![### Educational Python Programming Exercises
1. **Add the element 8 to the end of the list**:
```python
numbers = [1, 2, 3, 4, 5, 6, 7]
```
Complete the list to:
```python
numbers = [1, 2, 3, 4, 5, 6, 7, 8]
```
2. **Create a tuple of even numbers from 0 to 50**:
```python
even = (0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50)
```
3. **Sort the list in descending order**:
Given list:
```python
lst = [50, 90, 70, 80, 60]
```
Sorted list:
```python
lst = [90, 80, 70, 60, 50]
```
4. **Return the string with all lowercase letters and without any whitespaces at the beginning or end**:
```python
username = 'Stu@TTU.edu.jo '
```
Processed username:
```python
username = 'stu@ttu.edu.jo'
```
5. **Print the first three elements in the tuple**:
Given tuple:
```python
numbers = (1, 2, 3, 4, 5, 6, 7)
```
First three elements:
```python
print(numbers[:3]) # Output: (1, 2, 3)
```
6. **The function returns the value of \( x^p \)**:
Define function:
```python
def my_func(x, p):
return x ** p
```
For example:
```python
print(my_func(2, 3)) # Output: 8
```
7. **Print the average of the list**:
Given list:
```python
lst = [1,](https://content.bartleby.com/qna-images/question/0e647ec0-44e1-4533-83ba-7e8e6bdd8750/22a74a51-0afa-4ad6-9c6c-b80b4f64c337/iciowoo_processed.jpeg)

- Boolean Satisfaction Problem Boolean Satisfiability Problem (SAT) (https://en.wikipedia.org/wiki/Boolean_satisfiability_problem) is one of the most important problems in Computer Science. SAT is a problem that has NP-Complete complexity, where the only way to solve the problem is to try all the possibilities and check which one is correct. [LO 1, LO 2, LO 3 & LO 4,] Briefly describe how you used Backtracking to solve the Boolean Satisfiability Problem. Note that your solution must have exponential complexity.

(https://projecteuler.net/problem=27) The quadratic formula n^2 + n + 41 will produce 40 primes for consecutive integer values 0 <= n <= 39. However, when n = 40, this formula will not generate a prime number. Another interesting quadratic formula n^2 – 79n + 1601 produces 80 prime numbers for consecutive values 0 <= n <= 79. The Question: find a and b such that when -999 <= a <= 999 and -1000 <= b <= 1000, the quadratic form ?^2 + ? × ? + ? produces the maximum number of primes for consecutive values of n, starting with n = 0.
