What will happen if special characters are used in identifiers?

Using special characters like !, @, or # in identifiers is against Python’s syntax rules and results in a syntax error.

Example of Using Special Characters in Identifiers

total$sum = 100 # SyntaxError due to the "$" symbol

To avoid this error:

  • Use only letters, digits, and underscores.
  • Start identifiers with a letter or an underscore.
