Python 组合词典

我是python初学者。如果我想合并以下两种词典，该怎么办：

dwarf items={'coins':30,'power':11,'Knives':20,'beer':10,'pistol':2}
caves=[('A','B','C','D','E','F','G')]

我想让“侏儒”在任何一个洞穴里随机扔东西

我尝试了zip函数，但没有按预期的方式工作。 输出应如下所示：

cache={'A':0,'B':['coins':30],'C':['Knives':20},'D':0,'E':0,'F':0,'G':0}

我认为您可能正在寻找以下内容：

dwarf_items = {'coins': 30, 'power': 11, 'Knives': 20, 'beer': 10, 'pistol': 2}
caves = ['A', 'B', 'C', 'D', 'E', 'F', 'G']
drop_chance = 0.4  # change this to make it more or less likely an item will drop
cache = {}
for cave in caves:
    if dwarf_items and random.random() < drop_chance:
        item = random.choice(dwarf_items.keys())
        cache[cave] = {item: dwarf_items.pop(item)}
    else:
        cache[cave] = {}

这里有一个解决方案，我认为可能与您所寻找的非常接近：

import random

cave_names = ['A','B','C','D','E','F','G']
item_names = ['coins', 'power', 'knives', 'beer', 'pistol']

# Create the dictionary of caves, all of which have no items to start
caves = {cave : {item : 0 for item in item_names} for cave in cave_names}

# Randomly distribute the dwarf's items into the caves
dwarf_items = {'coins' : 30, 'power' : 11, 'knives' : 20, 'beer' : 10, 'pistol' : 2}
for key, value in dwarf_items.iteritems():
    for i in range(value):
        # Give away all of the items
        cave = random.choice(cave_names)
        caves[cave][key] += 1
        # Take the item away from the dwarf
        dwarf_items[key] -= 1

print(caves)

下面是一个例子，当矮人的所有物品被随机分配到洞穴中后，洞穴的尽头是什么：

{'A': {'beer': 2, 'coins': 4, 'knives': 1, 'pistol': 1, 'power': 1},
 'B': {'beer': 0, 'coins': 3, 'knives': 7, 'pistol': 0, 'power': 0},
 'C': {'beer': 1, 'coins': 2, 'knives': 1, 'pistol': 0, 'power': 3},
 'D': {'beer': 3, 'coins': 8, 'knives': 3, 'pistol': 0, 'power': 2},
 'E': {'beer': 2, 'coins': 4, 'knives': 2, 'pistol': 1, 'power': 5},
 'F': {'beer': 2, 'coins': 7, 'knives': 5, 'pistol': 0, 'power': 0},
 'G': {'beer': 0, 'coins': 2, 'knives': 1, 'pistol': 0, 'power': 0}}

洞穴不是字典。您在这里有很多语法错误。是否可以只获取一个随机副本并将项目分别放入该列表中更好？这些代码对我很有用，您使用的是什么版本？您可能需要在代码顶部添加

import random

。这是Python2.7，但在其他版本中也应该可以使用。这一个不起作用，错误消息是“dict”没有“iteritems”属性@user3285116您必须使用Python3。iteritems（）已重命名为simply items（）

>>> cache
{'A': {}, 'C': {}, 'B': {}, 'E': {'beer': 10}, 'D': {}, 'G': {}, 'F': {}}

import random

cave_names = ['A','B','C','D','E','F','G']
item_names = ['coins', 'power', 'knives', 'beer', 'pistol']

# Create the dictionary of caves, all of which have no items to start
caves = {cave : {item : 0 for item in item_names} for cave in cave_names}

# Randomly distribute the dwarf's items into the caves
dwarf_items = {'coins' : 30, 'power' : 11, 'knives' : 20, 'beer' : 10, 'pistol' : 2}
for key, value in dwarf_items.iteritems():
    for i in range(value):
        # Give away all of the items
        cave = random.choice(cave_names)
        caves[cave][key] += 1
        # Take the item away from the dwarf
        dwarf_items[key] -= 1

print(caves)

{'A': {'beer': 2, 'coins': 4, 'knives': 1, 'pistol': 1, 'power': 1},
 'B': {'beer': 0, 'coins': 3, 'knives': 7, 'pistol': 0, 'power': 0},
 'C': {'beer': 1, 'coins': 2, 'knives': 1, 'pistol': 0, 'power': 3},
 'D': {'beer': 3, 'coins': 8, 'knives': 3, 'pistol': 0, 'power': 2},
 'E': {'beer': 2, 'coins': 4, 'knives': 2, 'pistol': 1, 'power': 5},
 'F': {'beer': 2, 'coins': 7, 'knives': 5, 'pistol': 0, 'power': 0},
