How do I remove the commas, quotes, and parentheses from an exported python list?

export, python, python-3.x

Solution

Your question:

I recommend that you just use the `join` method to get the single string you are looking for. You could try:

with open('test.csv', 'w') as a_file:
    for result in C:
        result = ' '.join(result)
        a_file.write(result + '\n')

Basically, the `join` method called on a the string `' '` (a single space) will take each item in its argument (a single result from your permutations) and add them together in a single string separated by whatever that first string was (the single space). This site gives a simple, illustrative example.

The `join` method is called with the syntax `'[separator]'.join([list of items to join])`, so if you just wanted to mash everything together into one string with no spaces, you could call it on an empty string: `''.join([my list])`.

Since you do not need a comma-separated file (CSV), you can simplify things by just using the `a_file.write` method as shown. If you use the CSV writer in this code you will get commas between every letter.

Problem

You guys were super helpful with my last newbie question so I figured I would give it another shot. Right now, my Python 3 code takes data from a CSV file, stores the data as a list, creates permutations of that data, and exports it back out into a new csv file in a column format. Unfortunately, the format of the exported list is not the best for what I need it for. My question is: How do I remove the commas, brackets, and parenthesis from the exported list in python? How it Looks Now: ('Hello', 'World', 'How') ('Hello', 'World', 'Are') ('Hello', 'How', 'World') How I would like it to look: Hello World How Hello World Are Hello How World Here is the code I am using, does anyone have any advice or suggestions? I am trying to learn so any extra insight would be much appreciated! ``` import csv import itertools with open('/users/Desktop/pythondata.csv', 'r') as f: reader = csv.reader(f) J = [] for row in reader: J.extend(row) C = list(itertools.permutations(J, 3)) with open('THISISATEST.csv','w')as f: writer=csv.writer(f,lineterminator='\n') for val in C: writer.writerow([val])` ``` P.S. -- Please forgive me if this is not formatted correctly, I am new to the board!
