问题 I'm trying to load a CSV file to Amazon S3 with Python. I need to know CSV file's modification time. I'm using ftplib to connect FTP with Python (2.7). 回答1: MLST or MDTM While you can retrieve a timestamp of an individual file over FTP with MLST or MDTM commands, neither is supported by ftplib. Of course you can implement the MLST or MDTM on your own using FTP.voidcmd. See: 3. File Modification Time (MDTM) 7. Listings for Machine Processing (MLST and MLSD) A simple example for MDTM : from

问题 I am trying to download a certain file (named 010010-99999-year.gz) from an FTP server. This same file, but for different years is residing in different FTP directories. For instance: ftp://ftp.ncdc.noaa.gov/pub/data/noaa/isd-lite/2000/010010-99999-1973.gz ftp://ftp.ncdc.noaa.gov/pub/data/noaa/isd-lite/2001/010010-99999-1974.gz and so on. The picture illustrates one of the directories: The file is not located in all the directories (i.e. all years). In such case I want the script to ignore

问题 I have a Python Flask app that gets request to download a file from a remote FTP server.

问题 How can I set a timeout of 10~ seconds and if it fails to upload or times out to try again? Current code: print "Uploading LIST{}.html".format(counter) ftp_session = ftplib.FTP('ftp.website.com','admin@website.com','password123') rss_ftp_file = open('OUTPUT/LISTS/LIST{}.html'.format(counter),'r') ftp_session.cwd("/LISTS/") ftp_session.storlines('STOR LIST{}.html.tmp'.format(counter), rss_ftp_file) rss_ftp_file.close() ftp_session.rename('LIST{}.html.tmp'.format(counter), 'LIST{}.html'.format

问题 Initial Post I have a very long running program where about 97% of the performance is tied up in socket objects created by ftp.retrlines and ftp.retrbinary calls. I have already used processes and threads to parallelize the program. Is there anything else I can do to eek out some more speed? Example code: # Get file list ftpfilelist = [] ftp.retrlines('NLST %s' % ftp_directory, ftpfilelist.append) ... filter file list, this part takes almost no time ... # Download a file with open(path, 'wb')
