Python Question

Please see image below for my references.

The first column just gives us the row numbers

2nd column is the Fibonacci sequence, just adding the previous 2 to get the new row

3rd column should be the quotient of last row b divided by previous a value

It works up until the 4th iteration where the fraction should be:

1.6, but it is 1.0000000 from then on

3rd col should be

`0`

1

2

1.66666666667

1.6

1.625 etc etc.

But it is doing

`0`

1

2

1.0000

1.0000

1.0000

1.0000 etc.

What is wrong with my code? It should work but isn't. Here is python 3 code:

`a, b = 0, 1`

num = 1

i = 1

f= 0

#loop

for i in range(1, 101):

#use if to avoid divide by zero initially because a is 0

if a >= 1:

f = b / a

#print 3 column of 3 different numbers

print ('{0:4d} {1:20d} {2:1.14f}'.format(i, b, f) )

i = i + 1

a,b = b, a+b

Answer

If you're using Python 2, change the line:

```
f = b / a
```

into

```
f = float(b) / float(a)
```

Are you sure you're using Python 3? What does `python -V`

report?
