it should still fix some issue , This works exactly how you want it :-
code :
    Global = 'none' 
    header = ['/', Global, 0]
    print ('[%s]' % ', '.join(map(str, header)).replace( "/","'/'"))

hope this fix your issue Currently all of the values in your list are strings, and you want them to integers, here are the two most straightforward ways to do this:
code :
map(int, your_list)
[int(value) for value in your_list]
print('[' + ', '.join(your_list) + ']')

To fix this issue To get int or float based on what each value looks like, so '1' becomes 1 and "1.2" becomes 1.2, you can use ast.literal_eval to convert the same way Python's literal parser does, so you have an actual list of ints and floats, rather than a list of str (that would include the quotes when echoed):
code :
>>> import ast
>>> [ast.literal_eval(x) for x in l]
[1, 2, 3, 4.5]
>>> print('[{}]'.format(', '.join(l)))
[1, 2, 3, 4.5]

I hope this helps . What is the best way to remove single quotes in a python list? , One solution is to use json.loads.
code :
import json

a_list = ['{"name": "Brian", "city": "Seattle"}', '{"name": "Rick", "city": "Boston"}']

dict_list = [json.loads(x) for x in a_list]

like below fixes the issue Steps:
Remove starting ^[' or | ending ']$ brackets. \ is for escaping, ^ for start of string, $ for end of string Turn empty lists [] into empty strings, again escaping with \ Remove empty strings Split by ', ' or ',' to seperate elements, ? means optional space
code :
from pyspark.sql import functions as f

data = [(("ID1", "['valA', 'valB']")), (("ID1", "[]")), (("ID1", "['valC']")), (("ID1", ""))]
df = spark.createDataFrame(data, ["ID", "colA"])

df_2 \
  .withColumn('colA_2', f.regexp_replace('colA', "^\['|'\]$", '')) \
  .withColumn('colA_2', f.regexp_replace('colA_2', "\[\]", '')) \
  .withColumn('colA_2', f.when(f.col('colA_2') == "", None).otherwise(f.col('colA_2'))) \
  .withColumn('colA_2', f.split('colA_2', "', ?'"))
df_2.show()

+---+----------------+------------+
| ID|            colA|      colA_2|
+---+----------------+------------+
|ID1|['valA', 'valB']|[valA, valB]|
|ID1|              []|        null|
|ID1|        ['valC']|      [valC]|
|ID1|                |        null|
+---+----------------+------------+
df_2.printSchema()

root
 |-- ID: string (nullable = true)
 |-- colA: string (nullable = true)
 |-- colA_2: array (nullable = true)
 |    |-- element: string (containsNull = true)
Extra quotes doing SQL insert from Perl to CSV. If I try to remove them, I get no quotes. I need single quotes as in &qu

like below fixes the issue to poj at PerlMonks (https://www.perlmonks.org/?node_id=11107315), there is a solution:
Here it is for everyone's convenience:
code :
#!/usr/bin/perl
use strict;
use DBI;

my $dbh = DBI->connect("dbi:CSV:", "", "",{
   'RaiseError' => 1 }
);  

$dbh->{'csv_tables'}->{'MyTable'} = {
 'file'         => 'data1.csv',
 'col_names'    => ["num","id"],
 'always_quote' => 1,
};

my $num = '0123';
my $id  = '0124';
my $sql = "INSERT INTO MyTable VALUES (?,?)";
my $sth = $dbh->do($sql,undef,$num,$id);
