csv

问题 I need to write a pandas.Series object to a CSV file as a row, not as a column. Simply doing the_series.to_csv( 'file.csv' ) gives me a file like this: record_id,2013-02-07 column_a,7.0 column_b,5.0 column_c,6.0 What I need instead is this: record_id,column_a,column_b,column_c 2013-02-07,7.0,5.0,6.0 This needs to work with pandas 0.10, so using the_series.to_frame().transpose() is not an option. Is there a simple way to either transpose the Series, or otherwise get it written as a row? Thanks

问题 I'm using NetworkX to calculate 4 separate centrality metrics for a large network and now I would like to write the results to a CSV file. I don't want to write a single CSV file for each of the 4 metrics, but would rather have something like below: Id, degree, between, close, eigen 1, 0.4, 0.0, 0.5, 0.45 2, 0.4, 0.0, 0.5, 0.45 3, 0.6, 0.6, 0.71, 0.58 4, 0.6, 0.7, 0.71, 0.47 5, 0.2, 0.0, 0.45, 0.18 6, 0.2, 0.0, 0.45, 0.18 Below is the my code to show what I've done so far: import networkx as

问题 I am trying to programmatically capture a stream of packets by using Tshark . The simplified terminal command I am using is: tshark -i 2 -w output.pcap This is pretty straightforward, but I then need to get a .csv file in order to easily analyze the information captured. By opening the .pcap file in Wireshark and exporting it in .csv what I get is a file structured as follows: "No.","Time","Source","Destination","Protocol","Length","Info" but,again, I need to do this in an automatic way. So I

问题 I'm working on Laravel (v5.7) app that converts uploaded CSV (with contacts) into array that is then passed as argument when job class is being dispatched. Here is the example of CSV file (format that is supported): 123456,Richard,Smith 654321,John,Doe Uploaded (CSV) file is handled like this: $file_path = $request->file_name->store('contacts'); $file = storage_path('app/' . $file_path); $contactsIterator = $this->getContacts($file); $contacts = iterator_to_array($contactsIterator); // Array
