22.8 LAB 5 D FALL 19 : Using math functions

This lab problem demonstrates the use of import module. The Python programming language has many strengths, but one of its best is the availability to use many existing modules for various tasks, and you do not need to be an experienced computer programmer to start using these modules.

We have given you some incomplete code; note that the very first line of that code contains an import statement as follows:

import math

This statement enables your program to use a math module. A module is a collection of instructions saved together as a whole. So, in this lab you are using the math module. Any time we choose to use a module, we must use an import statement to bring this module into the program. When we import the math module, all the computer instructions contained in the math module are made available to our program, including any functions that have been defined.

If you are interested in finding out what is in the math module you can always go to the Python docs and take a look: Python Docs

Example of using the math module:
print(math.floor(5.4))
will use the floor() function as defined in the math module, and in this case with the argument 5.4, will result in printing the value 5.

Below is the definition of your problem that we are asking you to solve using the math module.

Prompt the user for floating point numbers x, y and z. For the x value your you will the use the following prompt Enter x value:inside of your input statement. Using the same approach you will prompt the user for y and z.

- Given three floating-point numbers x, y, and z, 
your job is to output
     - the **square root** of x,
     - the **absolute value** of (y minus z) , and 
     - the **factorial** of (the **ceiling** of z).  

Example of a sample run:

Enter x value:5

Enter y value:6.5

Enter z value:3.2

Then the expected output from these entries is:

2.23606797749979 3.3 24

Hint: For finding out the square root you will need to use math.sqrt(), you need to use the website recommended above to find out which functions to use in order to solve the rest of the lab problem.

16) Define a 3 to 8 active low decoder. Which number is the input and which is the output? Is 8 related to 3? Explain.

17) Define a 8 to 1 multiplexer. Which number is the input and which is the output? Is 8 and 3 are the only numbers or there are other set(s) of numbers? Explain.

20) Design a combinational circuit that has two ASCII inputs and generates “1”only if the two ASCII are equivalent.

Problem 3

Write a function called makesentence() that has three parameters: nouns, verbs, and gerunds. Each parameter is a list of strings, where nouns list has noun strings (such as 'homework'), verbs list has veb strings (such as 'enjoy'), and gerunds list has gerund strings (those -ing words, such as 'studying'). The function will go through all these lists in a systematic fashion to create a list of all possible sentences that use all the noun, verb, and gerund strings. The function then returns the list of sentences.

Each sentence has the following format: 'I' followed by a verb, followed by a noun, followed by 'when ', followed by a gerund, exactly in this order.. For example: 'I enjoy homework when studying' uses the noun 'homework', verb 'enjoy', and gerund 'studying'.

Consider that we have the following lists:

some_nouns = ['homework', 'music', 'breaks']

some_verbs = ['enjoy', 'ignore']

some_gerunds = ['studying', 'sleeping', 'hiking']

After we write the function definition, we call the function, save its return value in the variable result, and print out the result:

result = makesentence(some_nouns, some_verbs, some_gerund)

print(result)

The output of obtained from the call above is:

['I enjoy homework when studying', 'I enjoy homework when sleeping', 'I enjoy homework when hiking', 'I enjoy music when studying', 'I enjoy music when sleeping', 'I enjoy music when hiking', 'I enjoy breaks when studying', 'I enjoy breaks when sleeping', 'I enjoy breaks when hiking', 'I ignore homework when studying', 'I ignore homework when sleeping', 'I ignore homework when hiking', 'I ignore music when studying', 'I ignore music when sleeping', 'I ignore music when hiking', 'I ignore breaks when studying', 'I ignore breaks when sleeping', 'I ignore breaks when hiking']

Part A Think about how to solve this problem and the computational steps of your solution BEFORE you write the Python code. Explain (1) what computations you’ll instruct Python and (2) why. Write your explanations in the order in which the computations should occur.

Part B

#1 Using the explanations of the computational steps of your solution, in an Active Code scratchpad, write the implementation. The implementation has the following structure: your function definition, followed by the three list assignments, followed by the function call and print() call, as follows:

[ your function definition goes in here ]

some_nouns = ['homework', 'music', 'breaks']

some_verbs = ['enjoy', 'ignore']

some_gerunds = ['studying', 'sleeping', 'hiking']

result = makesentence(some_nouns, some_verbs, some_gerund)

print(result)

Copy and paste the code of your function definition

Copy and paste the output you get when you run & save your code

This maze project assumes that a cell is rectangular, and that there is an entrance into and an exit from the cell.  What if the entrance and the exit were closed doors and the user was to choose which door leads to the next cell?  What would be some pseudocode for this scenario?

Notice that " switch case " statements are used for this project along with " if " statements.  Can they be interchanged and still produce the same results [ i.e., make the switch case statements into if statements, and the if statements into switch case statements ] ? Support your answer!

Information Security

-Why are modes of operation needed for block ciphers like AES?

If the action is Balance 'B’, use a print balance function to return and print an account balance. You will need to write a function called printbalance.

a. Create a prompt for the user to input the account action. There are three possible actions:

Create a function to print the account_balance, print the account actions and create the action for outputting the account balance outputting.

Input Information

The following data will be used as input in the test:

userchoice = input ("What would you like to do?")
userchoice = 'B'

Output Information

Your current balance:
500.25

1. The opening balance has been assigned to a variable called account_balance equal to $500.25. Notice the use of the 'float' method in order to ensure that 'account_balance' is a float value.
2. Request the action to be taken on the account.
3. Write a print balance function that returns the account balance.
4. Create the action for selection ‘B’, Account Balance, to call the print balance function then print the account balance once the value is returned from the function.
5. Test your code.

import sys# importing the sys library

# account balance
account_balance = float(500.25)

#PPrint the balance
# This is a custom function, it returns the current balance upto 2 decimal places
def printbalance():
print("Your current balance : %2f" % account_balance)
#the function for deposit
#This is a custom function
def deposit():
deposit_amount = float(input("Enter amount to deposit : ")) # takes in input for deposit amount
balance = account_balance + deposit_amount #calculates balance
print("Deposit was $%2f, current balance is $%2f" %(deposit_am ount,balance)) # prints out the balance
#function for withdraw
#this is a custom function
def withdraw():
withdraw_amount = float(input("Enter amount to withdraw")) # takes in the withdraw amount
if(withdraw_amount > account_balance): #checks whether the amount is more than balance or not
print("$%2f is greater than account balance $%2f\n" %(withdraw_amount,account_balance)) #if yes then
print wd amount greater than balance
else:
balance = account_balance - withdraw_amount
print("$%2f was withdrawn, current balance is $%2f" % (withdraw_amount, balance))
# User Input goes here, use if/else conditional statement to call function based on user input

userchoice = input("What would you like to do?\n")

if (userchoice == 'D'):
# here deposit function is called
deposit()
elif userchoice == 'W':
# here withdraw function is called
withdraw()
elif userchoice == 'B':
# here printbalance function is called
printbalance()
else:
# it ends the program execution
sys.exit()
