問題描述
我對(duì) python 完全陌生，但我遇到了一個(gè)無法解決的嚴(yán)重問題.
I am completely new to python and I have a serious problem which I cannot solve.
我有幾個(gè)結(jié)構(gòu)相同的日志文件:
I have a few log files with identical structure:
[timestamp] [level] [source] message
例如:
[Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] error message
我需要用純 Python 編寫一個(gè)程序，它將這些日志文件合并到一個(gè)文件中，然后按時(shí)間戳對(duì)合并后的文件進(jìn)行排序.在此操作之后，我希望將此結(jié)果(合并文件的內(nèi)容)打印到 STDOUT(控制臺(tái)).
I need to write a program in pure Python which should merge these log files into one file and then sort the merged file by timestamp. After this operation I wish to print this result (the contents of the merged file) to STDOUT (console).
我不明白該怎么做，希望得到幫助.這可能嗎?
I don't understand how to do this would like help. Is this possible?
推薦答案
你可以這樣做
import fileinput
import re
from time import strptime
f_names = ['1.log', '2.log'] # names of log files
lines = list(fileinput.input(f_names))
t_fmt = '%a %b %d %H:%M:%S %Y' # format of time stamps
t_pat = re.compile(r'[(.+?)]') # pattern to extract timestamp
for l in sorted(lines, key=lambda l: strptime(t_pat.search(l).group(1), t_fmt)):
print l,
