Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.
Lists are used in Python to hold multiple values in one variable
(a) Nested list
A nested list is simply a list of list; i.e. a list that contains another list.
It is also called a 2 dimensional list.
An example is:
nested_list = [[ 1, 2, 3, 4] , [ 5, 6, 7]]
(b) The “*” operator
The "*" operator is used to calculate the product of numerical values.
An example is:
num1 = num2 * num3
List slices
This is used to get some parts of a list; it is done using the ":" sign
Take for instance, you want to get the elements from the 3rd to the 5th index of a list
An example is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
secondList = firstList[2:5]
The “+=” operator
This is used to add and assign values to variables
An example is:
num1 = 5
num2 = 3
num2 += num1
A list filter
This is used to return some elements of a list based on certain condition called filter.
An example that prints the even elements of a list is:
firstList = [1, 2 ,3, 4, 5, 6, 7]
print(list(filter(lambda x: x % 2 == 0, firstList)))
A valid but wrong list operation
The following operation is to return a single list, but instead it returns as many lists as possible
def oneList(x, myList=[]):
myList.append(x)
print(myList)
oneList(3)
oneList(4)

Professor Gekko has always dreamed of inline skating across North Dakota. He plans to cross the state on highway U.S. 2, which runs from Grand Forks, on the eastern border with Minnesota, to Williston, near the western border with Montana. The professor can carry two liters of water, and he can skate m miles before running out of water. (Because North Dakota is relatively flat, the professor does not have to worry about drinking water at a greater rate on uphill sections than on flat or downhill sections.) The professor will start in Grand Forks with two full liters of water. His official North Dakota state map shows all the places along U.S. 2 at which he can refill his water and the distances between these locations. The professor’s goal is to minimize the number of water stops along his route across the state.
a. Give an efficient algorithm by which he can determine which water stops he should make.
b. Prove that your strategy yields an optimal solution, and give its
The efficient algorithm by which he can determine which water stops he should make; has been determined below and the strategy which is the greedy strategy has been proven to yield an optimal solution.
To solve this question optimally, we will make use of the greedy solution.
In this method, we will maximize the distance that can be covered from a particular point in such a way that there must be a place where water can be gotten before a run out is experienced.
Now, the first point at which there will be a stop should be located at a point that is farthest from the starting position and is also made to be ≤ m miles from the starting position.
Now, this this situation is one that shows optimal substructure and since our first stopping point will be made to be at p, it means that we are solving the sub-question with the assumption that our starting point is at p.
When we combine the two stated plans above, we will arrive at an optimal solution for the normal reasons via cut and paste.
B) Now we need to show that the greedy approach earlier used produce a first stopping point which is contained in the optimal solution.
Let O represent any optimal solution whereby the professor stops at positions o₁, o₂, o₃....oₙ.
Let h₁ represent the farthest stopping point that is reachable from the starting point. Then we can replace o₁ by h₂ to generate a modified solution H since o₁ - o₂ < o₂ - h₁.
Finally, we can really make it to the positions in H without having to run out of water and since H has the same number of stops, we can conclude that h₁ is contained in one of optimal solution.
Therefore our strategy which is the greedy strategy has been proven to work.

Answer:
num1 = int(input("Enter value: "))
num2 = int(input("Enter value: "))
if num1 == num2:
print("Equals.")

print("Unequal.")
Explanation:
The Boolean expression that tests if the value stored in the variable num1 is equal to the value stored in the variable num2 can be found in explanation.
What is boolean expression?A logical statement that could be either true or false is referred to as a Boolean expression.
As long as both parts of the expression have the same basic data type, Boolean expressions can compare data of any type. Data can be tested to see if it is the same as, greater than, or less than other data.
A Boolean expression is a type of expression used in programming languages that produces a Boolean value when evaluated. A Boolean value can only be true or false.
The boolean expression for the given scenario can be:
num1 = int(input("Enter value: "))
num2 = int(input("Enter value: "))
if num1 == num2:
print("Equals.")
else:
print("Unequal.")
