Python 字典和列表习题

有如下值集合[11,22,33,44,55,66,77,88,99,100.110,200,230,330],

将所有大于66的值保存至字典的第一个key中，将等于小于66的值保存至第二个key中

即：{'k1':大于66,'k2':小于等于66}

实现的方式一：

all_list = [11,22,33,44,55,66,77,88,99,100.110,200,230,330] 
dic = {}
list1 = [] #声明列表
list2 = []
for i in all_list: #设置循环条件
 if i>66:
 list1.append(i)
 else:
 list2.append(i)
dic['k1'] = list1
dic['k2'] = list2
print(dic)



实现的方式二：

dic = {}
all_list = [11,22,33,44,55,66,77,88,99,100.110,200,230,330]
for i in all_list:
 if i>66:
 if "k1" in dic.keys(): #判断是否存在K1
 dic['k1'].append(i) #创建K1
 else:
 dic['k1'] = [i,] #在K1里面写入列表i
 else:
 if "k2" in dic.keys(): #判断是有存在K2
 dic['k2'].append(i) #创建K2
 else:
 dic['k2'] = [i,] #在K2里面写入列表i的数值
print(dic)
