Create your own Python code examples that demonstrate each of the following. Do not copy examples from the book or any other source. Try to be creative with your examples to demonstrate that you invented them yourself.
Example 1: Define a function that takes an argument. Call the function. Identify what code is the argument and what code is the parameter.
Example 2: Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identify which kind of argument is which.
Example 3: Create a function with a local variable. Show what happens when you try to use that variable outside the function. Explain the results.
Example 4: Create a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results.
Example 5: Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs

Example 1:
def greet(name):
print("Hello,", name)
greet("John")
In this example, the function greet takes one argument, which is the variable name. When we call the function and pass in the argument "John", the function prints out Hello, John. The code "John" is the argument, and name is the parameter.
Example 2:
def greet(name):
print("Hello,", name)
greet("John")
greet("Mary")
x = "Alice"
greet(x)
greet("Hi " + x)
In this example, we call the function greet three times with different kinds of arguments. "John" and "Mary" are values, x is a variable, and "Hi " + x is an expression.
Example 3:
def some_function():
x = 5
print(x)
In this example, we define a function some_function that has a local variable x. When we try to print out the value of x outside of the function, we get a NameError because x is not defined in that scope.
Example 4:
def greet(name):
print("Hello,", name)
greet("John")
print(name)
In this example, we define a function greet that takes an argument name. When we try to print out the value of name outside of the function, we get a NameError because name is a local variable that only exists within the scope of the greet function.
Example 5:
x = 10
def some_function():
x = 5
print("Inside function:", x)
some_function()
print("Outside function:", x)
In this example, we define a global variable x and a function some_function that has a local variable x. When we call some_function, it prints out the value of x as 5, which is the value of the local variable. When we print out the value of x outside of the function, it prints out 10, which is the value of the global variable. The local variable x inside the function and the global variable x outside the function are different variables with different values.
In this code, we first define a function called `rotate` that takes three arguments, `a`, `b`, and `c`. Inside the function, we create a tuple with the values of `c`, `a`, and `b`, in that order.
```
def rotate(a, b, c):
return (c, a, b)
a, b, c = 'Doug', 22, 1984
result1 = rotate(a, b, c)
a, b, c = result1
print(a, b, c)
result2 = rotate(a, b, c)
a, b, c = result2
print(a, b, c)
result3 = rotate(a, b, c)
a, b, c = result3
print(a, b, c)
```
Next, we define three variables, `a`, `b`, and `c`, with the values 'Doug', 22, and 1984, respectively.
Then, we call the `rotate` function three times, each time passing in `a`, `b`, and `c` as arguments. We store the result of each function call in a separate variable (`result1`, `result2`, and `result3`).
Finally, we unpack the result of each function call into `a`, `b`, and `c`, and display their values using the `print` function.
When you run this code, you should see the following output:
```
1984 Doug 22
22 1984 Doug
Doug 22 1984
```

Using a Telephoto Lens to Capture a Narrow Field of View at 90 FeetA telephoto lens is ideal for capturing a narrow field of view when the subject is far away. By using a telephoto lens, the subject can be zoomed in on and captured with greater detail. This type of lens has a longer focal length than a wide angle lens, which allows it to capture a narrower field of view while still maintaining a sharp image. It also has the ability to capture distant subjects with greater clarity and depth of field.

which type of attack is wep extremely vulnerable to?
Answers
WEP is extremely vulnerable to a variety of attack types, including cracking, brute-force, IV (Initialization Vector) attack, and replay attack.
What is Initialization Vector?An Initialization Vector (IV) is a random number used in cryptography that helps to ensure the uniqueness and randomness of data used in an encryption process. The IV is typically used as part of an encryption algorithm, where it is combined with a secret key to encrypt a message. The IV is unique for each encryption session, and must be unpredictable and non-repeating. A good IV should not be reused across multiple encryption sessions, and it should be kept secret from anyone who does not have access to the decryption key. Without a good IV, a cryptographic system can be vulnerable to attacks such as replay attacks, where an attacker can gain access to the system by repeating an encrypted message.
