使用 python 中的日志文件中的日期和計(jì)數(shù)匹配單詞進(jìn)行分組

使用 python 中的日志文件中的日期和計(jì)數(shù)匹配單詞進(jìn)行分組

慕桂英4014372 2023-10-26 16:31:04
我有 myFileMonitor.log 文件，其中包含以下數(shù)據(jù)。我想根據(jù)日期分組和匹配單詞（如 - 'Created', 'modified', 'moved', 'deleted'）將數(shù)據(jù)保存在 csv 文件中，如下所示。因此，在日志文件中，我想根據(jù)日期過濾數(shù)據(jù)，并計(jì)算這些單詞在日志中出現(xiàn)的次數(shù)。請(qǐng)協(xié)助。myFileMonitor.log:2020-09-25 16:31:58 - Security Alert!

使用 defaultdict 的做法非常正確，但是有一種簡單的方法可以檢查某個(gè)鍵是否在一行中，這就是關(guān)鍵字in。如果您事先知道關(guān)鍵字是什么，那么這就是我將使用的代碼：


from collections import defaultdict

def collect_data():

    try:

        occurrences = defaultdict(lambda: defaultdict(int))

        keys = {'Created', 'modified', 'deleted', 'moved'}

        with open('myFileMonitor.log', 'r') as f:

            for line in f:

                date = line.split(' ')[0]

                for key in keys:

                    if key in line:

                        occurrences[date][key] += 1


        for date in occurrences:

            for key in occurrences[date]:

                print(date+','+key+','+str(occurrences[date][key]))


    except FileNotFoundError:

        print("Exception error: File not found!")

輸出：


2020-09-25,Created,4

2020-09-25,moved,3

2020-09-25,modified,10

2020-09-25,deleted,2

2020-09-30,Created,4

2020-09-30,modified,3

2020-09-30,deleted,3

您還可以執(zhí)行一些操作，例如定義要打印日期和鍵的順序或在循環(huán)之前進(jìn)行排序（如果需要）。
