Question

首先...我是python的新手，这不是我的代码。我只是试图找出为什么代码无法正常工作。 这就是代码：

from PIL import Image
import sys, os, errno

exported = 0

def search(file):
  f = open(file, "rb")
  offset = 0
  chunk = 1000000000;
  skinlist = list()
  found = -1
  foundstr = -1
  while 1:
    f.seek(offset)
    data = f.read(chunk)
    dataSize = len(data)

    if foundstr == -1:
      foundstr = data.find("/Game/UI/Foundation/Textures/Icons/Heroes/Athena/Soldier/T-Soldier-HID-001-Athena-Commando-F-L")
      if foundstr >= 0:
        print("NOW SEARCHING FOR NAMES")
        f.seek(offset) 
        findStrings(f, data, offset, skinlist, foundstr - 1)
        offset += dataSize
        continue
    if foundstr >= 0:
      findStrings(f, data, offset, skinlist, -1)

    if found == -1:
      found = data.find("\xFA\xC5\x99\x20\xCC\x85\x5C\x4B\x90\x05\xEC\xB6\x58\xA7\x3F\x71\x0C")
      if found >= 0:
        print("NOW EXPORTING TEXTURES")
        f.seek(offset) 
        export(f, data, offset, skinlist, found)
        offset += dataSize
        continue
    if found >= 0:
      f.seek(offset) 
      export(f, data, offset, skinlist, -1)
    print("READING...")
    offset += dataSize
    if dataSize < chunk:
      print("Finished file!")
      break
  print(str(exported - 1) + " exported!")
  f.close()


def findStrings(f, data, offset, skinlist, start):
  while 1 : 
    start = data.find("/Game/UI/Foundation/Textures/Icons/Heroes/Athena/Soldier/", start + 1)
    if start == -1:
      break
    end = data.find("\x00", start)
    if end != -1 and end - start < 200:
      f.seek(offset + start)
      name = f.read(end - start)
      if((name.endswith("-L") or name.endswith("_L")) and "." not in name and "T-Soldier-HID-035-Athena-Commando-M-Medieval-L" not in name and name not in skinlist):
        print("FOUND: " + name)
        skinlist.append(name)

def export(f, data, offset, skinlist, start):
  while 1 :     
    start = data.find("\x50\x46\x5F\x44\x58\x54\x35\x00\x00\x00\x00\x00\x01\x00\x00\x00\x01\x00\x00\x00\x48", start +1)
    #print(start)
    if start == -1:
      break
    end = data.find("\x00\x00\x00\x00\x00\x00\x00\xC1\x83\x2A\x9E", start)
    # print(end)
    if end != -1 and end - start == 262197:
      end =  end - 7
      name = skinlist[exported]
      name = name[name.rfind("/") + 1:]
      print("FOUND BYTES FOR: " + name)
      print(offset + start)
      try:
        skip = 40
        f.seek(offset + end - 1)
        size = f.read(1)
        dds = open("images/" + name + ".dds", "w+b")
        dds.write("\x44\x44\x53\x20\x7C\x00\x00\x00\x07\x10\x08\x00\x00" + size + "\x00\x00\x00" + size + "\x00\x00\x00\x00\x04\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x4E\x56\x54\x54\x06\x00\x02\x00\x20\x00\x00\x00\x04\x00\x00\x00\x44\x58\x54\x35\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00")
        f.seek(offset + start + skip)
        length = end - start - skip - 6
        dds.write(f.read(length))
        #print("LENGTH: " + str(length))
        dds.close()
        Image.MAX_IMAGE_PIXELS = None
        im = Image.open("images/" + name + ".dds")
        im.save("images/" + name + ".png")
        os.remove("images/" + name + ".dds")


        exported
        exported += 1
        print("EXPORTED: " + name + "  " + str(exported) + " / " + str(len(skinlist)))
        if len(skinlist) == exported:
          print("Finished list! Exported: " + str(exported))
          f.close()
          sys.exit(0)
      except Exception as inst:
        print(inst)

if __name__ == '__main__':
  if len(sys.argv) <= 1:
    sys.exit("[Error] Usage: IconExporter.py <file>")

  inFile = sys.argv[1]
  search(inFile)

此代码应在.pak文件中找到图标，并将其复制到名为images的文件夹中。它没有显示错误。但是它不能正常运行。如果我运行它，输出为：

   -WindowsClient.pak 
READING...
Finished file!
-1 exported!

，但不导出任何内容。可以给我解释一下为什么。
