$1.$ In this lab you will write a Python script that will generate random passwords from the given list

variable many$\_$words$\_$list. Your script should start by assigning a variable user$\_$number to a value

to be entered by the user. This number should be validated and must be between $3$ and $7,$ inclusive.

This value would refer to the number of words to be chosen randomly from the list variable

many$\_$words$\_$list. Depending on the value of user$\_$number, your code should randomly choose

that number of words from the many$\_$words$\_$list. Lastly, your script should concatenate these words

into one string to create the password and print it on the screen.

Hint: You will need $$random$$ to be imported. You are free to explore its methods.

$2.$ Next, define the following two functions in your code:

rep$\_$with$\_$upper $-$ This function takes a string as its only parameter and returns a new string value.

The function should create the new string value by replacing a character randomly chosen inside the

given parameter with its uppercase version $($e$.$g$.$ a $-->$ A$).$ In your modified script, you will call this

function by passing the password created in Question#$1$ as the argument value.

swap$\_$letters $-$ This function takes a string as its only parameter and returns a new string value.

The function should create the new string value by swapping the first two characters of the given

parameter with the ones in the last two $($e$.$g$.$ Password $-->$ rdsswoPa$).$ In your modified script, you

will call this function by passing the password returned from rep$\_$with$\_$upper function as the

argument value.

Now, modify your script for Question#$1$ in the following manner: Using your answer to Question#$1,$

create the initial password; then using this password as the argument value to the rep$\_$with$\_$upper

function create a new password; finally using this new password as the argument value to the

swap$\_$letters function create the final version of the password. Your modified script should print

both the initial and the final versions of the password created.

SAMPLE OUTPUT $($bold parts are entered by user$)$:

Please enter a value $($from $3$ to $7)$ for the number of words: $13$

Invalid value!

Please enter a value $($from $3$ to $7)$ for the number of words: $1$

Invalid value!

Please enter a value $($from $3$ to $7)$ for the number of words: $4$

Initial password: pythonsurelemonunix

Final version of the password: ixthonsuRelemonunpy

$3.$ In this last question, add your code the following: Open a file named $$store$.$txt$$ in write mode.

Write your last password from the previous question. The file should have only one line, which is the

password you have generated.
