问题 I am running the FPGrowth algorithm using pyspark in python3.6 using jupyter notebook. When I am trying to save the association rules output of rules generated is huge. So I want to limit the number of consequent. Here is the code which I have tried. I also changed the spark context parameters.

问题 This question already has answers here : Items in JSON object are out of order using “json.dumps”? (6 answers) Closed last year . I need to generate a MD5 Hash in Python 3 to compare with a MD5 Hash that was generated on Python 2, but the result for json.dumps() is different, because on Python 2 the position of the elements changes and the MD5 result is different. How can I generate the same result? The code: content = {'name': 'Marcelo', 'age': 30, 'address': {'country': 'Brasil'},

问题 This question already has an answer here : How does the asyncio module work, why is my updated sample running synchronously? (1 answer) Closed last year . I have written a basic REST API using aiohttp, a simplified version of which is included below to illustrate the problem I am looking to solve. The API has two endpoints - each of which calls a function that performs some calculations. The difference between the two is that for one of the endpoints, the calculations take 10 seconds, and for

问题 Or, perhaps a better title: how to avoid unwanted extra carriage return when passing binary file to text mode write clause. Python 3.6, Windows. Input file needs to undergo first a binary search/replace, and then a regex search/replace. I first open the input file in binary mode, do the work, and save it in binary mode in a temporary file. Then I open that in text mode, do the regex search/replace, and save it in text mode (with a name resembling that of the input file). def fixbin(infile):

问题 I am trying to run multiple commands using paramiko. Channel.recv raises paramiko.buffered_pipe.PipeTimeout exactly after reading 9999 lines from server. I am connecting to remote Windows server 2012 with openssh installed from linux. Output from windows server has ANSI sequences and H code, so I could see Channel.recv waits for timeout after reading 9999 lines. Channel.recv(buffer_size) waits for timeout after this output b'\x1b[9999;54H' (9999 line, 54 column). Here is my minimal

问题 I've installed openpyxl from the Terminal using pip3 install openpyxl without any problems. I've even double-checked by simply running import openpyxl from the Terminal window once Python is running, and it imports no problem. The problem starts when I try and import openpyxl from a script I'm building to work with a spreadsheet. I'm using Sublime Text and can't even get past the import openpyxl at the beginning of the script without running into the following error: Traceback (most recent
