Question

我目前正在尝试为自己制作的游戏记录高分。想法是记录分数，并针对文件检查匹配的用户名。如果它们匹配并且记录的分数在文件上较低，则创建一个新文件，将复制分数较低的一行以外的所有内容，然后记录当前的用户名和分数。然后删除旧文件，然后将新文件重命名以匹配。

不幸的是，这似乎不起作用。该代码似乎无法复制，意味着我必须放入另一个脚本以确保这样做，然后有时记录不正确的结果（较低），然后从错误的位置读取它们（readfile。[row]）。我是使用另一种方法还是进一步追求这种方法更好？

import csv, os, sys
def scorewriter():
replac = 0
writein = 1
string_score = str(score)
with open('highscores.txt','r') as csvfile:
    highscoresReader=csv.reader(csvfile)
    for row in highscoresReader:
        for field in row:
            #recording high scores
            if field == username and string_score > row[1]:
                #MUST get to at least here
                     with open('highscores_temp.txt','a') as csvfiletemp:
                         highscoresWriter=csv.writer(csvfiletemp)
                         for row in highscoresReader:
                             for field in row:
                              #something wrong here, doesn't sort properly?
                                 if field == username:
                                     writein = 0
                                     replac=1

highscoresWriter.writerow([username,string_score])        
                                 else:

highscoresWriter.writerow([field,row[1]])

            elif field != username:
                continue

            elif field == username and string_score <= row[1]:
                writin = 0
                continue

if writein == 1:
    with open('highscores.txt','a') as csvfile:
        highscoresnewWriter = csv.writer(csvfile)
        highscoresnewWriter.writerow([username,string_score])
if replac == 1:
    csvfile.close()
    csvfiletemp.close()
    os.remove(pathtofile)

这似乎过于复杂。最好将所有数据读入dict，然后在掌握了分数与高分的逻辑之后。

import csv

def write_score(hs_file_name, username, score):

    high_scores = dict()
    with open(hs_file_name) as hsfile:
        for row in csv.reader(hsfile):
            try:
                high_scores[row[0]] = row[1]
            except IndexError:
                pass

    if username not in high_scores:
        high_scores[username] = score
    elif high_scores[username] < score:
        high_scores[username] = score
    else:
        return False

    with open(hs_file_name, mode="w") as hsfile:
        writer = csv.writer(hsfile)
        for k, v in high_scores.items():
            writer.writerow([k, v])

    return True

例如这样的事情。您甚至可以让它返回True或False，以便您可以判断这是高分游戏。不必制作临时文件，覆盖旧文件会更容易。

使用CSV
