存儲列表字典的問題

Question

我遇到了解析輸入文件（示例如下所示）並將信息存儲在列表/字典組合中的代碼問題。

我有了類似這樣的行（他們是棒球統計）一個CSV文件：

Reyes,Jose,Mets,SS,681,191,36,12,12,57,.280 

我能夠分裂每個字段並妥善保存它的變量，但現在的問題進入當我必須將數據存儲在數據結構中時播放。

我必須存儲每個球員的統計數據，然後將球員存儲在他們所屬的每個球隊的字典/列表中。

我的思想過程是與此類似：

DICT OF TEAMS (TEAM IS KEY, VALUE IS A DICT OF PLAYERS) 
| 
V 
DICT OF PLAYERS (THEIR FULL NAME IS KEY, VALUE IS A LIST OF STATS) 
| 
V 
LIST OF STATS (EVERY SINGLE STAT IS IN HERE) 

不幸的是，我的統計名單將填補從整個文本文件（主要是投入列表的文本文件）的信息。我試過在while循環結束時清除表，但它將清單完全清除，即使我將它存儲在播放器字典中。

也許有人可以簡化我的想法或告訴我我做錯了什麼。

我的繼承人蔘考代碼：

import sys 
from collections import OrderedDict 

if len(sys.argv) == 1: 
    filename = raw_input("No filename supplied. Please enter one now: ") 
    print "Filename supplied. Running now." 
else: 
    print "Filename supplied. Running now." 
    filename = sys.argv[-1] 

#print "\n" 

f = open(filename, "r") 
l = f.readline() 

lastName = ""  #0 
firstName = ""  #1 
teamName = ""  #2 
position = ""  #3 
atBats = ""   #4 
baseHits = ""  #5 
doubles = ""  #6 
triples = ""  #7 
homeruns = ""  #8 
rbi = ""   #9 
batingAvg = ""  #10 

fullName = "" 

teams = {} 
players = {} 
stats = [] 

while l: 
    l = l.strip("\n") 
    curCol = l.split(",") 
    l = f.readline() 

    lastName = curCol[0] 
    firstName = curCol[1] 
    teamName = curCol[2] 
    position = curCol[3] 
    atBats = curCol[4] 
    baseHits = curCol[5] 
    doubles = curCol[6] 
    triples = curCol[7] 
    homeruns = curCol[8] 
    rbi = curCol[9] 
    batingAvg = curCol[10] 

    fullName = firstName + " " + lastName 

    stats.append(lastName) 
    stats.append(firstName) 
    stats.append(teamName) 
    stats.append(position) 
    stats.append(atBats) 
    stats.append(baseHits) 
    stats.append(doubles) 
    stats.append(triples) 
    stats.append(homeruns) 
    stats.append(rbi) 
    stats.append(batingAvg) 

    players[fullName] = stats 

print players 

Answer 1

我相信你在每次迭代結束時清空您的統計列表。

while l: 
    # ... 
    stats = [] 

編輯：

啊，我明白你的問題。這是因爲，當你將列表存儲在字典中並清除它時，它也會在字典中清除它。

我相信你可以只作列表的副本在字典存儲：

import copy 
# ... 
players[fullName] = copy.deepcopy(stats) 
stats = [] 

編輯2：

另外，我相信你能做到這一點

with open(filename, 'r') as f: 
    for line in f: 
     firstName = line.split(",")[0] 
     lastName = line.split(",")[1] 
     players[firstName + " " + lastName] = line.split(",")[2:]
