Question

所以我有一个脚本需要在服务器上以不同的间隔做3件事。

如果下载（使用子流程）
扫描位置1，如果存在文件，则根据文件的来源移动文件并重命名（使用子进程），
扫描目录，如果文件存在则将文件上传到不同的FTP（使用子进程）。

除此之外一切都很好;在第3次扫描（与第2次扫描相同）由于某种原因，脚本不想超越“for root，dirs，files in”

import sys
import os
import subprocess 
import time
import datetime
from datetime import datetime as dt

# Local Directories 
N_dir_dest = '/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/N_dest' # Directory where the      NICK source video files needs to be downloaded to
M_dir_dest = '/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/M_dest' # Directory where the     NICK source video files needs to be downloaded to
encode_dest1 = '/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/encode_dest1' # Encoding Directory where source videos are moved to after being downloaded and renamed
encodeDrop_dir = '/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/encodeDrop_dir' # Files ready for uploading to BeeCell FTP 

#Script Starts

while True:
        time.sleep(10)
        if dt.now().hour in range(20, 23):
            print "Starting to Scan UK FTP for source files - time is: %s" % dt.now()
            thedownloadprocess = subprocess.Popen([sys.executable, "/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/BeeCell_FTP_incoming.py"])
            thedownloadprocess.communicate()
            time.sleep(3600)


        elif dt.now().minute in range(01, 15) or dt.now().minute in range(31, 45):
            time.sleep(10)
            print "Scanning %s and %s - time is: %s" % (N_dir_dest, M_dir_dest, dt.now())
            for root, dirs, files in os.walk(N_dir_dest) or os.walk(M_dir_dest):
                for file in files:
                    path_to_file = os.path.join(root, file)
                    if os.path.isfile(path_to_file) and file.endswith(('.mov', '.mpg', '.mp4')):
                        print "file: %s found - starting rename process" % path_to_file
                        renameprocess = subprocess.Popen([sys.executable, "/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/BeeCell_rname_files.py"])
                        renameprocess.communicate()
                        print "Finished Rename and encode - sleeping for 10 secs- time is: %s" % dt.now()
                        time.sleep(10)
                    else:
                        print "No files in %s or %s" % (N_dir_dest, M_dir_dest)
                        time.sleep(20) 



        elif dt.now().minute in range(16, 30) or dt.now().minute in range(46, 00): # checking every 120 seconds in the minute range 20 - 59
            time.sleep(10)
            print "scanning %s - time is: %s" % (encodeDrop_dir, dt.now())
            for root, dirs, files in os.walk(encodeDrop_dir):
                for file in files:
                    path_to_file = os.path.join(root, file)
                    if os.path.isfile(path_to_file) and file.endswith(('.mov', '.mpg', '.mp4')):
                        print "file: %s will be uploaded"
                        Nuploadprocess = subprocess.Popen([sys.executable, "/Volumes/VoigtKampff/Temp/_Jonatha/BeeCell/BeeCell_FTPupload.py"]) 
                        Nuploadprocess.communicate()
                        print "Finished Upload - sleeping for 10 secs- time is: %s" % dt.now()
                        time.sleep(10)
                    else:
                        print "No files in %s" % encodeDrop_dir
                        time.sleep(10)

        else:
            print "Relaxing"

当我运行脚本时，第一个“elif”运行正常并启动子进程，如果在目录中找到一个文件 - 但在第二个“elif”它只是循环这个：

elif dt.now().minute in range(16, 30) or dt.now().minute in range(46, 00): # checking every 120 seconds in the minute range 20 - 59
            time.sleep(10)
            print "scanning %s - time is: %s" % (encodeDrop_dir, dt.now())
            for root, dirs, files in os.walk(encodeDrop_dir):

循环继续，直到dt.now（）范围继续。我看不出第一个“elif”和第二个“elif”之间的代码有什么不同 - 我愿意在过去几天破坏我的大脑之后听到任何建议，试图弄清楚出了什么问题！ ??

确定添加了打印功能：

    print "scanning %s - time is: %s" % (encodeDrop_dir, dt.now())
            print "Upload List: %s" % E_dir_oslist
            for root, dirs, files in os.walk(encodeDrop_dir):
                print "hello"
                for file in files:
                    print "hello 1"

这是输出：

scanning / Volumes / VoigtKampff / Temp / _Jonatha / BeeCell / encodeDrop_dir - 时间是：2013-03-19 18：22：25.345483

您好

更新：如果我将扫描功能移动到子进程调用的脚本中 - 它可以工作。我还没有发现如果以上述方式使用它会失败的原因。

python扫描文件目录
