NameError: name 'csv' is not defined

Question

I am new to Python, and I want to write a csv file, that lists the roots of my equation. I am working on Sage. My code is :

with open('out.csv', 'w') as f:
    c = csv.writer(f)
    c.writerows(root)

The error I am getting is " NameError: name 'csv' is not defined "

Can anybody help please?

Answer 1

csv is not a builtin, although it's part of the standard library. You need to import it:

import csv

# your code
