在python中剥离一行之后，如何创建两个单独的列表？

Question

我在想我怎么能得到这样的文件：

Bob
120
Joe
300
Jim
175
Jack
205
Jeffrey
155
Billy
135

在那里我输出一个文件，里面只有保龄球手的名字，以及他们是否得到了完美的分数，如果他们高于平均水平还是低于平均水平。 这里是我写的代码，但它不会工作，因为我不能分裂后，换行已被删除。你知道吗

inputFile = open("bowlingscores.txt", "r")
outputFile = open("bowlingaverages.txt", "w")

lines = inputFile.readlines()
for line in lines:
    line = line.strip()
    line = line.split(" ")
    Bowler = line[0]
    Score = line[1]
    def BowlingAverages(bowlingScore):
        average = 0
        if bowlingScore > 0:
            average += bowlingScore/ len(bowlingScore)
        return average
    outputFile.write(Bowler)
    if Score == 300:
        outputFile.write("perfect")
    elif Score > BowlingAverages(Score):
        outputFile.write("above average")
    else:
        outputFile.write("below average")

outputFile.close()

Answer 1

lines = inputFile.readlines()
names = lines[0::2]
scores = lines[1::2]

如果您还想剥离/格式化行，则将最后两行替换为

names = [name.strip() for name in lines[0::2]]
scores = [int(score) for score lines[1::2]]

如果分数不是全部整数，您可能需要用float替换上面的int。你知道吗

Answer 2

如果您确信您的文件具有上述顺序

bowler_dict = dict()
for line in open(source.txt).readlines():
    try:
        score = int(line.strip())
        bowler_dict[current] = score
        current = None
    except ValueError:
        current = line.strip()

现在你有一本字典了

{'Jeffrey': 155, 'Jim': 175, 'Billy': 135, 'Joe': 300, 'Bob': 120, 'Jack': 205}

所以让我们算出平均值

>>> all_scores = bowler_dict.values()
>>> all_scores
[155, 175, 135, 300, 120, 205]
>>> average_score = sum(all_scores)/float(len(all_scores))
>>> average_score
181.66666666666666


>>> for bowler in bowler_dict:
        score =  bowler_dict[bowler]
        if score == 300:
            classify = 'PERFECT'

        if average_score < score < 300:
            classify = 'Above Average'
        else:
            classify = 'Below Average'
        print bowler, score, classify


Jeffrey 155 Below Average
Jim 175 Below Average
Billy 135 Below Average
Joe 300 Below Average
Bob 120 Below Average
Jack 205 Above Average
