如何解决分析日志文件时如何获得所有行的输出？
python loganalyzer.py [filepath_to_logfile] [action]
指定的操作决定了脚本输出的内容。 当输入 error 或 notice 作为操作时，输出为：
date : message
date : message
date : message
date : message
但是脚本并没有输出所有的行...为什么？

它只有 34 行中的 17 行。
这是我所有的代码：
import argparse
error = {}
notice = {}
log_file = 'test.log'
# Functions
def load():
with open('test.log') as logfile:
for line in logfile:
parts = line.split('[error]')
if len(parts) == 2:
error[parts[0]] = parts[1]
parts = line.split('[notice]')
if len(parts) == 2:
notice[parts[0]] = parts[1]
def errors():
for date,info in error.items():
print(date + ' : ' + info)
def notices():
for date,info in notice.items():
print(date + ' : ' + info)
def statistics():
file = open('test.log','r')
error_counter = 0-1
content = file.read()
errors = content.split('[error]')
for error in errors:
if error:
error_counter += 1
print('Errors: ' + str(error_counter))
notice_counter = 0-1
notices = content.split('[notice]')
for notice in notices:
if notice:
notice_counter += 1
print('Notices: ' + str(notice_counter))
# Run
if __name__ == '__main__':
load()
notices()
# parser = argparse.ArgumentParser()
# parser.add_argument('logfile',help = 'Run program by typing python.exe logglooker.py [path_to_logfile] [action]')
# parser.add_argument('notice',help = 'Use this action to output all the date and message of all notice entries.')
# parser.add_argument('error',help = 'Use this action to output all the data and message of all error entries.')
# parser.add_argument('statistics',help = 'Use this action to output how many errors and notices it is in the logfile.')
# args = parser.parse_args()
# log_file = args.logfile
我还没有弄清楚如何让 argparse 正常工作，这就是为什么代码看起来有点奇怪。
要分析的 test.log 就是这个。
