Re: TypeError: can't concat bytes to tuple

Well, this is not a Django-related question, but still.

The tutorial you are following uses Python 2.5.1, which differs a lot from the Python 3.4 that you are using. If you want to still follow that tutorial you'd better install Python 2.7, which is more compatible with 2.5

Also, try printing the query (the sql variable in your case) before executing it in mysql and check if it is right (in particular that it is actually a string and not a list, tuple, or something else)

Regards!

on Centos 6.4 , Python 3.4 but not sure why it is failing with below exception :

TypeError: can't concat bytes to tuple

Anyone has any idea about this ? Also , how can we make sure to prevent from Identation erros in python ?

Thanks
