export-to-csv

问题 I am parsing a large piece of text into dictionaries, with the end objective of creating a CSV file with the keys as column headers. csv.DictWriter(csvfile, fieldnames, restval='', extrasaction='raise', dialect='excel', *args, **kwds) The problem arises as the dict for any 'n'th row can include a new, never before used key. I then want the CSV to contain a column for this new key as well. In short, all my fields are not known beforehand so I cannot compile a complete fieldnames at the

问题 I have a script that scans all my servers in my domains and outputs to two separate CSV files - one simple and one extensive. I write one line at the time to my csv.. This results in thousands of file-open and file-close.. I've lurked around and understand that I should first gather all the info and write it all in one sweep at the end of the script. But how do I do this with export-csv (preferably using a function)? And is there a way I can use the same function for short and long list? The

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I am trying to convert a dynamic XML to CSV. I searched for various options to achieve this but did not find a suitable answer. The structure of the XML is dynamic - It can be a product data, a geography data or any such thing. So, I am not able to use predefined XSL or castor conversion. The tag names should

问题 Is it possible to easily export whole index (all stored fields) of an elasticsearch cluster in a .csv file(possibly out of the box)? The alternative I can think is query the whole index and then convert the result... but I really don't like the idea of parsing a monstrous json since it contains some millions of documents! Are there any other ways or ideas to achieve the export? 回答1: Disclaimer: I'm the author of estab. estab exports elasticsearch fields as tab separated values. If you do not

问题 Below, is the json structure I am pulling from my online weather station. I am also including a json_to_csv python script that is supposed to convert json data to csv output, but only returns a "Key" error. I want to pull data from "current_observation": only. { "response": { "features": { "conditions": 1 } } , "current_observation": { "display_location": { "latitude":"40.466442", "longitude":"-85.362709", "elevation":"280.4" }, "observation_time_rfc822":"Fri, 26 Jan 2018 09:40:16 -0500",

问题 I need to combine a slew of Excel spreadsheets. I used PowerSHell to convert them to CSVs and now need to merge them, but not as you typically would. The merge doesn't use a join. If I have 3 files with 100 rows each, my new file should have 300 rows. So, this is more if a UNION than a JOIN to use database terms. Some of the columns do have the same name. Some don't. If they have the same name, a new column shouldn't be created. Is there a way to do this without manually having to list out

问题 I have an issue with some XML files. I cannot say a lot about data, because it is for work and I don't want to be in trouble! From a huge XML file, 123091 lines of code, I only need data from 7 tags(if that makes sense). I am trying to extract that specific data, but I am having a bit of a situation when trying to store into pandas or csv. I have found a method to take some information out, like: for info in root.iter('ArtistName'): print(info.text) The code above will give me the artists in

问题 I need help getting started on this script and will do the best to explain what I am trying to accomplish. I have a set of clusters, some have no custom config, some have one custom config, some have two, and other have more. I would to export these custom configs into a CSV, with column headers like custom1, custom2, custom3, etc. So I need the script to create new column headers based on how many custom config a cluster might have, while either adding NULL or leaving blank cluster that don
