TypeError: list indices must be integers, not float

Question

I have a python 3.x program that is producing an error:

def main():
    names = [\'Ava Fischer\', \'Bob White\', \'Chris Rich\', \'Danielle Porter\',
                    


        

Answer 1

I had this problem when using ANN and PyBrain on function testOnData().

So, I solved this problem putting "//" instead "/" inside the index on backprop.py source code.

I changed:

print(('Max error:', 
    max(ponderatedErrors), 
    'Median error:',
     sorted(ponderatedErrors)[len(errors) / 2])) # <-- Error area 

To:

print(('Max error:', 
    max(ponderatedErrors), 
    'Median error:',
     sorted(ponderatedErrors)[len(errors) // 2])) # <-- SOLVED. Truncated

I hope it will help you.
