递归列出文件夹中的文件并解压缩zip文件

Question

I'm trying to recursively list all files inside a folder (including subfolders) and unpack the zip ones. Tha'ts how i'm doing:

def scan(real_path):
    matches = []
    for root, dirnames, filenames in walk(real_path):
        for filename in fil(filenames, '*'):
            matches.append(path.join(root, filename))
    return matches


def unzip(destination, path):
    z = ZipFile(path, mode = "r")
    for archive in z.namelist():
        content = z.read(archive)
        archive = open("%s/%s" % (destination, archive), "w")
        archive.write(content)
        z.close()


def startup_files(starting_over = False):
    print "STARTING FILES AGAIN..." if starting_over else \
          "STARTING FILES..."

    x = scan(folder)
    print "Files found in folder:"
    print x
    for archive in x:
        archive = Archive.details(archive)
        print "READING:", archive.full_path
        if archive.extension == ".ZIP":
            unpack_zip(archive)
            remove(archive.full_path)
            startup_files(True)

Which is causing this bizarre error. I'm testing the script with 2 files, 1.zip and 2.ZIP , in which file i have this file: SFPDB001.GBK

The output is:

Iteration one: ok

STARTING FILES...
Files found in folder:
['arp\\_input\\backups\\1.zip', 'arp\\_input\\backups\\2.ZIP']
READING: C:\Users\G1745 IRON\Development\LL\ARP\arp\_input\backups\1.zip

Iteration two: ok

STARTING FILES AGAIN...
Files found in folder:
['arp\\_input\\backups\\2.ZIP', 'arp\\_input\\backups\\SFPDB001.GBK']
READING: C:\Users\G1745 IRON\Development\LL\ARP\arp\_input\backups\2.ZIP

Iteration three: ERROR: The scan function is finding the right files inside the folder, but the iteration is trying to reach unavailable files.

    z = ZipFile(path, mode = "r")
  File "C:\Python25\lib\zipfile.py", line 339, in __init__
    self.fp = open(file, modeDict[mode])
IOError: [Errno 2] No such file or directory: 'C:\\Users\\G1745 IRON\\Development\\LL\\ARP\\arp\\_input\\backups\\2.ZIP'

I don't have any idea why this is happening... i have a JS background, and i'm starting with python now, so i don't know if i should do something.

OBS: I'm using Python v2.5 because its a legacy code.

Answer 1

I found the error, i should return the startup_files when i call it from the looping:

return self.startup_files(True)

That's all.
