The code should now handle input validation, ensuring that the range provided is valid and the start number is smaller than the end number.
Construct a function to output the product of two numbers. Additionally, handle the case where one or both of the input numbers are negative. However, you should not use the multiplication operator (*) or any built-in multiplication functions. Implement the function using only bitwise operations, bitwise shifting, and basic arithmetic operations.
Get a user input and check if the input is a palindrome. The input should not exceed 100 characters and should only contain alphabetic characters. Additionally, the program should ignore any leading or trailing spaces in the input. You should also account for both uppercase and lowercase characters when determining if the input is a palindrome.
Create a function that takes a specific input and produces a specific output using only addition and subtraction operators. The function must also satisfy the following constraints: the input must be a positive integer between 1 and 1000, and the output must be a negative integer between -1000 and -1. Additionally, the function must be implemented using recursion and without using any built-in math functions.
Using the inspect module, create a program that counts the number of lines of code in a specific function within a module. The program should prompt the user to enter the name of the module and the name of the function they want to analyze. The program should then display the total number of lines of code within that function, excluding any comments or blank lines. Additionally, implement a feature to analyze multiple functions within a module and display the total number of lines of code for each function. Furthermore, allow the user to enter regular expressions to define specific patterns to exclude from the line count, such as excluding lines with a specific keyword or specific variable names. Finally, implement a feature to analyze not only Python modules but also modules in other programming languages such as Java or C++.
Create a function that generates a series of Fibonacci numbers up to a certain number of items. The function should also calculate the sum of all the prime Fibonacci numbers in the series. Additionally, the function should check if the sum is a palindrome and return the smallest prime palindrome number within the generated series of Fibonacci numbers.
Write a function called "print_characters" that takes a string as input and prints each character of the string using a for loop. The function should also count and print the number of vowels in the string. The string may contain uppercase and lowercase letters, numbers, special characters, and whitespace. The function should ignore whitespace characters and consider vowels to be "a", "e", "i", "o", and "u" (both uppercase and lowercase). The function should also handle strings with a length of up to 1000 characters.
