从列表中删除略有重复的项目Python

Question

我有一个列表。它是随机的。我想要重复删除列表中的项目。

我只想要这些网址（项目）在我的列表中。

/watch?v=iOpJywrdCuQ&lc=z13ohzibgwq3yjw4u04cglzhxmioy5phrn00k 

我只会从我的列表中删除这些URL（项目）。

/watch?v=iOpJywrdCuQ&lc=z13ohzibgwq3yjw4u04cglzhxmioy5phrn00k.1479303517063659 

urlList是保存它的变量。

试验用于字符.匹配正则表达式（因为.由\.表示被保留用于any char）：

import re 
without_dot = [] 
for x in open('file.txt').read().split('\n'): 
    if not re.match('\.', x): 
     without_dot.append(x)
