How to Efficiently Write Line-by-Line Data to a CSV File?

Writing CSV Data Line by Line

Accessing comma-separated data via HTTP requests presents the challenge of saving it as a CSV file. By leveraging a StringIO object, you can iterate through the data line by line. However, how do you effectively write each line to CSV?

General Approach:

The conventional method to write a list of strings (each representing a line) to a CSV file is as follows:

text = ['line1', 'line2', ...]
with open('csvfile.csv', 'wb') as file:
    for line in text:
        file.write(line)
        file.write('\n')
Copy after login

CSV Writer:

For added flexibility, consider using the CSV writer module:

import csv
with open('path_to_output_csv', "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter=',')
    for line in data:
        writer.writerow(line)
Copy after login

Simplest Solution:

If simplicity is the priority, the following method directly writes text to a CSV file:

f = open('csvfile.csv', 'w')
f.write('hi there\n')  # Replace with your text
f.close()
Copy after login

Python will automatically convert line breaks to the appropriate format based on your operating system.
