# This action requires the 'csv' module
import csv

# The basic usage is to first define the rows of the csv file:
row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]

# And then use the following to create the csv file:
with open('protagonist.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(row_list)
# This will create a csv file in the current directory

write to specific line in file python csv

# YOU CAN NOT CHOOSE WHAT ROW TO WRITE TO WHEN WRITING A ROW TO A CSV
# FILE WITH THE PYTHON CSV MODULE
# INSTEAD, YOU MUST WRITE ROWS IN CHRONOLOGICAL ORDER:
# EXAMPLE:
import csv

with open('file.csv', 'w') as f:
  writer = csv.writer(f)
  header = ['year','month','day'] # first row
  blank_row = ['n'] # second row (blank row)
  row1 = ['2020','Jul','23'] # 3rd row
  
  writer.writerow(header) # write the first row
  writer.writerow(blank_row) # write the blank row to skip a line
  writer.writerow(row1) # write the third row
