XML Stack Overflow

I am using dicttoxml module for converting dictionary into xml.

Code:

from dicttoxml import dicttoxml
xml = dicttoxml(self.cfg_dict)
print (xml)

Output:

b'<?xml version="1.0" encoding="UTF-8" ?><root><mobile type="dict"><checkBox_OS type="dict"><radioButton_Andriod type="dict"><status type="bool">false</status><comboBox_Andriod_Brands type="str">Sony</comboBox_Andriod_Brands></radioButton_Andriod><radioButton_Windows type="dict"><status type="bool">false</status><comboBox_Windows_Brands type="str">HTC</comboBox_Windows_Brands></radioButton_Windows><status type="bool">false</status><radioButton_Others type="dict"><status type="bool">false</status><comboBox_Others_Brands type="str">Apple</comboBox_Others_Brands></radioButton_Others></checkBox_OS><checkBox_Screen_size type="dict"><doubleSpinBox_Screen_size type="float">5.0</doubleSpinBox_Screen_size><status type="bool">false</status></checkBox_Screen_size></mobile></root>'

I do not know why it is enclosed with b' '. How to generate xml string without this b''?

Browser is also giving error msg when opening xml file with this content.
