读取循环中的日志文件并打印所需结果(python)
我试图读取3个日志文件,并使用解析来提取重新查询的信息;我需要这段代码在循环中运行,如果它们满足重新查询的参数,就可以获得新行 我编写了以下代码:读取循环中的日志文件并打印所需结果(python),python,Python,我试图读取3个日志文件,并使用解析来提取重新查询的信息;我需要这段代码在循环中运行,如果它们满足重新查询的参数,就可以获得新行 我编写了以下代码: import os x_list = [] y_list = [] z_list = [] x_log = open('x.txt') for line in x_log: line = line.rstrip() if 'error' in line: x = line for x in x_lo
import os
x_list = []
y_list = []
z_list = []
x_log = open('x.txt')
for line in x_log:
line = line.rstrip()
if 'error' in line:
x = line

if not x in x_log:
x_list.append(x)
print('ERROR1',x)
y_log = open('y.txt')
for line in y_log:
line = line.rstrip()
if 'error' in line:
x = line
for x in y_list:
if not x in y_list:

print('ERROR2',x)

line = line.rstrip()
if 'error' in line:
x = line
for x in z_log:
if not x in z_list:
z_list.append(x)
print('ERROR3',x)
我正在努力实现的目标:
1.读取文件。
2.搜索相关行。
3.如果列表中不存在该信息,请附加到列表。
4.打印行
我需要帮助设置一个while循环,我在将行与列表内容进行比较时犯了一些错误
更新1:
好的,所以我通过添加以下内容使代码正常工作:
and line not in x_list:
我的原始行:
if 'error' in line:
所以现在我得到了:
if 'error' in line and line not in x_list:
完整代码:
x_list = []
y_list = []
z_list = []
x_log = open('x.txt')
for line in x_log:
line = line.rstrip()
if 'error' in line and line not in x_list:
x_list.append(line)
print('ERROR-X',line)
y_log = open('y.txt')
for line in y_log:
line = line.rstrip()
if 'error' in line and line not in y_list:
y_list.append(line)
print('ERROR-Y',line)
z_log = open('z.txt')
for line in z_log:
line = line.rstrip()
if 'error' in line and line not in z_list:
z_list.append(line)
print('ERROR-Z',line)
它做了我需要的,但我仍然需要在一个循环中运行它,有人能帮我吗
更新2:
设法使其在循环中工作,如果添加了新行并且它满足解析参数,则将打印它
代码:
优化方法:
def get_error_lines(fp, lines_set, suffix=''):
''' fp - file pointer;
lines_set - a set of unique error lines;
sufix - ERROR number(suffix) '''
for line in fp:
line = line.rstrip()
if 'error' in line and line not in lines_set:
lines_set.add(line)
print('ERROR' + suffix, line)
# using set objects to hold unique items
x_set = set()
y_set = set()
z_set = set()
with open('x.txt', 'r') as x_log, open('y.txt', 'r') as y_log, open('z.txt', 'r') as z_log:
get_error_lines(x_log, x_set, '1')
get_error_lines(y_log, y_set, '2')
get_error_lines(z_log, z_set, '3')
您编写
x\u log=open('x.txt')
,但之后,您为x\u srv\u日志中的行编写:
,您应该为x\u日志中的行更改为:
已编辑!我的原始代码中没有这个错误。我不明白你想做什么:)@MrGrj嗨,我有3个日志文件需要读取并在其中查找错误消息。然后我想将这些错误消息附加到一个列表中,并打印出来。然后重新阅读这三个文件,并将新行与列表内容进行比较,如果不在列表中,则追加并打印行;对于z_日志中的x:如果不是z_列表中的x:(…)。谢谢,但这太复杂了,我现在无法理解。
