How to Export a Nested Python List to a CSV File?

Exporting a Nested Python List to a CSV File

Need a quick and efficient way to transform a Python list of lists into a CSV file? Dive right into this solution:

import csv

# Sample list of lists
a = [[1.2, 'abc', 3], [1.2, 'werew', 4], [1.4, 'qew', 2]]

# Open the output CSV file for writing
with open('out.csv', 'w', newline='') as f:

Next, leverage the csv module's writer function to do the heavy lifting:

    # Create a writer object
    writer = csv.writer(f)

    # Write the rows to the file
    writer.writerows(a)

And voila! Your nested list will be neatly written to the out.csv file in the desired format:

1.2,abc,3
1.2,werew,4
1.4,qew,2

Enjoy the power of Python and CSV for your data manipulation tasks!
