在python中提取文件中的所有字符串

Question

这些是文件的内容：-

org.mule.api.processor.LoggerMessageProcessor: Process Started MessageID=1AMULE
One
Two
Three
org.mule.api.processor.LoggerMessageProcessor: Process Completd MessageID=1AMULE
org.mule.api.processor.LoggerMessageProcessor: Process Started MessageID=2BMULE
org.mule.api.processor.LoggerMessageProcessor: Process Completd MessageID=2BMULE

我在这里要提取字符串1A,1B，即在python中的org.mule.api.processor.LoggerMessageProcessor: Process Started MessageID=之后和MULE之前。

Answer 1

您可以在str.split上使用"="

例如：

with open(filename) as infile:
    for line in infile:
        if "=" in line:
            print(line.split("=")[1].strip())

输出：

1AMULE
1AMULE
2BMULE
2BMULE
