我需要使用Python预处理推文.现在我想知道什么是正则表达式分别删除所有的标签,@ user和推文的链接？

例如,

1. original tweet: @peter I really love that shirt at #Macy. http://bet.ly//WjdiW4
   • 处理过的推文: I really love that shirt at Macy

2. 原始推文: @shawn Titanic tragedy could have been prevented Economic Times: Telegraph.co.ukTitanic tragedy could have been preve... http://bet.ly/tuN2wx
   • 处理过的推文: Titanic tragedy could have been prevented Economic Times Telegraph co ukTitanic tragedy could have been preve
3. 原始推文: I am at Starbucks http://4sh.com/samqUI (7419 3rd ave, at 75th, Brooklyn)
   • 处理过的推文: I am at Starbucks 7419 3rd ave at 75th Brooklyn

我只需要每条推文中有意义的单词.我不需要用户名,或任何链接或任何标点符号.
