Hi~I met the same problem, after read through the code I found it is due to the fact that the it is because in wikisql lib dbengine.py, when using "val = float(parse_decimal(val))" to convert the decimal string to decimal, they used babel package's parse_decimal method in default parameter of "locale"("locale" is what decide how to explain the number, for example if in "en", 197,168 means 197168, while in "de" German, it means 197.168), and the default locale is judeged by you utf-encode of the python file. So it may perform normal in mostly conditions, especially in US I think, but unnormally performed in some cases, which it set the locale to None, which cause the problem above "AttributeError: 'NoneType' object has no attribute 'number_symbols'", TL;DR, please change "val = float(parse_decimal(val))" to "val = float(parse_decimal(val, locale='en_US'))" , And I hope this be fixed or be pulled request to this wikisql code to make it perform well on all the devices.
