[英]python parse log file: find two specific strings in different lines and concatenate in one and write to another file! Avoiding blank lines
我的日志喜歡這個文件
我需要看起來像什么:
行:5,錯誤:帳戶維度的成員不是基本級別。|>>>>>>A1399
行:6,錯誤:沒有這樣的成員|>>>>>>401700
我需要解析一個日志文件,只找到感興趣的錯誤並將它們寫入另一個文件。 下面是使用兩個標簽( 'Line:','>>>>>>' )的代碼我需要獲取這兩個標簽之后的所有字符串並連接到一個新行中。
我得到很多空行,兩個標簽在不同的行中。
先感謝您!
def main():
fo = open("C:\\Users\\yannis\\py_script\\1198.log", "r", encoding="ISO-8859-1")
ofile = open("C:\\Users\\yannis\\py_script\\out.txt",'a', newline='')
member = ""
erro = ""
f1 = fo.readlines()
for x in f1:
erro = (x[x.find('Line:'):])
member = (x[x.find('>>>>>>'):])
linha = (erro + member)
print(linha)
ofile.write(linha)
continue
fo.close()
ofile.close()
main()
def log_parser(path):
with open(path, 'r', encoding='utf-8') as f:
temp = dict()
for index, line in enumerate(f.readlines()):
_line_except = line[:-1]
[day, time, level, something, *arg] = _line_except.split(' ')
if 'Error:' in arg and 'Line:' in arg:
temp = {
"log_info": " ".join([day, time, level, something]),
"log_str": " ".join(arg)
}
elif len(arg) == 1:
print("{log_info} {log_str} || {other_args}".format(
log_info=temp['log_info'],
log_str=temp['log_str'],
other_args=arg[0])
)
else:
continue
if __name__ == '__main__':
log_parser("log.txt")
你會得到..

當您不在日志文件中寫入“>>>>12345”時,將會發生錯誤。 -> 它將在臨時字符串之前被丟棄。 你應該認出它。
