问题 I am trying to save multidimensional lists into a file, while keeping the structure of the lists. I figured using pickle would be the easiest: for ... stuff: # stuff happens which creates the new list kWebsTemp that I want to save # now for every loop-run I want to append my file by adding the new list as an additional object with open('%s_%s' %(filename,Scent), 'wb') as file: #file.write(kWebsTemp) #file.write('\n') pickle.dump(kWebsTemp, file) If I now however try to load the lists, I am

问题 I'm looking into using ftplib (and possibly ftputil) for doing some automated FTP file syncing. I have a couple of servers to test this against at the moment, but, whilst I'm having a successful conversation with both servers, I get EOFError-s with each error reply. For example: if I try to log in with an incorrect user/pass, I will get the 530 response with everything... but I also get an EOFError; if I login with a correct user/pass or try to dir() after doing so etc., I get no EOFError. It

问题 The official documentation doesn't specify. I understand EOFError means "End of file error", but what exactly does that mean? If a file reader reaches the end of a file, that doesn't sound like an error to me. 回答1: EOFError is handy in all of IO, the class which is the basis of all input/output in ruby. Now also remember core Unix concepts: everything is a file. This includes sockets. So, if you have some socket open and are reading from it, an exceptional condition might be to encounter an

问题 Use Case: Dowload hundred of thousands of xmls files (size from bytes to 50 mb/file) structured like this /year-month/year-month-day/hours/files with ftplib. So i loop through each hour folder for a given day and for each one i store all the filenames with ftp.nlst(), then i loop through each filename and i donwload the concerned file like this. with open(local_file, 'wb') as fhandle: try: ftp.retrbinary('RETR ' + filename, fhandle.write) except EOFError: try: fhandle.close() os.remove(local

问题 I wrote the following for a homework assignment and it works fine in IDLE and Eclipse running Python 3. However, I tried to run it from TextMate with the new line 1 -- which I found here -- to point it to Python 3 on the Mac. It seems to be running Python 3 but returns an error. It says: EOFError: EOF when reading a line. It's referring to line 5 below. Anyone know why? BTW, this TextMate issue is not part of the homework assignment, so I'm not trying to get homework help. I just want to

问题 I have written a small script that helps me solve scrabble and word-warp problems. It works fine when I run it from Mac OS X terminal. I would like to share the script with my friends as a standalone Mac app. Hence I used py2app for this, but the App crashed when I double-click on it. The console shows the following error message: 1/17/11 2:13:51 PM [0x0-0x4a44a4].org.pythonmac.unspecified.warp[9875] Enter letters: Traceback (most recent call last): 1/17/11 2:13:51 PM [0x0-0x4a44a4].org

问题 I am trying to get input from the user at the command prompt. The program reads in data from a text file in the manner of "cat text.txt | ./thescript.py" At the point of the script in question, all data has already been read in, processed, and put into a list of lists. Now I am iterating through that list of lists looking for questionable items. The code basically looks like this: for invoice in parsedlist: if invoice[-1] == 3: sys.stderr.write("triple duplicate at " + invoice[2]+' : ' +

问题 I was solving a problem on HackerRank when I encountered the following problem in my code. I tested it out on my Python (2.7.10) IDLE , and it was working fine. But it showed the following error on HackerRank: Traceback (most recent call last): File "solution.py", line 13, in <module> input_2=input() EOFError: EOF when reading a line I entered the following code: import sys input_2="" n=int(input()) m=0 l=0 array=[] main_array=[] for i in range (0,n): inp=input() array=(inp.split(" ")) main
