Either Python or Sololearn can't handle the £ symbol. If you add this line: print([k for k in otherInvalid]) you'll see that £ is replaced by ú. You can add these lines to enable unicode support: import unicodedata import sys, codecs sys.stdout = codecs.getwriter('utf_16')(sys.stdout.buffer, 'strict') Unfortunately, now £ will be replaced by a different symbol in Sololearn when the input prompt is used and the code still won't work :-/

I think your code might run in other platforms. It's just that Sololearn seems to use a different encoding, so when you enter the pound sign, it is recognized as "ú". You can't really change that. It's not a problem with your code but with the way that Sololearn handels user input (I think).

Also there is a nice method to check wheater a string is a valid identifier: str.isidentifier() Your validator function could be as easy as this from keyword import iskeyword def Validator(v): if v.isidentifier() and not iskeyword(v): return True return False

You can find methods for built-in types in the original documentation. https://docs.python.org/3/library/stdtypes.html#string-methods
