[Tutor] ValueError: could not convert string to float: '13,2'

[Keith Winston]

Hi PierreD, I think if you iterate over your strings with something like
this, it will do what you want, if I understand correctly (snum is your
string number, like "123,321"):

fnum = float(snum.replace(",", ".")

keith: rank beginner, take everything with a grain of salt!
