其中,sep=''和end='\n'均是print()的关键参数,sep的默认值为空,end默认值为换行符,这就是print()在输出后默认换行的原因。相应的,解决办法就是对end赋值:print(something, something,.., end=''),使end值为空,这个换行就消除了。 原文地址:http://wpp9977777.blog.163.com/blog/static/4625100720119290562...

"print(do_something_unreliable()) 运行这个程序,大家可以看到每次打印“just have a test”这句话的次数都不一样。这是由于我们程序中只要随机整数大于1就会打印并且抛出异常。但是由于我们有装饰器函数 retry,所以在发生异常就会重新再次执行方法,直到随机整数大于1,就会打印“good job!”。
