we use python 3.5 in the test. And it seems it does not support format strings:

 Compiling './addons/test/test-cppcheckdata.py'...
***   File "./addons/test/test-cppcheckdata.py", line 37
    print(f'{token.str} : {token.valueType}')
                                           ^
SyntaxError: invalid syntax
