How do I do an F-test to check if the variance is equivalent in two vectors in Python?

For example if I have 

```
a = [1,2,1,2,1,2,1,2,1,2]
b = [1,3,-1,2,1,5,-1,6,-1,2]

```

is there something similar to 

```
scipy.stats.ttest_ind(a, b)

```

I found 

```
sp.stats.f(a, b)

```

But it appears to be something different to an F-test
