python实现的小例子：
问题：如故一个运输任务是跑102英里，运输了6次，预计多少小时？
from numpy import genfromtxt
from sklearn import linear_model
dataPath = r"Delivery.csv"
deliveryData = genfromtxt(dataPath,delimiter=',')
print ("data")
print (deliveryData)
x= deliveryData[:,:-1]
y = deliveryData[:,-1]
print (x)
print (y)
lr = linear_model.LinearRegression()
lr.fit(x, y)
print (lr)
print("coefficients:")
print (lr.coef_)
print("intercept:")
print (lr.intercept_)
xPredict = [[102,6],[103,7]]
yPredict = lr.predict(xPredict)
print("predict:")
print (yPredict)
Delivery.csv文件内容为：
结果：
