将列表转换为字典并向它们添加值

Question

我有一个list我想转换为dictionary并将相应的随机values添加到它们，尝试以前的答案在这里似乎没有任何工作。

这是list：

wordlist = ["apple","durian","banana","durian","apple","cherry", 
      "cherry","mango","apple","apple","cherry","durian","banana", 
      "apple","apple","apple","apple","banana","apple"] 

用简单的语法有答复将不胜感激。

Answer 1

Incase，OP正在寻找一个dictionary（想想h e是），只是做：

>>> import random 
>>> d = {} 
>>> for key in set(wordlist):      #note use of `set` 
     d[key] = random.randint(0,1000)   #the (beg,end) value is your choice 

>>> d 
=> {'apple': 816, 'mango': 342, 'banana': 231, 'durian': 765, 'cherry': 186} 

否则，如果他想在tuple与值列表，只是做：

>>> l = [] 
>>> for key in wordlist: 
     l.append((key,random.randint(0,1000))) 

>>> l 
=> [('apple', 645), ('durian', 4), ('banana', 451), ('durian', 550), ('apple', 772), 
    ('cherry', 800), ('cherry', 972), ('mango', 448), ('apple', 783), ('apple', 433), 
    ('cherry', 733), ('durian', 210), ('banana', 656), ('apple', 196), ('apple', 25), 
    ('apple', 395), ('apple', 98), ('banana', 589), ('apple', 695)]

#driver值

IN : wordlist = ["apple","durian","banana","durian","apple","cherry", 
       "cherry","mango","apple","apple","cherry","durian","banana", 
       "apple","apple","apple","apple","banana","apple"] 

Answer 2

不是太难的问题。只需要导入numpy来获得随机值。

import numpy as np 

wordlist = ["apple","durian","banana","durian","apple","cherry", "cherry","mango","apple","apple","cherry","durian","banana", "apple","apple","apple","apple","banana","apple"] 

values = [np.random.random() for x in range(len(wordlist)] 
d = {*zip(wordlist,values)} 
print (d) 

{（ '樱桃'，0.9664602705758596），（ '樱桃'，0.42093671361304286），（ '樱桃'，0.6516552865418069），（ '苹果'，0.09858653336142964），（ '香蕉'，0.3976892252830715），（”苹果'，0.9495323589015604），（'apple'，0.8118746084650151），（'apple'，0.3174994273783074），（'banana'，0.04230289240363949），（'apple'，0.35558531683946804），（'durian'，0.09960999590643527） （'apple'，0.5284715524820693），（'apple'，0.38801846246977323），（'banana'，0.5548286775310872），（'mango'，0.5978643178837114），（'durian'，0.8401078154686553），（'apple'，0.7398063632475643） ），（'apple'，0.6945371327360194）}
