tif
files in folder 3: 8.tif, 9.tif, 10.tif, 11.tif

This should work:

for folderName, subfolders, filenames in os.walk(path):
    count = 1   # << -- here are the changes
    for f in filenames:
        f_name, f_ext = os.path.splitext(f)
        f_name = str(count)
        count += 1
