如果你在使用Python时遇到"object is not subscriptable"的错误提示，通常这意味着你试图对一个非可索引的对象进行索引操作。在给出的代码片段中，这个问题可能出现在尝试访问`eachInfoDict['MapID']`时，由于某些原因`eachInfoDict`可能不是一个字典，或者`MapID`键不存在于字典中。解决这个问题的关键...

map() doesn't return a list, it returns a map object.You need to call list(map) if you want it to be a list again.原文：http://stackoverflow.com/questions/6800481/python-map-object-is-not-subscriptable

1.Python报错:TypeError: 'type' object is not subscriptable (直译为,类型错误:“类型”对象不可下标) 2.示例代码 1list=[1,2,3,4,5]2deffn(x):3returnx**245res =map[fn,list]6res = [iforiinresifi > 10]7print(res) 3.报错原因 ...
解决方法很简单，此处加上对应的return：def processEachMapId(mapId):...commonInfoDict["MapID"] = str(mapId);return commonInfoDict;def outputInfoDictList(allInfoDictList):for index,eachInfoDict in enumerate(allInfoDictList):...print "type(eachInfoDict['MapID'])=",type(eachInfo...
编译后会报错TypeError: 'map' object is not subscriptable,在百度了后才知道,上面代码在python2当中才是正确的,在py3中,它返回的是迭代器,不是我们直接想要的list。 所以正确的做法如下: list1=['11','22'] list1=list(map(int,list1)) ...
map操作对象不能用下标描述,'map' object is not subscriptable 但是map操作对象可以用for 循环迭代找到数值 时间测试:(比较list for 循环,map操作,numpy操作,torch tensor 操作,torch tensor cuda 操作) f = lambda x : x*x*x list_r = [i for i in range(1000000)] print("device_count",torch.cuda....

9.问:map对象不支持下标吗?为什么使用下标访问其中的元素时提示“TypeError: 'map' object is not subscriptable”呢? 答:是的,map对象、enumerate对象、zip对象、filter对象、reversed对象和生成器对象这些具有惰性求值特点的对象都不支持使用整数下标访问其中的元素。可以把这类对象转换为列表、元组来一次性获取其中的...
