writing data from a python list to csv row-wise

Question

Using python, i am writing data from a list to a .csv file, row-wise.

Code:

writer=csv.writer(open(filepath,'wb'))
header=['type','id','numberOfUpdates','isPingEnabled','lastUpdated']
length_list=len(header)
i=0

while i!=length_list :
    data=header[i]
    print data
    i=i+1
    writer.writerow(data)

Result: Data is being written to csv file but each letter is printed in each column.

For example: type is written as 't' in one column, 'y' in next column and so on. I need the whole word in one column. Can some one point out what change can i make?

Thanks

Answer 1

Change writer.writerow(data) to writer.writerow([data]).

.writerow takes an iterable and uses each element of that iterable for each column. If you use a list with only one element it will be placed in a single column.

You should also restructure your loop:

for word in header:
    writer.writerow([word])
