You can find out by inserting a print line:
with open('/Users/richarddillon/Desktop/numbers.txt', 'r') as infile:
for line in infile:
print('Line = ', line)
total += float(line)
And see what the offending line looks like.
Once you know what the error is caused by you can add a line
or two to avoid (or handle) the problematic cases.
