Convert a lists in list to a CSV file by Python -


i hope convert data [[2,3,1],[11,2,4],[8,9,14]] csv file , format (numbers in each line in different columns)

line1: 2  3  1 line2: 11 2  4 line3: 8  9  14

however, when use following codes (list name of list should converted):

myfile = open('/users/user/desktop/list245.csv', 'wb') wr = csv.writer(myfile, quoting=csv.quote_all) wr.writerow(list)

the result is:

line 1: [2,3,1],[11,2,4],[8,9,14]. namely, every numbers in first line different groups.

you need convert list of list list first.

from itertools import chain row = list(chain.from_iterable([[2,3,1],[11,2,4],[8,9,14]]))

then can write csv file

with open('/users/user/desktop/list245.csv', 'w') myfile:     wr = csv.writer(myfile, quoting=csv.quote_all)     wr.writerow(row)
