python如何取出字符串中的转义字符

https://movie.douban.com/subject/25845392/
比如这个字符串，如何去除它的所有反斜杠

>>> s = 'https://movie.douban.com/subject/25845392/'
>>> s = s.replace('/','')
>>> print(s)
https:movie.douban.comsubject25845392
>>> 

#以下这一类才是转义字符，一样也能用replace取代
>>> t = '\'\"\a\b\n\v\t\r\f'
>>> s = '1\'2\"3\a4\b5\n6\v7\t8\r9\f'
>>> for i in t:
    s = s.replace(i,'')

    
>>> print(s)
123456789

/ 这是转义字符？

ss = 'https://movie.douban.com/subject/25845392/'
ret = ss.replace('/', '', )
