arcpy.AddCodedValueToDomain_management('presidentos.gdb', "amerikanske presidenter", 'code', 'df.to_dict[code]')

should be

arcpy.AddCodedValueToDomain_management('presidentos.gdb', "amerikanske presidenter", code, df.to_dict[code])

By the way, this looks like a lot of typing in interactive mode. Why not save it as py file and run the script? So you will be able to reuse it whenever you need

I tried this and got the following error:

Error:
Runtime error 
Traceback (most recent call last):
  File "<string>", line 2, in <module>
TypeError: 'instancemethod' object has no attribute '__getitem__'

Sorry, I miss the parenthesis after to_dict, i.e. the last argument should be
df.to_dict()[code]

By the way i just started using python to simplify some of my work. And i have no education on it what so ever, so I really appreciate any kind of help!

take a look at
https://python-forum.io/Thread-How-to-Ex...ython-code

You can write your code in any texteditor (e.g. Notepad, but not Word). However better look at some real IDE, that will have added benefits like code highlighting, code completion, debugger, linter, etc. I would recommned VS Code.
