python3取以Thread Name:1.1开始，一直到Thread Name:1.2中间的行

假设你有一个名为log.txt的文本文件，其中包含以下内容：

Thread Name:1.0 Started
Thread Name:1.0 Running
Thread Name:1.1 Started
Thread Name:1.1 Running
Thread Name:1.1 Completed
Thread Name:1.2 Started
Thread Name:1.2 Running
Thread Name:1.2 Completed
Thread Name:1.0 Completed

你可以使用以下代码来获取从"Thread Name:1.1 Started"到"Thread Name:1.2 Completed"之间的行：

with open("log.txt", "r") as f:
    started = False
    for line in f:
        if "Thread Name:1.1 Started" in line:
            started = True
        elif "Thread Name:1.2 Completed" in line:
            break
        elif started:
            print(line.strip())

这将输出：

Thread Name:1.1 Running
Thread Name:1.1 Completed
Thread Name:1.2 Started
Thread Name:1.2 Running
