Python：通过字典迭代可以让我“int object not iterable” [英] Python: Iterating through a dictionary gives me "int object not iterable"

问题描述

这是我的功能：

def printSubnetCountList(countList):
    print type(countList)
    for k, v in countList:
        if value:
            print "Subnet %d: %d" % key, value

以下是输入函数时，传递给该字典的函数：

Here's the output when the function is called with the dictionary passed to it:

<type 'dict'>
Traceback (most recent call last):
  File "compareScans.py", line 81, in <module>
    printSubnetCountList(subnetCountOld)
  File "compareScans.py", line 70, in printSubnetCountList
    for k, v in countList:
TypeError: 'int' object is not iterable

任何想法？

推荐答案

尝试这个

for k in countList:
    v= countList[k]

或这个

for k, v in countList.items():
