python 3.x - 在tcolorbox中写入来自SQL查询的输出时不需要的字符

我正在使用python3，MariaDB，Jinja2和LaTeX + tcolorbox。我正在尝试在tcolour框内编写来自SQL查询的输出，但它在（''，）内部显示，如以下屏幕快照所示：

显示（'10 .0.38-MariaDB-0ubuntu0.16.04.1'，）

如何删除不需要的字符？谢谢。请查看下面包含的代码。

testdb.py

#!/usr/bin/python3
import jinja2
import os
import MySQLdb

connection = MySQLdb.connect("localhost","test","password")
cursor = connection.cursor()


# execute SQL query using execute() method.
cursor.execute("SELECT VERSION()")
# Fetch a single row using fetchone() method.
data = cursor.fetchone()
cursor.close()
connection.close()

from jinja2 import Template
latex_jinja_env = jinja2.Environment(
    block_start_string = '\BLOCK{',
    block_end_string = '}',
    variable_start_string = '\VAR{',
    variable_end_string = '}',
    comment_start_string = '\#{',
    comment_end_string = '}',
    line_statement_prefix = '%%',
    line_comment_prefix = '%#',
    trim_blocks = True,
    autoescape = False,
    loader = jinja2.FileSystemLoader(os.path.abspath('.'))
)

template = latex_jinja_env.get_template('tcsqltest.template')

print(template.render(section1="SQL query : %s " % data, data1=data, section2='SQL query shown inside tcolorbox example.'))
