#login (user= ' anonymous ', passwd= ', acct= ') Log on to the FTP server, all parameters are optional
#pwd () to get the current working directory
#cwd (path) to set the current working directory to Path
#dir ([path[,...       [, CB]] Displays the contents of the path directory, optional parameter CB is a callback function that is passed to the Retrlines () method
#nlst ([path[,...]) Similar to Dir (), but returns a list of file names rather than displaying them
#retrlines (cmd [, CB]) a given FTP command (such as "RETR filename") for downloading text files. Optional callback function CB is used to process each row of a file
#retrbinary (cmd, cb[,bs=8192[, RA]) is similar to Retrlines (), except that this instruction handles binary files. The callback function CB is used to process each piece of data (the block size defaults to 8K) for downloading.
#storlines (cmd, F) given an FTP command (such as "STOR filename") to upload a text file. To be given a file object F
#storbinary (cmd, f[,bs=8192]) is similar to Storlines (), except that this instruction handles binary files. To be given a file object F, upload block size BS defaults to 8kbs=8192]
#rename (old, new) rename the remote file old to new
#delete (path) deletes a remote file located in path
#mkd (directory) to create a remote directory
#每个需要输入的地方, a troubleshooting check is required. This is just too small a function. But according to the actual situation change, put in BT inside as a small tool can
#有点烂, did not do any try
