Write a Python program that prompts the user to enter a sequence of lowercase words and stores in a list only those words whose first letter occurs again elsewhere in the word (e.g., "baboon"). Continue entering words until the user enters an empty string ("", not " "), at which point your program should print the list. You may want to create a helper function (a function that accomplishes some smaller part of your main task) that takes in a single string, and returns True if the first letter is repeated, or False otherwise. You could use a loop to do this, but you may also want to consider just using slicing and the in keyword, or the .count method.

In python
Create a helper function as well
![**Python Programming Exercise: Word Repetition Detection**
**Objective**: Develop a Python program that allows a user to input a series of lowercase words. The program should store words in a list where their first letter appears more than once within the word (e.g., "baboon"). Input continues until the user inputs an empty string (""), followed by outputting the final list.
**Guidance**:
- Consider creating a helper function that takes a single word as input, returning `True` if the first letter repeats within the word, or `False` if it does not.
- While a loop can achieve this, you might also explore using slicing and the `in` keyword, or the `.count` method.
- Use an appropriate `while` loop condition. Note that using `while(True)` might be functional but is generally considered poor style.
**Example Execution**:
```
Enter a word: im
Enter a word: a
Enter a word: member
Enter a word: of
Enter a word: the
Enter a word: imperial
Enter a word: senate
Enter a word: on
Enter a word: a
Enter a word: diplomatic
Enter a word: mission
Enter a word: to
Enter a word: alderaan
Enter a word:
['member', 'imperial', 'alderaan']
```
