Python没有运行代码

问题描述：

我写了一个刚刚停止工作的python脚本。我不知道为什么如此任何帮助将不胜感激。控制台不显示任何东西。我在底部调用函数开始，但没有运气。在空闲Python没有运行代码

import random 

year = 1 
our_score = 0 
their_score = 0 
games_played = 0 

#opponent's strategy: 
def op_strategy(): 
    for i in range (0,1):

    if rand == 0: 
     return "war" 
    if rand == 1: 
     return "peace" 


def start(): 
    global our_score, their_score, year 
    print "=====" 
    print "Year " + str(year) 
    print "Our Score: " + str(our_score) 
    print "Their Score: " + str(their_score) 
    print "" 
    strategy = raw_input("What is your strategy this year? ") 
    inputs(strategy) 

def inputs(strategy):

Python恨你。你做了什么来关闭虚拟机？ – duffymo 2012-07-17 23:13:58

你知道如何使用python调试器吗？你可以自己回答这个问题和类似的问题。 – 2012-07-17 23:14:11

运行代码时会发生什么？ – Blender 2012-07-17 23:14:25

答

代码正在执行，但它在raw_input调用中被卡住，并且在打印完成之前不打印，当然由于没有打印任何内容，用户不知道这样做。
缓冲区不会自动刷新。如果您使用-u选项启动python，则会使用raw_input调用刷新缓冲区，并且提示将很明显。

装入这件事，你会看到以下错误：

SyntaxError: name 'our_score' is assigned to before global declaration (, line 1)

其中一个线：

def inputs(strategy): 
our_score = 0 
global our_score, their_score, year

至于详细here:

If the global statement occurs within a block, all uses of the name 
specified in the statement refer to the binding of that name in the top-level 
namespace... i.e. the namespace of the module containing the code block

你已经分配了一个局部变量our_name然后你告诉函数使用一个同名的全局变量。解决这个问题后应该没有问题。
