Answer 1

You're comparing strings.

Strings are compared by their first alphabets and 1 from 100.25 is less than 8 in 80.99.

You can fix this by converting all string numbers to floats:
a = list(map(float, a))

Answer 2

'80.99' > '100.25', because these are strings. If you want to compare them as floats you need to use an explicit cast:
a=str(input()).split(",")
print(a)
a = [float(x) for x in a]
b = max(a)
print(b)
