python - 了解 Python/PuLP 代码的片段

Question

我必须采用他们使用 PuLP 包的现有脚本。我需要知道以下行的结果如何:

unit = ["one", "two", "three"]
time = range(10)

status=LpVariable.dicts("status",[(f,g) for f in unit for g in time],0,1,LpBinary)

键/值是什么样子的？

status["one"] = [0,1,1,1...]?

非常感谢您的帮助!

Answer 1

from pulp import *
unit = ["one", "two"]
time = range(2)

status=LpVariable.dicts("status",[(f,g) for f in unit for g in time],0,1,LpBinary)

导致

>>> status

{('two', 1): status_('two',_1), 
('two', 2): status_('two',_2), 
('one', 2): status_('one',_2), 
('one', 0): status_('one',_0), 
('one', 1): status_('one',_1), 
('two', 0): status_('two',_0)}

因此，不存在键为“one”的条目。
