Hi, I have a CodeHS Python assignment called "Exclamation Points"


the assignment is as follows and I have no idea where to start with this if someone could help me please:


"Words are way more edgy when you replace the letter i with an exclamation point!


Write the function exclamations that takes a string and then returns the same string with every lowercase i replaced with an exclamation point. Your function should:


Convert the initial string to a list

Use a for loop to go through your list element by element

Whenever you see a lowercase i, replace it with an exclamation point in the list

Return the stringified version of the list when your for loop is finished"

Below is a simple flowchart that shows the process of calculating the volume of an object using its mass and density:

       +-----------------------------+

       |     Input: Mass (m),        |

       |     Density (d)             |

       +-----------------------------+

                |

                |

       +-----------------------------+

       |   Volume = Mass / Density   |

       +-----------------------------+

                |

                |

       +-----------------------------+

       |    Output: Volume (v)       |

       +-----------------------------+

The flowchart I provided shows the basic process of calculating the volume of an object using its mass and density. The process starts with the input of the object's mass and density. The mass is typically given in grams and the density is given in grams per cubic centimeter.

The next step is to calculate the volume of the object. This is done by using the formula for density, which states that density is equal to mass divided by volume. So, to find the volume, we divide the mass of the object (in grams) by its density (in grams per cubic centimeter). This formula can be written as:

volume = mass / density

Finally, the calculated volume is then output, which is typically given in cubic centimeters.

Note that:

density = mass/volume.

Density = mass / volume

Explanation:

The biggest question now is how do we attract more women into the computer science field. Women need more encouragement, especially from teachers of both sexes and fellow students. Mentoring is a definite means to attract and keep women more interested in the field. Even just the support of other females present in a classroom setting can help boost the confidence in each other. Multiple studies have shown that the lack of women in computer science is very likely to start before college (Cohoon). They need this encouragement not only while taking college courses but also early on in their education. Females tend to be just as interested in science as men when they are young but their teachers and schools, who would have the most influence on them, aren’t doing their job in nurturing and identifying these women (Gurian). A possible solution to improving their confidence would be to have more mentors who can help attract and keep women interested in the field. The shortage of women in the computer science field has made it more difficult to have women in high positions. This makes it important for women who are in high positions to be mentors to all women interested. According to Joanne Cohoon a professor at the University of Virginia “CS departments generally retained women at comparable rates to men when the faculty included at least one woman; was mentored, and supervised female students; enjoyed teaching; and shared responsibility for success with their students”. It is also found that departments with no female faculty lost female students at high rates relative to men (Cohoon). Seeing other women in computer science can definitely raise confidence in women to continue or begin studying the subject. “In a new survey, 40 percent of women in the STEM fields… report that they were discouraged from their career choices, typically in college and often by their professors” (Downey). This data shows how we need more mentors willing to support women and that we are lacking teachers to help inspire young women into entering the field.

Since the beginning of computing most software and programs have been male-oriented. Video games were originally targeted at males with sport and violent themes with mostly male lead characters and limiting female roles like women who need to be rescued (Lynn). Early experiences with computers are important in shaping someone’s willingness to explore technology. “Playing with computer, console, and arcade games and educational ware can provide an introduction to computer literacy, creating familiarity and building confidence in skills” (Lynn, 145). Because computer science is so dominated by men, the software tends to be more male- friendly. To make software more appealing to girls, it should have low frustration levels, be challenging and be interactive (Lynn). By having more women in the field, women can create much more women-friendly software. Girls tend to prefer games where they can make things, rather than destroy them(Lynn). Recently more and more games have been produced that are more girl-friendly, like simulation games. The Sims is a video game where you create humans, animals and homes and has proved to be a big success with a female audience. A strategy to get more women to break outside the stereotype of women being less competitive than men would be to take games designed for boys and demand comparable female characters to empower them to be more competitive and assertive. Video games often become involved with computing as a byproduct of wanting to master gaming (Lynn).

Many boys tend to have more experience with computers at a younger age because of video games, when boys and girls are put together in a class to learn about computers the boys are already at a higher level, which is not encouraging to the women beginning at a lower level in the same class. Making more computer classes mandatory both in high school and at the college level will not only help women because of the increasing number of other female peers, but it can spark interest in women early on, helping teachers to identify students with aptitude.

Here is an implementation of the safe_normalize function that catches the error and returns the original list if an error occurs:

def safe_normalize(lst):

try:

return normalize(lst)

except ZeroDivisionError:

return lst

This function calls the normalize function, which takes a list as input and returns a normalized list. However, if an error occurs (in this case, a ZeroDivisionError), the function will catch the error and return the original list instead.

To test the safe_normalize function, you can use the following test cases:

print(safe_normalize([1, 2, 2, 3])) # Expected output: [0.125, 0.25, 0.25, 0.375]

print(safe_normalize([1, 2, -5, 2])) # Expected output: [1, 2, -5, 2]

The first test case should return the normalized list, while the second test case should return the original list, since the normalize function would fail with a ZeroDivisionError if passed a list with a negative sum.

Here is some pseudocode that outlines the steps for creating a program that calculates overall final marks and outputs the necessary grades for a desired overall mark:

DEFINE a function called "calculate_final_mark"

INPUT: grades (list), weights (list), desired_mark (float)

CREATE a variable called "overall_mark" and set it to 0

FOR each grade and weight in the grades and weights lists:

 MULTIPLY the grade by the weight

 ADD the result to the overall_mark

IF overall_mark equals the desired_mark:

 OUTPUT "You have already achieved the desired mark."

ELSE:

 CREATE a variable called "needed_mark" and set it equal to the desired_mark minus the overall_mark

 OUTPUT "You need a" needed_mark "on your next assessment to achieve a" desired_mark "overall mark."

END the function

Here is the equivalent code in Python:

def calculate_final_mark(grades, weights, desired_mark):

 overall_mark = 0

 for grade, weight in zip(grades, weights):

   overall_mark += grade * weight

 if overall_mark == desired_mark:

   print("You have already achieved the desired mark.")

 else:

   needed_mark = desired_mark - overall_mark

   print(f"You need a {needed_mark} on your next assessment to achieve a {desired_mark} overall mark.")

To design a simple network for Maendeleo Institute of Technology with 240 employees, we could use a combination of routers, switches, and hubs.

Our network would consist of five separate networks, one for each department at the institute. We would use class C IP addresses, with a subnet mask of /24, to create the following subnets:

Computer Science department: 192.168.10.0/24

Information Technology department: 192.168.11.0/24

Account department: 192.168.12.0/24

Human Resource department: 192.168.13.0/24

Marketing department: 192.168.14.0/24

Each department would be connected to the network via a switch, which would allow for communication within the department and with other departments as needed. A router would be used to connect the individual department networks to the wider internet, and would also serve as a firewall to protect the network from external threats.

We would also include a hub in the network to allow for communication between devices within a department, as well as to provide additional connectivity and scalability.

Overall, our network design would provide each department with its own separate network, with the ability to communicate with other departments as needed. It would also be scalable, allowing for the addition of new devices and departments as the institute grows. The use of class C IP addresses and a /24 subnet mask would ensure that IP addresses do not overlap, ensuring efficient and reliable communication within the network.

Since Grayson uses a program that allows him to keep track of how much money he earns and spends each week. The type of data that will be used to give him the answer to the question is option A: "Boolean".

A Boolean variable can hold only two values: true or false.

He can use a conditional statement to check if the amount of money he has left over after subtracting his expenses from his earnings is greater than or equal to the cost of the ice cream. If it is, he can set the Boolean variable to "True", indicating that he has enough money for ice cream. If it is not, he can set the Boolean variable to "False", indicating that he does not have enough money.

Therefore, Grayson can compare the value of his remaining money to the cost of the ice cream, if the remaining money is greater than or equal to $4, he can set the Boolean variable to "True" which means he has enough money.

This solution first generates all possible permutations of the digits 0-9 using the permutations function from the itertools module. Then, it iterates through each permutation and creates a dictionary mapping each alphabet to a digit. It checks if the leftmost letter in any word is not zero and if the sum of the numbers is equal to the last argument. If both conditions are satisfied, it returns the mapping. If no solution is found after iterating through all permutations, it returns False.
