Correct Capital


You are given a word in which letters can be in different cases. Your task is to check whether the case was used correctly in the line. If everything is correct - return True, if there are errors - return False.

Examples of the correct use of cases:

  • All characters in the string are in uppercase. For example, "CHECKIO";
  • None of the characters are in uppercase. For example, "checkio";
  • Only the first character is in uppercase. For example, "Checkio".
  • Input: String (str).

    Output: Logic value (bool).

    assert correct_capital("CheCkio") == False
    assert correct_capital("CHECKIO") == True
