需要帮助使用一个列表中的值来查找其他列表的值

Question

这是我的代码：

def collectData():
print ("Please use correct spelling\n")
print("Choose what game type this is")

getGameType = input(" FFA: 1\n 1v1: 2\n 2v2: 3\n 3v3: 4\n 4v4: 5\n")
if getGameType == "1":

 FFAPlayerList = []

 getFFAMaxLen = (int)(input("How Many players were in this FFA?: "))

 print("Please enter playername as well as placing, seperated by a comma\n(playerName,placing) One player per entry. \n")

 while len(FFAPlayerList) < getFFAMaxLen:
     getFFAPlayers = input("format: playerName,Placing::: ").split(',')
     FFAPlayerList.append(getFFAPlayers)

 with open("C:\\Users\\Twinklenugget\\Documents\\NQGroup\\Databases\\NQMasterDatabase.csv", 'r') as ffaDatabaseExtract:
     reader = csv.reader(ffaDatabaseExtract)
     ffaDatabaseList = list(reader)

     FFAPlayerList.append(ffaDatabaseList)

 print (FFAPlayerList)






collectData()

原谅格式化，它实际上都是正确的。我相对来说是python和编码的新手。我的目标是能够获取存储在FFAPlayerList中的值（播放器名称）并使用这些字符串在ffaDatabaseList中查找相同的字符串。在从ffaDatabaseList找到相同的字符串之后，我需要从ffaDatabaseList的第二列中获取值并将它们附加到FFAPlayerList中。我到底该怎么做呢？即使是正确方向的指针也会很棒。
