tsv

Suppose that I have the following array of json objects, I want to convert them to the tsv format. [ { "x": "1", "y": "2", "z": "3" }, { "x": "6", "y": "7", "z": "B" } ] Does anyone have a good solution to this? (python's json module only allow reading json object, but how to read an array of json object?) x<TAB>y<TAB>z 1<TAB>2<TAB>3 6<TAB>7<TAB>8 The first step is to convert from a JSON string to an array of Python objects using, for example, json.loads . The final step is to write the Python objects to a file using, for example, csv.DictWriter . Here is a complete program that demonstrates

How can I specify blank/empty value for a text field when using the robotframework-seleniumlibrary with a TSV file? For example, I have the following: Textfield Value Should Be identifier=name1 Chris Textfield Value Should Be identifier=name2 I want to test that name2 is blank. I have tried leaving it blank (which returns a message about an incorrect number of arguments. I have tried "", which looks for a pair of quotes, and '' which enters a single quote, and selenium seems to look for that janne You can use either a single backslash \ or special variable ${EMPTY} to create an empty string in

I'm trying to import a (rather large) .txt file into a table geonames in PostgreSQL 9.1. I'm in the /~ directory of my server, with a file named US.txt placed in that directory. I set the search_path variable to geochat, the name of the database I'm working in. I then enter this query: COPY geonames FROM 'US.txt', DELIMITER E'\t', NULL 'NULL'); I then receive this error: ERROR: could not open file "US.txt" for reading: No such file or directory. Do I have to type in \i US.txt or something similar first, or should it just get it from the present working directory? Erwin Brandstetter A couple of

I have a TSV file, that looks like this: A B C D D=1;E=2 S D F G H=2;B=4 I'd like to write the contents to another tsv file in this way. A B C D D 1 A B C D E 2 S D F G H 2 S D F G B 4 I'd really appreciate if anyone could help/ hint me in splitting column 5 as desired. If you are positively sure you only have tabs and semicolons, then you can use split. with open('/tmp/test.tsv') as infile, open('/tmp/test2.tsv', 'w') as outfile: for line in infile: tsplit = line.split("\t") firstcolumns = tsplit[:-1] lastitems = tsplit[-1].strip().split(";") for item in lastitems: allcolumns = firstcolumns +

I am trying to read a .tsv (tab-separated value) file into R using a specific encoding. It's supposedly windows-1252 . And it has a header. Any suggestions for the code to put it into a data frame? Something like this perhaps? mydf <- read.table('thefile.txt', header=TRUE, sep="\t", fileEncoding="windows-1252") str(mydf) Frederica Stahl You can also use: read.delim('thefile.txt', header= T, fileEncoding= "windows-1252") Simply entering the command into your R consol: > read.delim function (file, header = TRUE, sep = "\t", quote = "\"", dec = ".", fill = TRUE, comment.char = "", ...) read.table

Trying to convert a .tsv to a .csv. This: import csv # read tab-delimited file with open('DataS1_interactome.tsv','rb') as fin: cr = csv.reader(fin, delimiter='\t') filecontents = [line for line in cr] # write comma-delimited file (comma is the default delimiter) with open('interactome.csv','wb') as fou: cw = csv.writer(fou, quotechar='', quoting=csv.QUOTE_NONE) cw.writerows(filecontents) Gives me this error: File "tsv2csv.py", line 11, in <module> cw.writerows(filecontents) _csv.Error: need to escape, but no escapechar set While attempting to write to the CSV file, it encounters a token where
