You’ve learned about lists and defining your own functions. Now, you will put those skills together by writing a program that will print how many times the number 7 appears in a list.

Step 1: Practice
But before we do that, let’s visualize a bit of code to be sure you understand how it works. We are going to run the code in a visualizer. A visualizer shows you not just the output of the code but also what is happening step by step.

Go to Python Tutor Visualizer.

Then, type in this code:

my_list = [1, 2, 3, 4, 5]
for x in range(len(my_list)):
print(my_list[x])
Now, click on the Visualize Execution button. You will see a screen that has your code on the left and a blank area on the right.

Press the Next > button to begin stepping through the program. On the right, you will see a visual representation of the fact that the code has created a list; you will also see the items in the list as well as their index numbers.

Press the Next > button until you have finished the program. Did you notice how the red and green arrows showed you which lines of the program had just executed and which ones were about to execute during each step of the way through the program?

Now, let’s review the program itself. The first line of this code creates a list called my_list . Then, the second line is the command to iterate over the list using a variable that we call x . We did this iteration by making the range equal to the length of the list. For each iteration, it printed the item from the list that had the same index as the iterating variable. Now, you should be comfortable with iterating over a list and accessing each item in the list as you iterate over the list by using the incrementing variable as the index number.

Step 2: Program
Now, we’re ready to program! Leave the visualizer and go to OnlineGDB to write your program. Here is the pseudocode for your program:

Define a function called “seven_checker” that will do the following things:

Iterate over a list.
Check to see whether the number 7 is in the list.
Print how many times the number 7 appears in the list.
Create a list with 10 numbers in it. Then call the function and pass your list to the function as a parameter.

When you have tested your program, click the save button. Then click Share and copy the program link. Paste the link in a word processing document and submit using this unit’s dropbox. If your program does not work properly, also include a paragraph explaining what you did to troubleshoot it.

Answers

Answer 1

Answer:

Step 1:

def seven_checker(my_list):

count = 0

for num in my_list:

if num == 7:

count += 1

print("The number 7 appears in the list " + str(count) + " times.")

my_list = [1, 2, 3, 4, 7, 5, 7, 8, 9, 7]

seven_checker(my_list)

Step 2:

In this program, I first defined a function called "seven_checker" which takes a parameter "my_list" which is the list that we want to check for the number of times the number 7 appears in it.

In the function, I initialized a variable "count" to 0, which will keep track of the number of times 7 appears in the list.

Then, I used a for loop to iterate over the list, and for each number in the list, I checked if it is equal to 7. If it is, I incremented the count variable by 1.

Finally, I printed out the number of times 7 appears in the list using the count variable.

I then created a list with 10 numbers and called the function, passing the list as a parameter to it.

I tested the program and it gave the correct output, "The number 7 appears in the list 3 times."

I did not face any issues while writing the program and it worked as expected.

Answer 2

I understand that you want to create a Python program that counts the number of times the number 7 appears in a given list. Below is a Python code to achieve this  

def seven_checker(input_list):

   count = 0

   for num in input_list:

       if num == 7:

           count += 1

   return count

# Example list with 10 numbers

my_list = [3, 7, 2, 8, 7, 4, 7, 9, 1, 7]

# Call the function with the example list and print the result

result = seven_checker(my_list)

print("The number of sevens in the list is:", result)

How will the above program work?

You can run this code in your Python environment or OnlineGDB to see how it works. It defines a function seven_checker that takes a list as input, iterates over the elements in the list, and counts how many times the number 7 appears.

The example list my_list contains 10 numbers, and we call the function with this list to get the count of sevens in it. The result will be printed as the output.

You have an Azure AD tenant that contains a user named User1. The tenant also contains several user accounts from the Marketing department and the Human Resources department.

You need to ensure that User1 can manage the users from the Marketing department only.

What should you use?

Select only one answer.

Management groups

Administrative units

Custom Azure AD roles

Security groups that use dynamic user membership

Answers

You should use Administrative units to ensure that User1 can manage the users from the Marketing department only. Hence option B is correct.

What is the  Azure AD tenant?

An administrative unit is a container object in Azure Active Directory (Azure AD) that you can use to organize and manage users, groups, and devices. You can use administrative units to delegate administrative tasks, such as creating and managing users, to specific users or groups.

By assigning User1 to an administrative unit that contains the users from the Marketing department only, you can ensure that User1 can manage only those users and not the users from the Human Resources department.

Note that Management groups, Custom Azure AD roles, and Security groups that use dynamic user membership are other Azure resources but are not appropriate for this scenario because they don't provide the ability to delegate administrative tasks to specific users or groups and define a scope of management.

Answers

In data science, dealing with missing values—either by removing them or imputed values—is crucial (handling them with some estimation)

what is strategy for dealing with missing data?

An additional effective method for managing the missing data is multiple imputation. In a multiple restoration, the lost numbers are replaced with a collection of probable values that include the inherent uncertainty and variability of the correct values rather than replacing each missing value with a single value. This method starts by predicting the incomplete information using the information already available for the other variables [15]. The imputed data set, which is a complete data set, is then constructed by replacing the missing values with the projected values. This procedure creates numerous imputed data sets and iterates the repeatability (hence the term "multiple imputation"). Each multi imputed data set generated is thereafter subjected to the same statistical analysis as complete data, yielding results for numerous analyses.
