中间有的行前面没有Thread Name:1.1的标识

如果你需要获取从"Thread Name:1.1 Started"到"Thread Name:1.2 Completed"之间的所有行，包括没有标识的行，你可以使用以下代码：

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

这将输出：

Thread Name:1.1 Started
Thread Name:1.0 Running
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

注意，这种方法假定"Thread Name:1.1 Started"和"Thread Name:1.2 Completed"是唯一的标识符。如果有其他行包含相同的文本，代码可能会输出不正确的行。
