Python program
You are given the following text file called Mytext.txt. Write a Python function called search_file that accepts the name of the file (i.e. filename) and a string to look for in the file (i.e. mystring) as parameters. The function then looks for mystring in the file. Whenever it finds the string in a line, it saves the line number and the text for that line in a dictionary. Finally, it returns the dictionary after reading all the lines in the file and populating the dictionary with all matching line numbers and line text. If an empty string or a blank string is passed as mystring then an empty dictionary is returned.
Sample Input: search_file("Mytext.txt","python")
Sample Input: search_file("Mytext.txt","")
Contents of Mytext.txt
Python is an interpreted, high-level, programming language.
Python is dynamically typed and garbage-collected.
Python was conceived in the late 1980s.
Python 2.0, was released in 2000.
Python 3.0, was released in 2008.
The interpreters are available for many operating systems.

Answer:

The function in Python is as follows:

def search_file(filename,mystring):

my_dict = {}

count = 0

file = open(filename)

lines = file.readlines()

for line in lines:

 count+=1

 if mystring.lower() in line.lower():

  my_dict[count] = line.rstrip('\n')

return my_dict

Explanation:

This defines the function

def search_file(filename,mystring):

This initializes an empty dictionary

my_dict = {}

This initializes the number of lines to 0

count = 0

This opens the file

file = open(filename)

This reads the lines of the file

lines = file.readlines()

This iterates through the lines

for line in lines:

This increments the number line

 count+=1

This checks if the string exists in the line

 if mystring.lower() in line.lower():

If yes, the line number and the string are added to the dictionary

  my_dict[count] = line.rstrip('\n')

This returns the dictionary

return my_dict

There used to be a popular type of pulp book for younger readers. They were called "Choose Your Own Adventure" novels. The idea was pretty simple. You'd start reading and then a few pages into the book, there would be a plot development that required a choice. The book might describe that you've entered a spooky house and the door has locked behind you. It would then ask you if you want to try to exit by going through the kitchen or exploring upstairs. If you chose to go into the kitchen, you'd turn to page 200, if you chose to go upstairs, you'd turn to page 43. This would repeat maybe five or six times though the book. You could re-read it a few times and try different outcomes.
In this lab you are going to create a choose your own adventure application using navigation controllers. The introduction screen to your application will contain a few lines of text to set up a story and then leave the user with a choice. Below the text, you will present two buttons that correspond to the different choices.
For example, you might see the following text on the main screen:
You are walking down the street when a tiger runs up and takes your lunch and then runs away...
Do you want to chase the tiger or run away?
Chase
Run Away
The user must then tap one of the buttons. This will move the user to a new screen with a few more lines of the story and another choice and two more buttons. You will create three (3) turning points in your story. This means that your story will have eight (8) different possible outcomes and a total of 15 screens.
Requirements
The story must ask three (3) questions, no matter how the user answers the previous question. All the questions must be different and result in a different story text.
The story must have eight (8) possible different final outcomes.
The story must include a minimum of 15 screens in total.
Create content that is appropriate and not-offensive. We will share these and play them together.
For extra credit you can add an extra screen and use inputs to capture data from the user such as a name, favorite food, or lucky number and use this data in the story.

You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???

Along with the encrypted copy, some mysterious person has also given you the following documents:

helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.

hints.txt -- Seems important.

In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:

decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")

Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

Write a MIPS assembly language program that prompts for a user to enter a series of floating point numbers and calls read_float to read in numbers and store them in an array only if the same number is not stored in the array yet. Then the program should display the array content on the console window.
Consult the green sheet and the chapter 3 for assembly instructions for floating point numbers. Here is one instruction that you might use:
c.eq.s $f2, $f4
bc1t Label1
Here if the value in the register $f2 is equals to the value in $f4, it jumps to the Label1. If it should jump when the value in the register $f2 is NOT equals to the value in $f4, then it should be:
c.eq.s $f2, $f4
bc1f Label1
To load a single precision floating point number (instead of lw for an integer), you might use:
l.s $f12, 0($t0)
To store a single precision floating point number (instead of sw for an integer), you might use:
s.s $f12, 0($t0)
To assign a constant floating point number (instead of li for an integer), you might use:
li.s $f12, 123.45
To copy a floating point number from one register to another (instead of move for an integer), you might use:
mov.s $f10, $f12
The following shows the syscall numbers needed for this assignment.
System Call System Call System Call
Number Operation Description
2 print_float $v0 = 2, $f12 = float number to be printed
4 print_string $v0 = 4, $a0 = address of beginning of ASCIIZ string
6 read_float $v0 = 6; user types a float number at keyboard; value is store in $f0
8 read_string $v0 = 8; user types string at keybd; addr of beginning of string is store in $a0; len in $a1
------------------------------------------
C program will ask a user to enter numbers and store them in an array
only if the same number is not in the array yet.
Then it prints out the result array content.
You need to write MIPS assembly code based on the following C code.
-------------------------------------------
void main( )
{
int arraysize = 10;
float array[arraysize];
int i, j, alreadyStored;
float num;
i = 0;
while (i < arraysize)
{
printf("Enter a number:\n");
//read an integer from a user input and store it in num1
scanf("%f", &num);
//check if the number is already stored in the array
alreadyStored = 0;
for (j = 0; j < i; j++)
{
if (array[j] == num)
{
alreadyStored = 1;
}
}
//Only if the same number is not in the array yet
if (alreadyStored == 0)
{
array[i] = num;
i++;
}
}
printf("The array contains the following:\n");
i = 0;
while (i < arraysize)
{
printf("%f\n", array[i]);
i++;
}
return;
}
Here are sample outputs (user input is in bold): -- note that you might get some rounding errors

This program exercise #4 wants the user to write a program in python that contains a list of movies titles, years and movie rating. You will need to display a menu option that allows the user to list all of the movies, add a movie, delete a movie and exit out of the program. This will be done using lists and the functions to add an element to a list and how to delete an element to a list. The program should be written utilizing functions in python for the main function, the display_menu function, the delete function, the add function and the list movie function. You can place this all in one python file or include them in various python files that include them into the main program. Let me know if you have any questions with this exercise. Output Screen: COMMAND MENU list - List all movies add - Add a movie del - Delete a movie exit - Exit program Command List: list 1. Monty Python and the Holy Grail, 1979, R 2.
