岩石，紙和剪刀改進：Python 2.7？

Question

我是新來的python，並試圖寫一個有關上述主題的小項目。

import random 


option = ["rock", "paper", "scissors"]; 
pc_selection = ["rock", "paper", "scissors"]; 
pc_move = random.choice(pc_selection) 

#------------------------------------------------------------------------------- 
def first_condition(): 
    select = raw_input("Please select your choice\n") 
    print "Your choice:", select 
    if select in option: 
     pc_move 
     print "Computer choice:", pc_move 
    else: 
     first_condition() 

    if select == pc_move: 
     print "Result: draw" 
    elif select == "rock" and pc_move == "paper": 
     print "Result: Computer wins" 
    elif select == "paper" and pc_move == "scissors": 
     print "Result: Computer wins" 
    elif select == "scissors" and pc_move == "rock": 
     print "Result: Computer wins" 

    elif select == "rock" and pc_move == "scissors": 
     print "Result: You win" 
    elif select == "paper" and pc_move == "rock": 
     print "Result: You win" 
    elif select == "scissors" and pc_move == "paper": 
     print "Result: You win" 


first_condition() 

我知道我的代碼是不是很有效（最快和最聰明的），所以我的問題是：

哪一部分，我可以修改，使我的項目儘可能短不失其functionaility，即使用其他函數可以減少我的代碼的長度？

謝謝！

Answer 1

選項列表中的每個選項都被其前面的選項打敗。如果選擇不同，則可以假定用戶贏得，如果計算機沒有選擇列表中用戶選擇的項目。例如：

import random 

option = ["scissors", "paper", "rock"] # I reversed the original list 
#---------------------------------------------------------------------- 
def first_condition(): 
    pc_move = random.choice(option) # there only needs to be 1 option list 
    select = raw_input("Please select your choice\n") 
    print "Your choice:", select 
    if select in option: 
     print "Computer choice:", pc_move 
    else: 
     return first_condition() 
    if pc_move == select: 
     print("Draw") 
     return 
    # find the index of the user's choice 
    index = option.index(select) 
    # did the pc choose the item before this one?  
    you_win = option[index-1] != pc_move 

    print("You %s" % ("win" if you_win else "lose")) 

while True: 
    print("-"*50) 
    first_condition()
