选择模型状态练习

根据下面的代码，选择模型状态将被打印为何值。

# Initialize Class, Define Decision Vars., Objective Function, and Constraints
from pulp import *
model = LpProblem("Exercise Routine", LpMaximize)
P = LpVariable('Pushups', lowBound=0)
R = LpVariable('Miles ran', lowBound=0)
model += 3 * P + 10 * R
model += P + R < 10
model += R > 11

# Solve Model
model.solve()
print("Status:", LpStatus[model.status])
