Where is the problem? Variable Name Validation

Question

https://code.sololearn.com/cW3mnzHOWzN8/?ref=app
Input: £45
Output: Valid

Answer 1

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 :-/

Answer 2

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).

Thanks for your help... 😄

Answer 4

Anna So, what should be the other logic?

Answer 5

Thank you Damiano Cangini, for your help..... 😄
from where I can learn these modules in python??

Answer 6

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.
