如何从字典中挑选键和值并构建新的字典

Question

我有一个这样的词典：{'a = 1'，'b = 2'，'c = 3'，'d = 4'，' e = 5'} 现在如何随机挑选一些键和值来构建一个新的dic？ 我希望新的DIC是会是这样的：{C = 3“， 'B = 2'}

Answer 1

这应该让你开始：

import random 

x = 2 # Amount of Random choices 
dict = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5} 
dict2 = {} 

for _ in range(x): 
    key = random.choice(list(dict.keys())) # Chose a random key 
    dict2[key] = dict[key] # Add it to new dict 
    dict.pop(key, None) # Remove from old dict, so it doesn't get picked again 

print(dict2)
