Choose the 3 correct statements for the code below.
An object of the ActivationLayer class has a name attribute.
An object of the BaseLayer class has a size attribute.
print(FCLayer(42)) prints FullyConnectedLayer.
When creating an object of the ActivationLayer class, the size argument must be given.
When creating an object of the BaseLayer class, the name argument must be given.
Answer:
True
False
True
False
True
Explanation:
So I'll go through each statement and explain why or why not they're correct.
An object of the ActivationLayer class has a name attribute. So because ActivationLayer is inheriting the BaseLayer and it's calling super().__int__("Activation") it's going to call the BaseLayer.__init__ thus setting a name attribute equal to "Activation" for any ActivationLayer object that is initalized. So this is true
An object of the BaseLayer class has a size attribute. While it is true that FC layer is inheriting from BaseLayer and it has a size attribute, this does nothing to change the BaseLayer class. So any object initialized to a BaseLayer object will only have the instance attribute "self.name". So this is false
print(FCLayer(42)) prints FullyConnectedLayer. So whenever you print an object, it tries to convert the object to a string using the __str__ magic method, but if that wasn't defined it then tries the __repr__ method, which the FCLayer class technically doesn't define, but it inherits it from the BaseLayer class. And since whenever you define an FCLayer object it calls super().__init__ with "FullyConnected", which will then be assigned to the instance variable self.name, it will print "FullyConnectedLayer". So this is true
When creating an object of the ActivationLayer class, the size argument must be given. This is true, because the size is a parameter of the __init__ method of ActivationLayer, it is not an optional parameter, and is something that must be passed otherwise an error will be raised. So this is false
When creating an object of the BaseLayer class, the name argument must be given. This is not true, because name is a default argument. This means if you do not pass an argument for name, then name will equal an empty string

2.16 LAB: Port Scan (Modules)
In network security, it is important to understand port scanning. Hackers use tools to scan a network and determine if there are open ports and if they contain some sort of vulnerability. To scan ports, you first have to find active hosts on a network. Once you find active hosts and discover a list of IP addresses for those hosts, a port scan can be performed to gather information about open ports and analyze services running on those ports. A port scan is the process of sending packets to an active host's ports and learning details that can help you gain access to that host or to discover open vulnerabilities on your network.
Some common ports are:
Port 20 - File Transfer Protocol or FTP
Port 22 - Secure Shell protocol or SSH
Port 23 - Telnet protocol for unencrypted transfer
Port 80 - HyperText Transfer Protocol or HTTP
Port 443 - HyperText Transfer Protocol Secure or HTTPS
The Well Known Ports are those from 0 through 1023
We are going to simulate a port scan by filling a list with 100 random port numbers. These values will be used as the keys in a dictionary where the values will be randomly generated integers 0 / 1. The 0 will be a closed port and a 1 will be an open port.
Your first TODO is to create a function called "create_host_IPs( )" that randomly generates a list of 10 IP addresses with 4 random octets values, concatenating the 4 values into a string and appending it to a host list. The function returns the generated host list. The random values can be limited to a range of 10 to 200.
Ex: IPv4 address should look like this:
192.168.34.23
Your next TODO is to create another function called "simulate_scan(h)" that iterates through the host list (received as h ) and then creates a new list called open_ports. The function should use a nested for loop that iterates through the host list, and then iterates through the returned list from a call to "create_random_open_ports()". If the returned list value is 1, then append it to your open_ports list. This simulates a scan of all the IPs in the host list and creates randomly generated open ports. Finally it should print the host IP and a list of open ports as displayed in this example output.
Ex: Your output should contain 10 IP reports. Here is and example of 2 of the 10 reports:
Host IP: 66.78.126.11
Open ports are:
[53, 87, 21, 57, 71, 37, 61, 38, 45, 94, 84, 26, 72, 52, 75, 41, 90, 88, 82, 59, 50, 36, 60, 16, 51, 76, 24, 66, 33, 63, 86, 93, 34, 85]
Host IP: 11.96.129.20
Open ports are:
[15, 77, 19, 72, 78, 37, 93, 42, 26, 30, 79, 16, 47, 48, 43, 50, 82, 60, 46, 10, 62, 96, 12, 99, 76, 51, 32, 24, 61, 87, 73, 65, 85, 67, 29]

For example, we have an integer variable a to which holds a value 10. if you want to read the address of the variable a, use &a. To store this address in any other memory declare a pointer variable.
int a = 10;
int *loc_a;
loc_a = &a;
