7.4 Code Practice: Question 2
Adjust the code you wrote for the last problem to allow for weighted classes. Add a parameter weighted ( 1 = yes, 0 = no) and then return the correct number for the GPA. Weighted classes get one extra point on the GPA value.
I could really use some help on this and 7.5 (I’ll ask that question for 7.5 later)
def GPAcalc(grade, weighted):
grade = grade.lower()
dictionary = {"a": 4, "b": 3, "c": 2, "d": 1, "f": 0}
if weighted == 1 and grade in dictionary:
return "Your GPA score is: "+str(dictionary[grade] + 1)
elif weighted == 0 and grade in dictionary:
return "Your GPA score is : "+str(dictionary[grade])
else:
return "Invalid"
print(GPAcalc(input("Input a letter grade: "), int(input("Is it weigthed? (1= yes, 0= no)"))))
I modified the code a bit to cut down on the use of if and elif statements. If you need me to change it, I will. Best of luck.
The program is an illustration of conditional statements.
Conditional statements are statements whose execution is dependent on its truth value.
The program in Python, where comments are used to explain each line is as follows:
#This initializes the dictionary
dict = {"a": 4, "b": 3, "c": 2, "d": 1, "f": 0}
#This gets input for grade
grade = input().lower()
#This gets input for the weighted average
weighted = int(input())
#If the weighted average is 1, and the grade is in the dictionary
if weighted == 1 and grade in dictionary:
#This prints the GPA score
print("Your GPA score is: "+str(dict[grade] + 1))
#If the weighted average is 0, and the grade is in the dictionary
elif weighted == 0 and grade in dictionary:
#This prints the GPA score
print("Your GPA score is : "+str(dict[grade]))
#Otherwise
else:
#The grade is invalid

The __________ holds the data in the HDFS and the application connects with the __________ to send and retrieve data from the cluster.
The DataNode holds the data in the HDFS, and the application connects with the NameNode to send and retrieve data from the cluster.
The Hadoop Distributed File System (HDFS) is a distributed file system that stores data across multiple machines in a Hadoop cluster. In HDFS, data is divided into blocks and replicated across several nodes in the cluster for fault tolerance. The component that holds the data in the HDFS is called the DataNode. Each DataNode is responsible for storing data in its local file system and serving read and write requests from clients. When a client wants to read or write data, it communicates with the DataNode that has a copy of the data. The component that the application connects to send and retrieve data from the HDFS is called the NameNode. The NameNode is the master node in the HDFS that manages the file system namespace and the metadata about the data stored in the cluster. The NameNode keeps track of which blocks of data are stored on which DataNodes and coordinates data access requests from clients.

Explanation:
What might happen to the wire if the uneven load is never balanced
If an uneven load on a wire is never balanced, it can lead to a variety of potential problems and risks. One of the most common consequences of uneven loading is the buildup of stress and tension in the wire, which can cause it to become overstretched and potentially snap or break.
When a wire is subjected to uneven loading, such as when a heavier weight is placed on one side of the wire than the other, the tension in the wire becomes unbalanced. This can cause the wire to become stretched beyond its normal limits, which can lead to deformation, fatigue, and ultimately failure. If the wire is not balanced, it may also be more susceptible to external factors such as wind, vibration, and temperature changes, which can exacerbate the stress and strain on the wire.
In addition to the risk of wire failure, uneven loading can also lead to other safety hazards. For example, if the wire is used to support a structure or equipment, an imbalance in the load can cause the structure to become unstable or the equipment to malfunction. This can result in property damage, injuries, and even loss of life.
To prevent these types of issues, it is important to ensure that loads are evenly distributed on wires and other support structures. This can be achieved through the use of proper rigging techniques, such as the use of equalizer bars or spreader bars, and by carefully monitoring loads to ensure that they are balanced at all times. By taking these precautions, the risk of wire failure and other safety hazards can be minimized.

A camera detector has an array of 4096 by 2048 pixels and uses a colour depth of 16.
Calculate the size of an image taken by this camera; give your answer in MiB.
The size of an image taken by this camera is approximately 16 MiB.
How to calculate the size of an image?To calculate the size of the image taken by the camera, we need to know the total number of bits in the image.
The number of pixels in the image is:
4096 pixels × 2048 pixels = 8,388,608 pixels
The colour depth is 16, which means that each pixel can be represented by 16 bits. Therefore, the total number of bits in the image is:
8,388,608 pixels × 16 bits per pixel = 134,217,728 bits
To convert bits to mebibytes (MiB), we divide by 8 and then by 1,048,576:
134,217,728 bits ÷ 8 bits per byte ÷ 1,048,576 bytes per MiB = 16 MiB (rounded to two decimal places)

The Student model in Django has a primary key student_id, which is an auto-incrementing integer, and student_name, a variable-length character field with a maximum length of 30 characters. This model will create a database table to store student information in a structured manner.
In Django, a model represents a database table and defines its structure. To create a Student model, you would define a class in your Django app's models.py file, inheriting from the Django's Model class. The Student model will have two attributes: student_id and student_name, with specific constraints.
Here's the model definition:
```python
from django.db import models
class Student(models.Model):
student_id = models.AutoField(primary_key=True)
student_name = models.CharField(max_length=30)
```
In this model, student_id is an auto-incrementing integer field, created using AutoField. It is set as the primary key for the Student model by adding the parameter primary_key=True. The student_name attribute is defined using CharField, a field for storing variable-length strings. The max_length parameter is set to 30, indicating the maximum number of characters allowed for student_name.

1. Difficulties identifying what distal stimuli produce what proximal stimuli
The difficulty in identifying what distal stimuli produce what proximal stimuli refers to challenges in determining the relationship between the external, environmental stimuli (distal stimuli) and the internal, sensory stimuli (proximal stimuli) they generate.
In perception and sensory processing, distal stimuli are the external objects or events present in the surrounding environment, while proximal stimuli are the sensory information received by our sensory organs (e.g., vision, hearing) as a result of interacting with those distal stimuli.Identifying the exact correspondence between distal stimuli and proximal stimuli can be complex due to various factors such as the complexity of the sensory systems, individual differences in perception, and the potential influence of contextual information. For example, different distal stimuli can sometimes produce similar proximal stimuli, or a single distal stimulus can result in different proximal stimuli based on individual perception.

5. your network design calls for 50 subnets with a maximum of 200 hosts per subnet. you are assigned a class b network. what subnet masks meet these requirements? which mask maximizes the number of subnets? which mask maximizes the number of hosts?
1. Subnet masks meeting the requirements: 255.255.252.0
2. Subnet mask maximizing the number of subnets: 255.255.255.0
3. Subnet mask maximizing the number of hosts: 255.255.192.0
To determine the subnet masks that meet the requirements, maximize the number of subnets, and maximize the number of hosts, we need to consider the given parameters and perform subnetting calculations.
Given parameters:
- Number of subnets required: 50
- Maximum number of hosts per subnet: 200
- Assigned network class: Class B network
For a Class B network, the default subnet mask is 255.255.0.0, which provides a maximum of 16,384 \((2^14)\) possible subnets and 65,534 (2^16 - 2) possible hosts per subnet. However, this default mask does not meet the given requirements.
1. Subnet masks meeting the requirements:
To meet the requirement of 50 subnets and a maximum of 200 hosts per subnet, we need to find a subnet mask that provides enough bits for both subnets and hosts. Since 50 subnets require at least 6 bits \((2^6 =\)64), and 200 hosts require at least 8 bits \((2^8 - 2 = 254)\), we can use a subnet mask with 14 bits for subnets and 8 bits for hosts: 255.255.252.0.
2. Subnet mask maximizing the number of subnets:
To maximize the number of subnets, we need to use the minimum number of bits for hosts and allocate the remaining bits for subnets. In this case, we can use a subnet mask with 8 bits for subnets and 8 bits for hosts: 255.255.255.0. This provides a maximum of 256\((2^8)\) possible subnets.
3. Subnet mask maximizing the number of hosts:
To maximize the number of hosts per subnet, we need to use the minimum number of bits for subnets and allocate the remaining bits for hosts. In this case, we can use a subnet mask with 18 bits for subnets and 14 bits for hosts: 255.255.192.0. This provides a maximum of 16,382 (2^14 - 2) possible hosts per subnet.
