quoting

I have a .text file with following format, where fields (index number, name and message) are separated by \t (tab-separated): 712 ben Battle of the Books 713 james i used to be in TOM 714 tomy i was in BOB once 715 ben Tournaments of Minds 716 tommy Also the Lion in the upcoming school play 717 tommy Can you guess 718 tommy P ... which I read with read_csv into a data frame: chat = pd.read_csv("f.text", sep = "\t", header = None, usecols = [2]) But the data frame just has 9812 rows while the ordinary file has more than 12428 rows (just 21 empty lines). It is quite weird. Do you have any idea?

I'm writing a utility (which happens to be in python) which is generating output in the form of a TCL script. Given some arbitrary string variable (not unicode) in the python, I want to produce a TCL line like set s something ... which will set TCL variable ' s ' to that exact string, regardless of what strange characters are in it. Without getting too weird, I don't want to make the output messier than needed. I believe a decent approach is if the string is not empty and contains only alphanumerics, and some characters like .-_ (but definitely not $"{}\ ) then it can be used as-is; if it

I'm having a hard time understanding (and therefore remembering) the clojure require syntax described here: http://clojuredocs.org/clojure_core/1.3.0/clojure.core/require . It seems both counter intuitive and non-uniform. For example, in the following why is this vector required to be quoted: (require '[clj-json.core :as json]) Counter intuitive because normally vectors are not quoted in clojure (lists are quoted and vectors are treated as data). And non-uniform because in this case the vector is NOT quoted: (ns xxx (:require [clj-json.core :as json])) I realize that the require function and

This question already has an answer here: Running shell command that has nested quotes via ssh 3 answers Double quotes inside quotes in bash 2 answers Escaping quotes when using SSH 2 answers My need is to make this command work: sshpass -p XXXX ssh -oStrictHostKeyChecking=no wsuser@192.168.0.100 sudo docker exec -u postgres postgres-container /bin/bash -c \" psql -d crawl-configuration -c 'select * from schema_version'\" But the result indicates that * is expanded by the shell and all matching files are passed as arguments to the psql command. So I searched how to protect the command from

I have a CSV file, but unlike in related questions, it has some columns containing double-quoted strings with commas, e.g. foo,bar,baz,quux 11,"first line, second column",13.0,6 210,"second column of second line",23.1,5 (of course it's longer, and the number of quoted commas is not necessarily one or 0, nor is the text predictable.) The text might also have (escaped) double-quotes within double-quotes, or not have double-quotes altogether for a typically-quoted field. The only assumption we can make is that there are no quoted newlines, so we can split lines trivially using \n . Now, I'd like
