使用Python将日志文件转换为CSV文件 [英] Converting a log file into a csv file using Python

问题描述

我在工作中遇到以下问题-我需要获取一个日志文件，其中的各项安排如下:

I have the following problem at work - I need to take a log file with items arranged as follows:

A1
B1
C1
A2
B2
C2
.
.
.
An
Bn
Cn

我需要一个完整的csv文件，如下所示:

I need a complete csv file like so:

A1,B1,C1
A2,B2,C2
A3,B3,C3
...
An,Bn,Cn

如何使用python脚本执行此操作?

实际上，格式是通过以下方式写出的-

Actually, the format is written out in the following way -

Voltage: A1
Current: B1
Power: C1

如何将其转换为-

Voltage, Current, Power
A1,B1,C1

推荐答案

import csv

with open('myfile.log') as file:
    lines = file.read().splitlines()
    lines = [lines[x:x+3] for x in range(0, len(lines), 3)]

    with open('yourcsv.csv', 'w+') as csvfile:
        w = csv.writer(csvfile)
        w.writerows(lines)

请注意，点仍然存在，它们将被视为值(因此它们也将由逗号分隔)

Note that the dots are still there and they would be treated as values (so they'll be separated by comma's too)
