Thank you very much Johann.

i was using print(update wuery here) and i was seeing that print was able
to parser the query and that consused me as to why execute wont do the same
since with print all values was gettign substituted.

of course pymysql doesnt behave the same with print but until i fugure that
out cost me lots of time.
