根据docs

from scipy.stats import linregress

a = [10, 25, 30]

b = [13720000, 9090000, 3900000]

lr = linregress(a, b)

要查询结果:

print(lr)
print(lr.slope)

返回:

LinregressResult(slope=-448923.0769230769, intercept=18630000.0, rvalue=-0.9511220069021482, pvalue=0.1998650358314477, stderr=145758.73719079647)
