The if __name__ == "__main__" block in Python allows you to define code that will only run when the file is executed directly as a script, but not when it's imported as a module into another script. Aug 12, 2024
The name of the script you are running is always in sys.argv[0]. In this script, our other arguments are our host and the port we want to connect. If those arguments are absent, we want to throw an error and exit the script. Python lets us do this in one line. The return code...
int(1),1)-datetime.timedelta(days=1)else:d2=datetime.date(int(argv[1]),int(argv[2])+1,1)-datetime.timedelta(days=1)print((d2-d1).days)if__name__=='__main__':iflen(sys.argv)!
the “assert” statement is a valuable tool for debugging. It allows you to embed checks directly into your code to ensure that specific conditions hold true at critical points. If an assertion fails—meaning the condition is False and a built-inAssertionErrorexception is raised....
if __name__ == ‘__main__’: main() After returning the banner, our script needs to check this banner against some known vulnerable programs. This also reflects a single, related function. The function checkVulns() takes the variable banner as a parameter and then uses it to make a ...
我们经常做单元测试使用的机制 if __name__ == '__main__' ,表明作为主程序运行的Python 源文件可以被视为名为 __main__ 的 module,当然以 import py 方式加载,则__name__ 不会为 __main__。在初始化 __main__ module 时会将('__builtins__', __builtin__ module)插入到其 dict 中。也就...
