Mysql Python Connector: "not All Arguments Converted During Bytes Formatting"

I have a mysql database in which 'user' table having f_name,l_name,password email(pk) by which session is created and table 'friendgroup' having fg_name(pk), email((pk),users.email

Solution 1:

A common error in python is to use (bar) instead of (bar,) the former not being a tuple.

Try with:

cursor.execute(find_owned_friendgroups, (user,))
