Pythonで選択したキーからランダムな値を出力します

Question

選択したキーからランダムな値を出力したいとします。コードの中には、コードを説明するコメントがあります。

cases = { 
'wildfire' : { 
    'blue' : ['1', '2', '3', '4', '5'], 
    'purple' : ['6', '7', '8', '9', '10'], 
    'pink' : ['11', '12', '13', '14', '15'], 
    'red' : ['16', '17', '18', '19', '20'], 
    'knives' : ['k', 'b', 'f'] 
    }, 
'phoenix' : { 
    'blue' : ['1', '2', '3', '4', '5'], 
    'purple' : ['6', '7', '8', '9', '10'], 
    'pink' : ['11', '12', '13', '14', '15'], 
    'red' : ['16', '17', '18', '19', '20'], 
    'knives' : ['k', 'b', 'f'] 
    }, 
'gamma' : { 
    'blue' : ['1', '2', '3', '4', '5'], 
    'purple' : ['6', '7', '8', '9', '10'], 
    'pink' : ['11', '12', '13', '14', '15'], 
    'red' : ['16', '17', '18', '19', '20'], 
    'knives' : ['k', 'b', 'f'] 
    }, 
'chroma' : { 
    'blue' : ['1', '2', '3', '4', '5'], 
    'purple' : ['6', '7', '8', '9', '10'], 
    'pink' : ['11', '12', '13', '14', '15'], 
    'red' : ['16', '17', '18', '19', '20'], 
    'knives' : ['k', 'b', 'f'] 
    }, 
} 
#First keys in dictionary are cases which can be selected by user 
#The keys in cases dictionary are scaled from common to uncommon (top to    bottom) 
#Values in the cases dictionary are the skins. 
case_keys = 10 
#case_keys are used to open cases 
while case_keys >0: 
resp=raw_input("Which case would you like to open? ") 
for i in cases: 
    if resp == i: 
     chance = random.randint(1, 100) 
     """HELP HERE. The skins are classed by rarity. E.g blue is common 
but purple is more rare than blue and so forth. E.g blue is assigned to 25, 
purple to 17, pink to 10, red to 5, knives to 1. E.g 45(chance) >= x, output:blue is chosen, and from its list a random skin is selected."""

はここに手足に出て行くかもしれませんが、多分これはこのスニペットを実行しているから

import random 

cases = { 
    'wildfire' : ['1', '2', '3', '4', '5'], 
    'phoenix' : ['6', '7', '8', '9', '10'], 
    'gamma' : ['11', '12', '13', '14', '15'], 
    'chroma' : ['16', '17', '18', '19', '20'], 
    } 


user_input = random.choice(cases.keys()) 
# user_input = one of 'wildfire', 'phoenix', 'gamma', or 'chroma' 
index = random.randint(0, len(cases[user_input])) 
# index = random integer between 0 and 4 used to index cases 

chance = random.randint(1, 100) 

for i, n in enumerate([35, 17, 5, 2]): 
    if chance >= n: 
     print "You've won a %s skin." % cases[user_input][index] + \ 
       " With a chance of, %s" % chance 
     break 

サンプル出力するのに役立ちます：

You've won a 15 skin. With a chance of, 84 
You've won a 8 skin. With a chance of, 88 
You've won a 20 skin. With a chance of, 76
