How to Write a Python List of Lists to a CSV File
Have a complex list of lists in Python? Need to export it to a clean, comma-separated values (CSV) file? Here's how:
Python's built-in csv module simplifies this task:
import csv
with open('out.csv', 'w', newline='') as f:
writer = csv.writer(f)
writer.writerows(a)This code assumes your list is named a. The csv.writer() function handles the conversion, while newline='' ensures no extra line breaks are added.
To customize the output format, explore the optional parameters available in csv.writer(). With this approach, you can effortlessly transform your Python data into a well-structured CSV file.
