How to perform two-sample one-tailed t-test with numpy/scipy

Question

In R, it is possible to perform two-sample one-tailed t-test simply by using

> A = c(0.19826790, 1.36836629, 1.37950911, 1.46951540, 1.481977

Did you look at this: How to calculate the statistics "t-test" with numpy

I think that is exactly what this questions is looking at.

Basically:

import scipy.stats
x = [1,2,3,4]
scipy.stats.ttest_1samp(x, 0)

Ttest_1sampResult(statistic=3.872983346207417, pvalue=0.030466291662170977)

is the same result as this example in R. https://stats.stackexchange.com/questions/51242/statistical-difference-from-zero
