<__ main __。CloudTravel对象位于0x000000D30F609828>不可迭代

Question

.py

a = (0,0,70)
b = (90,0,45)
c = ("1 2","0 2","0 1")
d = 0
e = 1

class Travel(object):

    def trip(self,latitude,longitude,canTravel,origin,destination):
        self.latitude    = latitude
        self.longitude   = longitude
        self.canTravel   = canTravel
        self.origin      = origin
        self.destination = destination
        print(latitude)
        print(longitude)
        print(origin)
        print(destination)
        print(canTravel)
        for c in canTravel:
            print(c)
        pass


c = Travel()
c.trip(a,b,c,d,e)

输出

(0, 0, 70)
(90, 0, 45)
0
1

TypeError: 'Travel' object is not iterable

我想将字符串（“ 1 2”，“ 0 2”，“ 0 1”）的元组传递给跳闸函数，并希望对其进行迭代。

如何遍历<< strong> main 。旅行对象位于0x000000E836D25898>
