在csp python中将dictionary作为参数传递会产生不可破坏的类型：“dict”

Question

我在python中应用CSP时，将字典作为参数传递给python中的方法时遇到了问题

officerDomain = range(0, 2**scheduleDays-1)

solver = MinConflictsSolver()
problem = Problem(solver)

officers = []
officers.append({'name':'Ryan', 'rank':'3'})
officers.append({'name':'Mond', 'rank':'1'})
officers.append({'name':'Eric', 'rank':'3'})


for officer in officers:
    print(officer)
    problem.addVariable(officer, officerDomain)

将字典传递到列表中时，会给出错误不可损坏类型：“dict”

Answer 1

让我们读一下documentation：

addVariable(self, variable, domain)

Parameters: variable - Object representing a problem variable (type=hashable object)

所以你不能使用字典（在这种情况下是官员），因为它不易损坏。例如，尝试使用officer["name"]
