Question

I\'m trying to write a csv file using python csv writer.

In which one of the column value is enclosed in \"\" [double quotes] e.g. : \'col1\' \'col2\' \"test\", when

Answer 1

Probably you need to play with parameters quoting and escapechar.

For example, modified code

csvReader = csv.reader(iInputFile)
writer = csv.writer(open('one_1.csv', 'wb'), delimiter=',', lineterminator='\r\n', quoting=csv.QUOTE_NONE, escapechar='\\')

for row in csvReader:
     rawRow = []
     rawRow.append('31-7-2014') #Appending Date
     rawRow.append(row[0])   #Appending data
     rawRow.append('\"'+'test'+'\"') 
     writer.writerow(rawRow)

will produce output like that:

31-7-2014,'col1',\"test\"

Answer 2

As far as I can tell from the accepted answer from @GiovanniPi, is that the default is

quotechar= '"'

Because the expected output already has double quotes, this has to be changed to:

quotechar = "'"

I am not sure what you would do if you needed to have both single and double quotes as quotechar requires a 1-character string

Answer 3

try with this one

f_writ = open('one_4.csv', 'wb')
csvReader = csv.reader(iInputFile)
writer = csv.writer(f_writ, delimiter=',',
                lineterminator='\r\n',
                quotechar = "'"
                )

for row in csvReader:

    writer.writerow(['31-7-2014',row[0],'\"text\"'])

f_writ.close()
