字典迭代
obj = {"name": "tenro", "age": 27, "sex": "男"}
#遍历字典的键
for key in obj:
print(key)
#遍历字典的🈯值
for value in obj.values():
print(value)
#同时遍历字典中的键和值
for key, value in obj.items():
print(key)
print(value)
print(key, ":", value)
列表及元祖迭代
arr = ['tenro', 28, '男']
#迭代出数组里面的元素
for value in arr:
print(value)
# 迭代出数组里面的索引及对应的元素
for i, value in enumerate(arr):
print(i, ":", value)
tup = [(1, 1), (2, 2), (3, 3)] #数组里面放入元祖
tuq = [[1, 1], [2, 2], [3,3]] #二维数组
for(x, y) in tup:
print(x, y)
for(z, w) in tuq:
print(z, w)
for x, y in tup:
print(x, y)
for x, y in tuq:
print(z, w)
字符串迭代
str = "my name is tenro, i'm 28 years old and a cute boy"
for i in str:
print(i)
