 🎉 CONGRATULATIONS ! 🎉
+## 💻 Exercises: Day 5
+
+### Exercises: Level 1
+
+1. Declare an empty list
+empty_list = ()
+2. Declare a list with more than 5 items
+list = [A, B, C, D, E, F, G]
+3. Find the length of your list
+print('number of items on the list:', len(list))
+4. Get the first item, the middle item and the last item of the list
+print(list[0])
+print(list[1])
+print(list[-1])
+5. Declare a list called mixed_data_types, put your(name, age, height, marital status, address)
+mixed_data_types = ['Sara', 250, 310.5, False, 'Iran') # LOL
+6. Declare a list variable named it_companies and assign initial values Facebook, Google, Microsoft, Apple, IBM, Oracle and Amazon.
+it_companies = ['Facebook', 'Google', 'Microsoft', 'Apple', 'IBM', 'Oracle', 'Amazon']
+7. Print the list using _print()_
+print(it_companies)
+8. Print the number of companies in the list
+print(len(it_companies))
+9. Print the first, middle and last company
+print(it_companies[0])
+print(it_companies[2])
+print(it_companies[-1])
+10. Print the list after modifying one of the companies
+it_companies[2] = 'X'
+print(it_companies)
+11. Add an IT company to it_companies
+it_companies.append('nvidia')
+12. Insert an IT company in the middle of the companies list
+it_companies.insert(2, 'hp')
+13. Change one of the it_companies names to uppercase (IBM excluded!)
+it_companies[0] = it_companies[0].upper()
+14. Join the it_companies with a string '#;  '
+new_list = it_companies.append("#;  ")
+15. Check if a certain company exists in the it_companies list.
+is_true = 'IBM' in it_companies
+print(is_true)
+16. Sort the list using sort() method
+it_companies.sort()
+17. Reverse the list in descending order using reverse() method
+it_companies.reverse()
+18. Slice out the first 3 companies from the list
+it_companies[0:3]
+19. Slice out the last 3 companies from the list
+it_companies[-3:]
+20. Slice out the middle IT company or companies from the list
+it_companies[1:-1]
+21. Remove the first IT company from the list
+it_companies.pop(0)
+22. Remove the middle IT company or companies from the list
+it_companies.del(1:-1)
+23. Remove the last IT company from the list
+it_comapnies.pop()
+24. Remove all IT companies from the list
+it_companies.clear()
+25. Destroy the IT companies list
+del it_companies
+26. Join the following lists:
+
+    ```py
+    front_end = ['HTML', 'CSS', 'JS', 'React', 'Redux']
+    back_end = ['Node','Express', 'MongoDB']
+    ```
+joined = front_end + back_end
+
+27. After joining the lists in question 26. Copy the joined list and assign it to a variable full_stack. Then insert Python and SQL after Redux.
+full_stack = joined.copy()
+exra = ['Python, 'SQL']
+full_stack.extend(extra)
+
+### Exercises: Level 2
+
+1. The following is a list of 10 students ages:
+
+```sh
+ages = [19, 22, 19, 24, 20, 25, 26, 24, 25, 24]
+```
+# Sort the list and find the min and max age'
+ages.sort()
+print(ages)
+print(min(ages), max(ages))
+# Add the min age and the max age again to the list
+new = [min(ages), max(ages)]
+ages = ages + new
+print(ages)
+# Find the median age (one middle item or two middle items divided by two)
+# Find the average age (sum of all items divided by their number )
+ave = sum(ages) / len(ages)
+print(ave)
+# Find the range of the ages (max minus min)
+ra = max(ages) - min(ages)
+print(ra)
+# Compare the value of (min - average) and (max - average), use _abs()_ method
+d = abs(min(ages) - ave) 
+e = (max(ages) - ave)
+comp = d > e
+print(comp)
+print(median(ages))
+
+1. Find the middle country(ies) in the [countries list](https://github.com/Asabeneh/30-Days-Of-Python/tree/master/data/countries.py)
+countries[1:-1]
+1. Divide the countries list into two equal lists if it is even if not one more country for the first half.
+
+def split_list(list):
+    half = len(list)//2
+    return list[:half], list[half:]
+
+split_list(countries)
+
+1. ['China', 'Russia', 'USA', 'Finland', 'Sweden', 'Norway', 'Denmark']. Unpack the first three countries and the rest as scandic countries.
+1st, 2nd, 3rd, *scandic = ['China', 'Russia', 'USA', 'Finland', 'Sweden', 'Norway', 'Denmark']
