①

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key in d: print(str(key) ':' str(d[key])) list:[1, 2, 3] 1:123 111:python3 tuple:(4, 5, 6)

②

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key in d.keys(): print(key) 1 list 111 tuple

2. 遍历字典的值value

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for value in d.values(): print (value) [1, 2, 3] 123 python3 (4, 5, 6)

3. 遍历字典的项

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for item in d.items(): print(item) ('list', [1, 2, 3]) (1, 123) ('111', 'python3') ('tuple', (4, 5, 6))

4. 遍历字典的key-value

①

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key,value in d.items(): print(key,value) list [1, 2, 3] 1 123 111 python3 tuple (4, 5, 6)

②

>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for (key,value) in d.items(): print(key,value) list [1, 2, 3] 1 123 111 python3 tuple (4, 5, 6)
