How do I do a F-test in python

Question

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

For anyone who came here searching for an ANOVA F-test or to compare between models for feature selection

• sklearn.feature_selection.f_classif does ANOVA tests, and
• sklearn.feature_selection.f_regression does sequential testing of regressions
