python 如何快速转义路径字符串中的斜杠

Question

有没有自带的库将'/opt/www/html'转义成'/opt/www/html'

目前使用

    path_list = path.split("/")
    path_str = ""
    for i in path_list:
        if len(i) <= 0:
            continue
        path_str += "\/" + i

Answer 1

old_str = '/opt/www/html'
new_str = old_str.replace('/', '\/')
print(new_str)
