Floating point comparison.

There is a better way to write this code:

for i in range(50, 56, 1):
        print(i / 10)
print("Half way done!")
for k in range(56, 61, 1):
     print(k / 10)
print("All the way done!")

Output:

5.0
5.1
5.2
5.3
5.4
5.5
Half way done!
5.6
5.7
5.8
5.9
6.0
All the way done!

I've been trying to compare floating point numbers and this is the best I have gotten so far, there are methods out there but I cant understand them as I'm not at that level yet, so if anyone could provide an alternative way of comparing floating point numbers, that would be much appreciated. Thanks!

Instead of trying to compare i/10 to 5.5, simply compare the loop iterator (which is an integer) to the calculated halfway point (another integer):

start = 50
end = 61
half = (end-start)//2 + start
for i in range(50, 61):
    print(i/10)
    if i == half:
        print('Half way done!')

print("All the way done!")
