trying to write a dictionary in a csv file

[Larz60+]

I would save the dictionary to a json file.

The example below includes a test routine and dictionary display routine which you don't need for your app.

import csv
import os
import json


filename = 'rankedhands.json'

def save_rankedhands():
    # Make sure cwd same as script
    os.chdir(os.path.abspath(os.path.dirname(__file__)))

    fields = ['Rank','Hands']

    straightlist = {
        1: [['10', 'X'], ['11', 'X'], ['12', 'X'], ['13', 'X'], ['14', 'X']],
        2: [['9', 'X'], ['10', 'X'], ['11', 'X'], ['12', 'X'], ['13', 'X']],
        3: [['8', 'X'], ['9', 'X'], ['10', 'X'], ['11', 'X'], ['12', 'X']],
        4: [['7', 'X'], ['8', 'X'], ['9', 'X'], ['10', 'X'], ['11', 'X']],
        5: [['6', 'X'], ['7', 'X'], ['8', 'X'], ['9', 'X'], ['10', 'X']],
        6: [['5', 'X'], ['6', 'X'], ['7', 'X'], ['8', 'X'], ['9', 'X']],
        7: [['4', 'X'], ['5', 'X'], ['6', 'X'], ['7', 'X'], ['8', 'X']],
        8: [['3', 'X'], ['4', 'X'], ['5', 'X'], ['6', 'X'], ['7', 'X']],
        9: [['2', 'X'], ['3', 'X'], ['4', 'X'], ['5', 'X'], ['6', 'X']]
    }

    with open(filename, 'w') as jfile:
        json.dump(straightlist, jfile)

def display_dict(dictname, level=0):
    indent = " " * (4 * level)
    for key, value in dictname.items():
        if isinstance(value, dict):
            print(f'\n{indent}{key}')
            level += 1
            display_dict(value, level)
        else:
            print(f'{indent}{key}: {value}')
        if level > 0:
            level -= 1

def test_save_rankedhands():
    # Save dictionary to json file
    save_rankedhands()

    # read json file into newdict and display
    with open(filename) as jfile:
        newdict = json.load(jfile)

    display_dict(newdict)


if __name__ == '__main__':
    test_save_rankedhands()

Test results:

Output:
1: [['10', 'X'], ['11', 'X'], ['12', 'X'], ['13', 'X'], ['14', 'X']]
2: [['9', 'X'], ['10', 'X'], ['11', 'X'], ['12', 'X'], ['13', 'X']]
3: [['8', 'X'], ['9', 'X'], ['10', 'X'], ['11', 'X'], ['12', 'X']]
4: [['7', 'X'], ['8', 'X'], ['9', 'X'], ['10', 'X'], ['11', 'X']]
5: [['6', 'X'], ['7', 'X'], ['8', 'X'], ['9', 'X'], ['10', 'X']]
6: [['5', 'X'], ['6', 'X'], ['7', 'X'], ['8', 'X'], ['9', 'X']]
7: [['4', 'X'], ['5', 'X'], ['6', 'X'], ['7', 'X'], ['8', 'X']]
8: [['3', 'X'], ['4', 'X'], ['5', 'X'], ['6', 'X'], ['7', 'X']]
9: [['2', 'X'], ['3', 'X'], ['4', 'X'], ['5', 'X'], ['6', 'X']]
