Python 字典和列表習題

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

將所有大於66的值保存至字典的第一個key中，將等於小於66的值保存至第二個key中

即：{'k1':大於66,'k2':小於等於66}

 

實現的方式一：

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



實現的方式二：

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(): #判斷是否存在K1
 dic['k1'].append(i) #創建K1
 else:
 dic['k1'] = [i,] #在K1里面寫入列表i
 else:
 if "k2" in dic.keys(): #判斷是有存在K2
 dic['k2'].append(i) #創建K2
 else:
 dic['k2'] = [i,] #在K2里面寫入列表i的數值
print(dic)
