Question

I wrote a python script which just stopped working suddenly. I’m not sure why so any help would be appreciated. The console just doesn’t display anything. I called the function start on the bottom but no luck.

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):
        rand = random.randint(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):
    our_score = 0
    global our_score, their_score, year
    if str(strategy) == "peace" or str(strategy) == "war":
        print "You chose: " + str(strategy)
        op_strat = str(op_strategy())
        print "They chose: " + op_strat
    if str(strategy) == "war" and str(op_strat) == "war":
        print ">>> Everyoner to arms!"
        our_score = our_score + 1
        their_score = their_score + 1
        year = year + 1
    elif str(strategy) == "peace" and str(op_strat) == "peace":
        print ">>> Peace for everyone!"
        our_score = our_score + 3
        their_score = their_score + 3
        year = year + 1
    elif str(strategy) == "peace" and str(op_strat) == "war":
        print ">>> They crushed us!"
        our_score = our_score
        their_score = their_score + 5
        year = year + 1
    elif str(strategy) == "war" and str(op_strat) == "peace":
        print ">>> We crushed them!"
        our_score = our_score + 5
        their_score = their_score
        year = year + 1
    if str(year) == "11":
        print "====="
        print "Final"
        print str(our_score)
        print str(their_score)
        if our_score > their_score:
            print ">>>>> We win! <<<<<"
        if their_score > our_score:
            print ">>>>> They win! <<<<<"
        if their_score == our_score:
            print ">>>>> It's a tie! <<<<<"
        play = raw_input("Play again?")
        if play == "y":
            start()
        if play == "n":
            pass
        else:
            play = raw_input('Invalid response. Please enter "y" or "n".')
    if str(strategy) != "peace" and str(strategy) != "war":
        strategy = raw_input('Invalid strategy. Enter "peace" or "war": ')
        inputs(strategy)
    start()
start()

Answer 1

The code is executing, but it is stuck at the raw_input call, and not printing until it completes, which of course the user does not know to do because nothing has printed.
The buffer is not automatically flushed. If you start python with the -u option, the buffer will be flushed with the raw_input call, and the prompt will be apparent.
