Here's my attempt:
#!/usr/bin/python
import os
import re
# Search for the files
folder = "~/Desktop/logoFiles/"
pathList = []
for name in os.listdir(folder):
path = os.path.join(folder, name)
# If you want it to be case-insensitive then use
name.upper().startswith("LOGO")
if os.path.isfile(path) and name.startswith("LOGO"):
pathList.append(path)
dList = {}
for x in pathList:
parts = x.split("/")
if parts[-2].isdigit(): # Make sure folder name is a number
n = re.findall(r"(\d+)$", parts[-1]) # Grab number off file
name
if n:
dList[int(n[0])] = "%s<::>LOGO%s\n" % (x, n[0])
keyList = dList.keys()
keyList.sort()
sortedList = "".join(dList[x] for x in keyList)
newFile = open("~/Desktop/logo_stuff/sortedPaths.txt", "w")
newFile.write(sortedList)
newFile.close()
