python中的可迭代对象有列表、字符串、元组、字典几种

1.列表

L = list(range(100))for i in L:
print(i)

2.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)

3.元组

T = tuple(range(100))for i in T:
print(i)

4.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)
