答案 0 :(得分：3)
1）打开文件：
txt = open(filename)
在python中有3种类型的打开文件。阅读，写作和追加。您可以使用＆＃39; r＆＃39;，＆＃39; w＆＃39;指定它们。和＆＃39; a＆＃39;作为开放函数的第二个参数：
txt = open(filename, 'r')
但是如果你想读写一个文件，比如在这个纸牌游戏中，你必须使用＆＃39; r +＆＃39; （或＆＃39; w +＆＃39;和＆＃39; a +＆＃39;）。然后你也可以读写而不是只读这个文件。
2）语法无效：
filename.write(name "=" score)
你应该写：
filename.write("%s=%d" % (name, score))
3）＆＃39;得分＆＃39;变量：
在游戏功能中出现错误：
if score > 1: # checks if score is better than 1, then writes score to txt doc
UnboundLocalError: local variable 'score' referenced before assignment
您必须将得分变量设置为全局变量（在游戏功能中）。因此范围不仅用于游戏功能本身：
global score
4）＆＃34;游戏逻辑中的小错误＆＃34;：
在你的if-else语句中，你这样做：
if dealer > user:
...
elif user < dealer:
...
else
elif条件与if条件相同。您必须将其更改为：
if dealer > user:
...
elif user > dealer:
...
else
5）读写文件：
你写了例如：
filename.write("\n")
但文件名只是一个字符串。你必须使用open（）函数返回的＆t; txt＆＃39; -variable。
txt.write("\n")
完成所有这些更改后，代码如下所示：
from sys import argv # imports the opening of two separate files
import random # imports the 'random' string
script, filename = argv # sets two variables, one on the py file and the other on the txt file
txt = open(filename, 'r+') # opens the txt file
# card variables assigning values
Two = 1
Three = 2
Four = 3
Five = 4
Six = 5
Seven = 6
Eight = 7
Nine = 8
Ten = 9
Jack = 10
Queen = 11
King = 12
Ace = 13
# chooses a random card
score = 0 # score at game start
def scores(): # this will print out the current high scores.
print "The current scores in file: %r" % filename
print txt.read() # prints the open txt file
def start(): # this is sent after the scores. welcomes play to game.
print "Welcome %s, the computer and you will both draw a card. Whoever gets the higher card wins" % name
print "Try to in a row to go on the high scores!"
print "Good luck %s" % name
game() #starts the game
def game(): # begins the actual game
global score
print "The dealer draws a card..."
dealer = random.choice([Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King, Ace]) # gives the dealer a random card
print "You draw a card..."
user = random.choice([Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King, Ace]) # gives the user a random card
if dealer > user: # if dealer wins
print "You lose!"
if score > 1: # checks if score is better than 1, then writes score to txt doc
txt.write("\n")
txt.write("%s=%d" % (name, score))
txt.close()
else: # aren't good enough, game quits
print "You didn't get a score over 1, you suck and aren't going to be on high scores."
txt.close()
elif user > dealer: # if user wins
print "Nice! You won that round"
score = score + 1 # adds 1 to current score
game() # next round
else:
print "Um no idea what you did there, again?"
game()
scores() # score def
name = raw_input("First off let's get your name. \n >") # asks the users name for recording high scores
start() # start def
我希望我能帮到你！
答案 1 :(得分：0)
如果要写入文件，则应以写入模式打开它：
txt = open(filename, mode='w')
