Process escape sequences in a string in Python

Let's say I have a raw string like r'\n' that corresponds to '\\n'. Is there a way to interpret the raw string as the "normal" string '\n' with the line break meaning?
You can get a newline by r'\n'.replace("\\n", "\n")

I am looking to type from the Python Console in Pycharm to respond to a call from input(). I would like to somehow get a newline into this string, but when I try to literally type "\n", input() automatically escapes the escape backslash into something like result = "\n" so that what I typed exactly will be printed out if I use print(result).

I have a question regarding my code below:
Input: A DNA string Pattern (ex: 'AAAACCCGGT')
Output: The complementary string (ex: 'TTTTGGGCCA')
def Complement(Pattern):
comPattern=Pattern.translate(str.maketrans({'A':'T','T':'A','G':'C','C':'G'}))
return comPattern
I tried using str.replace() method multiple times for above problem, but it did not work. Any idea why?

how can you format a string of this form in Python 3?
'''{name}{{name}}'''.format(name="bob")
the desired output is: bob{bob}, but the above gives: bob{name}.
one solution is to add another argument to format:
'''{name1}{name2}'''.format(name1="bob", name2="{bob}")
but this is excessive. is there a way to properly escape { such that inner {x} can still be interpolated and one can only pass a single name to format?
Add one more level of {}:
'''{name}{{{name}}}'''.format(name="bob")
which outputs:
bob{bob}

I wanted to replace a string : 'li\\oa' by 'ext'
but I get this error
error: octal escape value \505 outside of range 0-0o377
I know that the problem is: string containing these chracters '\\', so the question is : How can i read these backslashes as a string.
df['col']= df['col'].replace(['li\\oa'],['ext'], regex=True)
You have to escape the two backslashes by adding one "\" for each one :
df['col']= df['col'].replace(['li\\\\oa'],['ext'], regex=True)
You can declare a string as raw (with an r in front of it) and it will print all its characters:
>>> string = r'li\\oa'
>>> print string
'li\\oa'

I'm trying to write code to a python file from a python program
Example:
f.write("output.write(str(fib(int(line))) + '\n')")
I want the newline symbol to actually be written to the file and not place an actual newline in the file. How would I go about doing this?
You just need to escape the backslash with another backslash:
... + '\\n'
Or use raw strings:
... + r'\n'
try adding another backslash \ before the newline symbol like so:
f.write("output.write(str(fib(int(line))) + '\\n')")
