Writing a string with comma in one column of CSV file

[Mahmood Naderan]

Hi,
I use the following line to write some information to a CSV file which is comma delimited.

f = open(output_file, 'w', newline='')
wr = csv.writer(f)
...
f.write(str(n) + "," + str(key) + "\n" )


Problem is that key is a string which may contain ',' and this causes the final CSV file to have more than 2 columns, while I want to write the whole key as a single column.

I know that wr.writerow([key]) writes the entire key in one column, but I would like to do the same with write(). Any idea to fix that?


Regards,
Mahmood
