The Python function shift_ characters takes a string as input and returns a new string where each alphabetic character is shifted to the next character in the alphabet.
How does the function work ?
The function iterates over each character in the input string. If the character is alphabetic (char. isalpha()), it checks for the special cases of 'z' and 'Z'. If it encounters 'z', it appends 'a' to the result, and for 'Z', it appends 'A'
For other alphabetic characters, it finds the next character by converting the character to its ASCII value (ord (char)), adding 1 to it, and then converting it back to a character (chr (ord(char) + 1)).
Non-alphabetic characters are appended to the result string as is.
