"PYTHON"

Declare a list that is initialized with six of your favorite sports teams. Print out the number of teams to the shell. Use a for loop to print out the teams to the shell.

2. a. Declare a sporting goods list, initially with no elements.
b. Use a while loop to prompt the user for a sporting goods item and append the item to the list.
c. Break out of the loop when the user enters exit; do NOT append the word exit to the list.
d. Write a for s in sport_list loop to print out the elements in the list to the shell.
(BONUS) Add code to handle a ctrl-c exit.

3. a. Create a pressure list which initially contains no elements. b. Using the SenseHat, take 25 pressure measurements and store each measurement as a floating-point number in the list. Be sure to have the program sleep for a second or two between each measurement.
c. After recording the measurements, calculate the average of the pressure measurements- use the sum function and display the average on the SenseHat.

4. Allow the user to enter new sporting goods items at a specific index in the sporting goods list. Prompt the user for the index and the new item’s name.

5. Sort the sporting goods list in ascending order. Use a while loop to print out each item in the sporting goods list.

---Allow the user to delete an item from the sporting goods list. Prompt the user for the item’s name.

-- Sort the sporting goods list in descending order. Use a while loop to print out each item in the sporting goods list.


---a. Create a week_tuple and assign the days of the week as strings to the week_tuple.

b. Print out the elements in the week_tuple.

---a. The following list has been declared as follows:
credit_list = [24,3,15]

b. Convert the credit_list to a tuple named credit_tuple.

c. Print out the elements in the credit_tuple.

---a. Write an initialize_list_values function that takes in a number for the number of elements in a list and an initial value for each element. The function creates a new list and appends the elements with the initial value to the new list.

b. Pass in 5 and 3.4 as arguments to the intital_list_values and store the returned list in data_list.

c. Use a loop to print the elements of the data_list.

---a. Create a tuple named inventory_items_tuple which has Raspberry Pi 3, Raspberry Pi 2, and Raspberry Pi Camera Module.

b. Create a tuple named out_of_stock_items_tuple which has Raspberry Pi Zero. (Hint: add a , after “Raspberry Pi Zero”.)

c. Append these two tuples together into the all_items_tuple. Print out each element in the tuple using a for loop and use the len function to determine the number of elements in the tuple.
  

--a. Create a list of lists consisting of three rows and four columns, which were initially set to 0.
b. Prompt the user to initialize each element in the list of lists.
c. Compute the sum of all of the elements in the list. You may use the sum function.
d. Prompt the user to enter a row number and use a loop to calculate the sum of the elements in the row and print out the sum.

Answer 1

Solution:

Given data:

1)

teams = ["Denver Broncos","Atlanta Braves","Baltimore Ravens","Los Angeles Lakers","Dallas Cowboys","Atlanta Falcons"];
print('The list of sports team is:');
for i in range(0,6): #since we know that there are 6 teams, we can have a range from 0 to 6, where the indices will go from 0 to 6-1
    print(teams[i]); # print each team name

CODE:

OUTPUT:

2)

sport_list = []; #Declare a sporting goods list, initially with no elements
item = input('Enter a sporting good: '); #Read the first sporting item
while item.lower()!="exit": # until exit is entered, we need to continue with the loop
    #also item name is converted to lowercase so that exit written in any case can be handled
    sport_list.append(item); #append the item to list
    item = input('Enter a sporting good: '); #list the next item
print('The sporting goods list is: ');
for s in sport_list: #using for loop
    print(s); #print each item in the sport_list   

CODE:

OUTPUT:

3)

from sense_hat import SenseHat
from time import sleep

pressure = []; #Create a pressure list which initially contains no elements.
i = 0; # no of pressure values read is initialized to 0
sense = SenseHat(); #create a senseHat variable

while i < 25: # the loop goes on for 25 iterations
    p = sense.get_pressure(); #get the pressure
    pressure.append(sense); #append pressure to the list
    sleep(1); # sleep for 1 second
    i = i+1; #increment the count of pressure values read
  
sumval = sum(pressure); #sum up the pressures using the sum function
avg = sumval/25; #find the average

print('Average pressure = ', avg); #display average

CODE:

4)

sport_list = ["Bottles","Shoes","Protein"]; #Declare a sporting goods list
item = input('Enter a sporting good: '); #Read the sporting item
pos = int(input('Enter the index for new item: ')); #read the position for new item
sport_list.insert(pos,item); #insert item at given index
print(sport_list); #display the sport_list
          

CODE:

OUTPUT:

5)

sport_list = ["Bottles","Shoes","Protein","Belt","First Aid Kit","Cap"]; #Declare a sporting goods list
print('Original List: ',sport_list); #display original list
sport_list.sort()#sort the list by default in acending order
print('Sorted List (Ascending Order):');
i = 0; #iterator
while i < len(sport_list): #wehile i is less than length of list
    print(sport_list[i]); #print the list value
    i = i+1; #increment the iterator

CODE:

OUTPUT:

6)

sport_list = ["Bottles","Shoes","Protein","Belt","First Aid Kit","Cap"]; #Declare a sporting goods list
print('Original List: ',sport_list); #display original list
item = input('Enter the item to be deleted: ');
if item in sport_list: #if item is present in the list
    sport_list.remove(item); #remove the item
    print(item,'deleted successfully');
    print(sport_list); #display the updated list
else:
    print(item, 'not present in list'); #else, print item is not in the list

CODE:

OUTPUT:

7)

sport_list = ["Bottles","Shoes","Protein","Belt","First Aid Kit","Cap"]; #Declare a sporting goods list
print('Original List: ',sport_list); #display original list
sport_list.sort(reverse=True)#sort the list in descending order
print('Sorted List (Descending Order):');
i = 0; #iterator
while i < len(sport_list): #wehile i is less than length of list
    print(sport_list[i]); #print the list value
    i = i+1; #increment the iterator

CODE:
