1、有如下值集合 [11,22,33,44,55,66,77,88,99,90...]，将所有大于 66 的值保存至字典的第一个key中，将小于 66 的值保存至第二个key的值中
l=s.split() print(l) dic={} for item in l: if item in dic: dic[item]+=1 #字典的赋值 else: dic[item]=1 print(dic)
2、有字典{‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}，获取字典的关键字
dic={‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}
for i in dic:
print(i)
>>>hello
alex
say
sb
3、有字典{‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}，获取字典的值
dic={‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}
for i in dic.values():
print(i)
>>>
2
2
1
2
4、有字典{‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}，获取字典的键值对
dic={‘hello‘: 2, ‘alex‘: 2, ‘say‘: 1, ‘sb‘: 2}
for i,v in dic.items():
print(i,v)
>>>
hello 2
alex 2
say 1
sb 2
