import csv

#------ We will write to CSV in this function ------------

def csv_writer(data, path):
    
    #Open CSV file whose path we passed.
    with open(path, "wb") as csv_file:
        
        writer = csv.writer(csv_file, delimiter=',')
        for line in data:
            writer.writerow(line)



#---- Define our list here, and call function ------------

if __name__ == "__main__":

    """
    data = our list that we want to write. 
    Split it so we get a list of lists.
    """
    data = ["first_name,last_name,age".split(","),
            "John,Doe,22".split(","),
            "Jane,Doe,31".split(","),
            "Jack,Reacher,27".split(",")
            ]
