下面是日志文件中的一些示例文本。我需要提取每次出现的“上传的事件”和发生的下一个“}”之间的所有文本。我还添加了一个我需要返回的样本(请注意,这只是一个样本——我将把该方法应用于更一般的情况)。另外,我的输出格式不是很好,只是一个想法。接近那个很好,我可以从那里进行格式化,内容最重要:

我试过使用:
start = ‘Event uploaded, ’
end = ‘}’
new = entry[entry.find(start)+len(start):entry.rfind(end)]
和其他几种方法(包括正则表达式),但没有运气......任何帮助将不胜感激,谢谢!
编辑(尝试):
with open(target_logs) as log:
do_print = False
event_key = 'Event uploaded,'
for line in log:
line = line.strip()
if do_print:
sys.stdout.write(line[line.rfind(']') + 1:].strip())
if event_key in line:
do_print = True
sys.stdout.write(line[line.find(event_key) + len(event_key):].strip())
elif line.endswith('}'):
do_print = False
print()
