python可迭代_python中可迭代对象有哪些
Python中的可迭代对象有哪些？Python中的可迭代对象有：列表、元组、字典、字符串；常结合for循环使用；
判断一个对象是不是可迭代对象:from collections import Iterable
isinstance(list(range(100)), Iterable)
isinstance(Say YOLO Again.)
列表:

print(i)
元组:T = tuple(range(100))for i in T:
print(i)
字典:dic = {name: chen, age: 25, loc: Tianjin}
# 以列表的形式返回
keylist(dic.keys())
# 以列表的形式返回
valuelist(dic.values())
# 循环key
for key in dic:
print(key)
# 循环value
for value in dic.values():
print(value)
# 循环key, value
for key, value in dic.items():
print(key, value)
字符串:S = Say YOLO Again!for s in S:
print(s)
返回索引-元素对:
for i, value in enumerate(Say YOLO Again.):
print(i, value)
