Typeerror: 'nonetype' Object Is Not Subscriptable

The error: names = curfetchone()[0] TypeError: 'NoneType' object is not subscriptable. I tried checking the indentation but still there's an error. I read that maybe the variable

Solution 1:

If, due to whatever reason (empty result set?) curfetchone() returns None, a [0] access is of course forbidden (as the error message clearly says).

So better do that in two steps and do

row = curfetchone()
if row isnotNone: 
    names = row[0]
    # proceedelse:
    # act appropriately
