How to return "raw lines" to their previous state?

Question

Python

I get the data from the sqlite database, they are in the form:
"Hello \nworld"
If you write print(abc), it will display Hello \nworld!
How do I get the \n characters to be escaped again?

Answer 1

It looks like the database has 'Hello \\nworld!' stored.
In this case, the quick fix is:

#Python 2.X
print '"Hello,\\nworld!"'.decode('string_escape')
#Python 3.X
print(b"Hello,\\nworld!".decode('unicode_escape'))

But it's better to work with the database using an ORM that will do everything for you or google "python unescape string"
