#CODE_CHALLENGE_2 #FUNCTION #LIST_SLIC #STRING
1. Commercial bank of Ethiopia realized that their policy of using the first five letters of an employee’s last name as a user name isn’t ideal when they have multiple employees with the same last name.
Write a function called account_generator that takes two inputs, first_name and last_name and concatenates the first three letters of each and then returns the new account name.
2. They also wants to update how they generate temporary passwords for new employees.
Write a function called password_generator that takes two inputs, first_name and last_name and then concatenate the last three letters of each and returns them as a string.
Example: first_name = "Asibeh"
last_name = "Tenager"
expected output: user_name = AsiTen
temp_password = behger

Scrabble
In this project, you will process some data from a group of friends playing scrabble. You will use dictionaries to organize players, words, and points.
There are many ways you can extend this project on your own if you finish and want to get more practice!
N.B: You should go through each task to complete this project.

Tasks
letters = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]
points = [1, 3, 3, 2, 1, 4, 2, 4, 1, 8, 5, 1, 3, 4, 1, 3, 10, 1, 1, 1, 1, 4, 4, 8, 4, 10]
1. I have provided you with two lists, letters and points. You would like to combine these two into a dictionary that would map a letter to its point value.
Using a list comprehension and zip, create a dictionary called letter_to_points that has the elements of letters as the keys and the elements of points as the values.
2. Our letters list did not take into account blank tiles. Add an element to the letter_to_points dictionary that has a key of " " and a point value of 0.
3. We want to create a function that will take in a word and return how many points that word is worth.
Define a function called score_word that takes in a parameter word.
4. Inside score_word, create a variable called point_total and set it to 0.
5. After defining point_total, create a for loop that goes through the letters in word and adds the point value of each letter to point_total.
You should get the point value from the letter_to_points dictionary. If the letter you are checking for is not in letter_to_points, add 0 to the point_total.
6. After the for loop is finished, return point_total.
7. Let’s test this function! Create a variable called asibeh_points and set it equal to the value returned by the score_word() function with an input of "ASIBEH".
8. We expect the word ASIBEH to earn 11 points:
(A + S + I + B + E + H)
Let’s print out asibeh_points to make sure we got it right.
9. Create a dictionary called player_to_words that maps players to a list of the words they have played. This table represents the data to transcribe into your dictionary:
player1 wordNerd Lexi Con Prof Reader
BLUE EARTH ERASER ZAP
TENNIS EYES BELLY COMA
EXIT MACHINE HUSKY PERIOD
10. Create an empty dictionary called player_to_points.
11. Iterate through the items in player_to_words. Call each player player and each list of words words.
Within your loop, create a variable called player_points and set it to 0.
12. Within the loop, create another loop that goes through each word in words and adds the value of score_word() with word as an input.
13. After the inner loop ends, set the current player value to be a key of player_to_points, with a value of player_points.
14. player_to_points should now contain the mapping of players to how many points they’ve scored. Print this out to see the current standings for this game!
If you’ve calculated correctly, wordNerd should be winning by 1 point.

Hi, this is a simple example to practice Numpy. Go through each line of code and ask if you have any questions.
#CODE_CHALLENGE_3 #LIST #SWAP_TWO_NUMBERS
#Q: The next iteration of Asibeh Tenager will feature an extra-infuriating new item, the Purple Shell. When used, it warps the last place racer into first place and the first place racer into last place. Write a python function purple_shell and implement the Purple Shell's effect.
Note: Given a list of racers, set the first place racer (at the front of the list) to last
place and vice versa.
N.B: use swap mechanism
given list: racers = ["Asibeh", "Naol", "Obang"]
output list = ["Obang", "Naol", "Asibeh"]

Fuzzy matching Algorithm:
The process of automatically finding text strings that are very similar to the target string. In general, a string is considered "closer" to another one the fewer characters you'd need to change if you were transforming one string into another. So "apple" and "snapple" are two changes away from each other (add "s" and "n") while "in" and "on" and one change away (rplace "i" with "o"). You won't always be able to rely on fuzzy matching 100%, but it will usually end up saving you at least a little time.Epython Lab via @QuizBot
