Solve the following python programming problem given the following code:
@ mock_kms 
def test__list_aliases() : 
    region = 'eu-west-1' 
    kms = boto.kms.connect_to_region (region) 
    create_resp = kms.create_key () 
    key_id = create_resp ['KeyMetadata'] ['KeyId'] 
    kms.create_alias ('alias/my-alias1', key_id) 
    kms.create_alias ('alias/my-alias2', region) 
    kms.create_alias ('alias/my-alias3', key_id) 
    resp = kms.list_aliases () 
    resp ['Truncated'].should.be.false 
    aliases = resp ['Aliases'] 
    def has_correct_arn(alias_obj) : 
        alias_name = alias_obj ['AliasName'] 
        alias_arn = alias_obj ['AliasArn'] 
        return re.match ('arn:aws:kms:{region}:\\d{{12}}:{alias_name}'.format (region = region, alias_name = alias_name), alias_arn) 
len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/aws/ebs' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/aws/rds' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/aws/redshift' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/aws/s3' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/my-alias1' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (has_correct_arn (alias) and ('alias/my-alias2' == alias ['AliasName']))]).should.equal (1) 
    len ([alias for alias in aliases if (('TargetKeyId' in alias) and (key_id == alias ['TargetKeyId']))]).should.equal (3) 
    len (aliases).should.equal (7) 

    
    

    Fix the buggy line: kms.create_alias ('alias/my-alias2', region)

#Here is Python program to fix the buggy line: kms.

kms.create_alias ('alias/my-alias2', key_id)
