Question

我是Python新手。我收到一个错误，上面写着“未定义的变量”。我无法理解。代码中的陈述如下：

Classroom1 = Classroom(FirstCourseStartTime = 8, LastCourseEndTime = 7.75)
m_count = 0 
h_count = 0
t_count = 0
l_count = 0
loopsize = 10000
Loop(Classroom1, m_count, h_count, t_count, l_count, loopsize)
def Loop(Classroom1, m_count, h_count, t_count, l_count, loopsize):
    for i in range(0, loopsize):
        Mutated = Classroom()
        Mutated = Classroom1.CopyOfClassroom(Mutated)
        Mutated.Mutate()
        HardConstraintClassroomMet = Classroom1.ComputeHardConstraint()
        HardConstraintMutatedMet = Mutated.ComputeHardConstraint()
        if HardConstraintClassroomMet == False and HardConstraintMutatedMet == False:
            h_count + 1
            t_count + 1
            Classroom1.Mutate()
            continue
        if Mutated.FitnessValue() > Classroom1.FitnessValue():
            m_count + 1
            t_count + 1
            Classroom1 = Mutated
        if Classroom1.ComputeHardConstraint() == False:
            l_count + 1
            temp = l_count*loopsize
            print "Unable to meet hard consraints in %d" % temp
        Loop(Classroom1, m_count, h_count, t_count, l_count, loopsize)

Answer 1

在定义之前，您正在调用Loop()函数。

Answer 2

首先你需要组织：

class classroom,
    def loop

在函数循环中写入globals：

global m_count
global h_count
global t_count

最后更改if语句：

if HardConstraintClassroomMet == False and HardConstraintMutatedMet == False:
        h_count = h_count + 1
        t_count = t_count + 1

未定义的变量循环
