Executing Dynamic SQL using Python but receiving exceptions

I have below dynamic SQL script which runs on SQL Server with no issues.

DECLARE 
@file_type_id int = 1,
@filing_id bigint = 57,
@created_at datetime = GETDATE(),
@created_by bigint = 2,
@is_required bit = 1,
@insertquery nvarchar(MAX),
@Filepath nvarchar(MAX) = 'C:\SampleTestFiles\MyWordDoc.doc';

SET @insertquery = 
'DECLARE @Document AS VARBINARY(MAX);
 SELECT @Document = CAST(bulkcolumn AS VARBINARY(MAX)) FROM OPENROWSET( BULK ' + QUOTENAME(@filepath,'''') +', SINGLE_BLOB ) AS Doc; 
 INSERT INTO [TEST].[dbo].[MyTable]  ( [file_type_id], [file],  [file_name], [filing_id], [created_at], [created_by], [is_required])
 VALUES (@file_type_id, @Document, @file_name, @filing_id , @created_at, @created_by, @is_required);';

EXEC sp_executesql 
@insertquery, 
N'@file_name varchar(100),@file_type_id int,@filing_id bigint,@created_at datetime, @created_by bigint,@is_required bit',
@file_name, @file_type_id, @filing_id, @created_at, @created_by, @is_required;

I am trying to execute the same SQL using Python but it doesn't runs and gives lot of syntax errors in Python IDE. Please can someone help me in correcting the Python code.

filepath = 'C:\SampleTestFiles\MyWordDoc.doc'
file_type_id = 1
file_name = 'test'
filing_id = 57
created_at = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
created_by = 1
is_required = 1

Query = '''
SET @insertquery = 
DECLARE @Document AS VARBINARY(MAX);
SELECT @Document = CAST(bulkcolumn AS VARBINARY(MAX)) FROM OPENROWSET( BULK \' + QUOTENAME(?,\'\'\'\') +\', SINGLE_BLOB) AS Doc;
INSERT INTO[TEST].[dbo].[MyTable]([file_type_id], [file], [file_name], [filing_id], [created_at], [created_by], [is_required])
VALUES(?,@Document, ?, ?, ?, ?, ?)
        '''
values = (filepath, file_type_id, file_name, filing_id, created_at, created_by, is_required)

# Execute SQL Insert Query
cursor = conn.cursor()
cursor.execute(Query, values)
cursor.close()
conn.commit()
print("File inserted..")
