注意多线程不能在python console里面断了重新拿之前变量继续跑,Python REPL(Read-Eval-Print Loop)是一种交互式编程环境。REPL本身不是为多线程交互设计的,无法直接“暂停/恢复”子线程:Python没有提供原生支持,需通过逻辑设计实现 # -*- coding: utf-8 -*-importsyssys.path.extend(['/home/charlie/ssd/t...

To terminate a loop early, you can use the___statement. To skip the current iteration of a loop and continue with the next iteration, you use the___statement.
Similar to while, for has an optional else that checks if the for completed normally. If break was not called, the else statement is run. This is useful when you want to verify that the previous for loop ran to completion, instead of being stopped early with a break. The for loop in...

Tip:If you need to terminate a script early, you can usesys.exit(). The remaining code will not be executed. import sys sys.exit(1) Imagine doing these operations for different log formats, and message types – it can get complicated and error-prone very quickly. Maybe there is another...

Inmain, we set up a loop1that runs every minute, because of theself.timeoutparameter, until the service receives the stop signal2. While it's running, we copy the script file to the target directory, execute the script, and remove the file3. ...
