如何根据python文件中的数字创建一副卡片？

Question

这是文件：

Admiral,30,1
General,25,1
Colonel,20,2
Major,15,2
Captain,10,2
Lieutenant,7,2
Sergeant,5,4
Corporal,3,6
Private,1,10

我需要显示牌组（以列表形式）并输出有多少张牌。文件中的最后一个数字表示有多少张卡片。所以甲板上有 1 张海军上将卡，2 张上校，10 张列兵，等等。

以下是我目前的代码：

numFile = open("ranks.dat", "r")

#list fields
rankList = []
skillList = []
numberList = []

while True:
    text = numFile.readline()
    text = text.rstrip("\n")
    if text=="":
        break
    info = text.split(",")
    rankList.append(info[0])
    skillList.append(int(info[1]))
    numberList.append(int(info[2]))


numFile.close

print("Rank\t\tSkill\t\tNumber")
print(45*"=")
for i in range(len(rankList)):
    print("%-10s\t%3i\t\t%3i" %(rankList[i], skillList[i], numberList[i]))

如何添加卡片组列表？

如何在列表中添加卡片组？列表应该是这样的：

========================================
        Level 3 Build Deck
========================================
['Admiral', 'General', 'Colonel', 'Colonel', 'Major', 'Major', 'Captain', 'Captain', 'Lieutenant', 'Lieutenant', 'Sergeant', 'Sergeant', 'Sergeant', 'Sergeant', 'Corporal', 'Corporal', 'Corporal', 'Corporal', 'Corporal', 'Corporal', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private']

Answer 1

重构发布的软件

以下简化发布的代码并创建相同的输出

注意：重命名文件ranks.txt（即txt文件通常以txt结尾 后缀）。

with open("ranks.txt", "r") as f:
  rankList, skillList, numberList = zip(*[x.rstrip().split(',') for x in f])

skillList = [int(x) for x in skillList]
numberList = [int(x) for x in numberList]

print("Rank\t\tSkill\t\tNumber")
print(45*"=")
for i in range(len(rankList)):
    print("%-10s\t%3i\t\t%3i" %(rankList[i], skillList[i], numberList[i]))

建立套牌列表

Inspired by

建造甲板

deck = [rank for rank, number in zip(rankList, numberList) for i in range(number)]
print(deck)

或者等效地使用 for 循环

deck = []
for i in range(len(rankList)):
  rank = rankList[i]
  number = numberList[i]
  for repeat in range(number):
    deck.append(rank)

输出

['Admiral', 'General', 'Colonel', 'Colonel', 'Major', 'Major', 'Captain', 'Captain', 'Lieutenant', 'Lieutenan
t', 'Sergeant', 'Sergeant', 'Sergeant', 'Sergeant', 'Corporal', 'Corporal', 'Corporal', 'Corporal', 'Corporal
', 'Corporal', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Private', 'Priva
te', 'Private']

说明

构建套牌列表理解

deck = [rank for rank, number in zip(rankList, numberList) for repeat in range(number)]

创建排名对的序列和该排名的数量

zip(rankList, numberList)

遍历这些对

 for rank, number zip(rankList, numberList)

根据每对中的number 重复排名

 [rank for rank, number in zip(rankList, numberList) for repeat in range(number)]

完整的软件

numFile = open("ranks.dat", "r")

#list fields
rankList = []
skillList = []
numberList = []

while True:
    text = numFile.readline()
    text = text.rstrip("\n")
    if text=="":
        break
    info = text.split(",")
    rankList.append(info[0])
    skillList.append(int(info[1]))
    numberList.append(int(info[2]))

numFile.close

print("Rank\t\tSkill\t\tNumber")
print(45*"=")
for i in range(len(rankList)):
    print("%-10s\t%3i\t\t%3i" %(rankList[i], skillList[i], numberList[i]))

deck = []
for i in range(len(rankList)):
  rank = rankList[i]
  number = numberList[i]
  for repeat in range(number):
    deck.append(rank)

print(deck)
