How to make a newline in .txt from user input?

Question

I take a string to be saved in .txt from user. However, when I give my string like that "Line1\nLine2\nLine3"
and write this to the file, it writes the string to the first line as it is.
How can I make it so it makes a newline whenever it encounters "\n" ?

Edit: When I give my string like that to the function explicitly ( and not by an argument ),
file.write("Line1\nLine2")
It makes the newlines

Answer 1

Before writing input string to file replace "\\n" by "\n".

text = input()
text = text.replace("\\n","\n")

#write `text` to file.
