I want to extract two keywords of interest from a log file and calculate the time difference between them. Each line in the log starts with a timestamp in the following format. For example, I want to calculate the duration between the keywords abc and def. 01-20 09:18:42.637 721 4768 I abc : START a 01-20 09:18:43.968 721 777 I hhhhh : fffffff 01-20 09:19:02.886 11719 11864 D def :end cccc duration_List.append(float("%.3f" % (start_time.timestamp() - start_time.timestamp()))) ^^^^^^^^^^^^^^^^^^^^^^ OSError: [Errno 22] Invalid argumen my code is def Get_Line_Time_s(line): time_format = "%m-%d %H:%M:%S.%f" dt = datetime.strptime(line[:18], time_format) return dt def Calculate_Time(logcat_file, keyword_start, keyword_end): cmd = "grep -aEi '%s|%s' %s" % (keyword_start, keyword_end, logcat_file) print("\n Using command: %s" % cmd) tmp_file = TEMP_FILE if os.path.exists(tmp_file): os.remove(tmp_file) with open(tmp_file, "w") as tmp: subprocess.run(["bash", "-c", cmd], stdout=tmp) tmp.close() logs = open(tmp_file, "r") read_lines = logs.readlines() duration_List = [] pre_line = None for line in read_lines: if line.find(keyword_end) != -1 and pre_line != None: end_time = Get_Line_Time_s(line) print(end_time) start_time = Get_Line_Time_s(pre_line) duration_List.append(float("%.3f" % (end_time.timestamp() - start_time.timestamp()))) pre_line = line logs.close() return duration_List I am a new Python programmer, and I encountered this error but don’t know how to troubleshoot it. Could you please provide some guidance and help? Thank you very much! It fixed by change code as follows @Vũ Trí Anh Hoàng def Get_Line_Time_s(line): time_format = "%m-%d %H:%M:%S.%f" dt = datetime.strptime(line[:18], time_format) current_year = datetime.now().year dt = dt.replace(year=2025) return dt Continue reading...
