Is there a t test in a python package where you can test for difference? If there is how do you use it?

For example test two vectors:

a=np.random.randn(5, 7)
b=np.random.randn(5, 7)

I have found the t test : ttest_ind in statsmodels. However I would like to specify the difference to test for, this can not be passed into the ttest_ind function. Does anybody know another way to do this?

ttest_ind in statsmodels has a value option, to test the null hypothesis that the difference between the two means is equal to value
