python - CSV remove field value wrap quotes -


i'm attempting write list csv, when wrapper quotes around field values:

number1,number2 "1234,2345" "1235.7890" "2345.5687"

using code:

with open('c:\\temp\\test.csv', 'wb') out_file: ... csv_writer = csv.writer(out_file, delimiter=',') ... csv_writer.writerow(('number1','number2')) ... f in mylist: ... csv_writer.writerow(f)

after further research, found can remove writing of quotes using:

quotechar='', quoting=csv.quote_none**

when apply code error:

traceback (most recent call last): file "", line 4, in error: need escape, no escapechar set

with open('c:\\temp\\test.csv', 'wb') out_file: ... csv_writer = csv.writer(out_file, delimiter=',',quotechar='', quoting=csv.quote_none) csv_writer.writerow(('number1','number2')) ... f in mylist: ... csv_writer.writerow(f)

how remove these quotes?

edit

mylist looks like:

 [['1234,2345'], ['1235,7890'], ['2345,5687']]

what's in list not numbers text, containing delimiter character. means export csv has escaped.

you need convert data numbers before export csv if want written correctly.

edit: on other hand data looks consits of comma separated values - why not write file directly without using csv writer?

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
