python如何确定是否为可迭代对象

from collections import Iterable

print(isinstance('abc',Iterable)) # str是否可迭代  True

print(isinstance(5,Iterable)) # 整数是否可迭代  False

print(isinstance('5',Iterable)) # str是否可迭代（区分上面的整数）  True

list_one = ['a','b','c']

for i in enumerate(list_one):

    print(i)   # 打印(0,'a') (1,'b') (2,'c')

    print(type(i)) # 类型是tuple

    print(i[0])  # 打印list的下标0 1 2

dict_one = {'name': 'zxf', 'age': 24, 'address': 'ZheJiang'}

# 迭代key

for key in dict_one:

print(key)
