I have the following in my code:

y.append(float(row[-1]))

I keep getting this error:

ValueError: could not convert string to float: 'finish_pos'

I am relatively new to Python. Can anyone explain this or help me? Thanks

I strongly feel that you have a non numeric string like `a2.d3` this is not an convertable string – Panna Das Dec 11 '17 at 06:22
thanks. Is there a way I can check for this? I have many lines in my file. – Matt Dec 11 '17 at 06:24
you can use to check this link https://www.pythoncentral.io/how-to-check-if-a-string-is-a-number-in-python-including-unicode/ – Panna Das Dec 11 '17 at 06:26
thank you, I did indeed have a non numeric string. – Matt Feb 05 '18 at 22:59
