What is Python?
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the second-most popular programming language

How does this code give me 17? (python)
j = 3
z = {}
z[2] = 1
z[7] = 3
z[5] = 2
for l in z:
j += l
print(j)
I don't understand where the 17 is coming from. I thought the square brackets were basically accessing the location (meaning the code would be like this "1, 2, 3." I even thought of individually adding 3 separately to all the numbers only for it to give me 15. Yeah, i've trying to understand this for 2 days lol.
Answer:
See explanation below and try out this code to see what exactly is happening
# Program
j = 3
z = { ] # empty dictionary
print(z)
z[2] = 1 # z
print(z)
z[7] = 3
print(z)
z[5] = 2
print(z) # prints out {2: 1, 7: 3, 5: 2}
for l in z:
print("Initial value of j = ", j)
print("Value of l(key) = ", l)
j += l
print("Updated value of j = ", j)
print("Final value of j=", j)
Explanation:
What you have is a dictionary object. We use { } to represent a dictionary. A dictionary consists of keys and values related to the keys. For example, you can have a dictionary which contains names of students and their GPAs
This is declared as
student_grades = {"Amy": 4.3, "Zach":4.0", "Bill": 3.2}
The names are referred to as keys and the GPA as values
You can also have both key and value as integers. Fir example you could store the cubes of numbers from 1 to 5 in a dictionary
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125}
If you wanted to add the cube for 6 then you would use cubes[6] = 216 This creates a new entry in the dictionary 6:216 so that the dictionary is now
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125, 6:216}
In this short program here is what is happening
j = 3 # variable j created and value set to 3
z = { } # this creates an empty dictionary named z
z[2] = 1 #adds an entry with key = 2 and value = 1; z = {2 : 1}
z[7} = 3 #key 7 and value 2 added => z = {2 : 1, 7 : 3}
z[5] = 2 #key 5, value 2 => z = {2: 1, 7 : 3, 5 : 2}
So now there are 3 entries in the dictionary i.e. 3 pairs of key-values
When you iterate through the dictionary as in
for l in z:
- you are actually iterating over the keys so l = 2, 7 and 5 on each iteration
So you are accumulating the key values
Here is what happens
First execution of loop => j = 3 , l = 2 (first key =2), j = 3 + 2 = 5
Second time: l = 7 (second key value) , j = 5 + 7 = 12
Third time: l = 5, j = 12 + 5 = 17
There is a lot more to dictionaries and sometimes it can get complicated. Suggest you search the internet for the same
Putting print() statements also helps you visualize what is happening. Code is provided in the answer section to help you

How is blockchain different from traditional database models?
Blockchain can lead to increased transparency and trust in data, ultimately driving more innovation, improved productivity, and quality.
Blockchain prohibits transparency by redefining the fundamental nature of business ecosystems and business flows.
Blockchain provides multiple versions of the data that can be kept by individual entities.
Blockchain increases innovation; however, it decreases productivity and quality.
I don't know this yet.
The difference between blockchain and traditional database models is that: C. Blockchain provides multiple versions of the data that can be kept by individual entities.
What is a database?A database simply refers to an organized and structured collection of data that're stored on a computer system as a backup and they're usually accessed electronically.
What is a blockchain?A blockchain can be defined as a digital and dynamic financial system that is designed and developed to be used in recording and maintaining transactions that are associated with or made through the use of a bitcoin, usually as a database.
In this context, we can infer and logically deduce that unlike the traditional database models, blockchain is designed and developed to provide multiple versions of financial transactions (data), and they can also be kept by individual business entities.

In this lab, you complete a partially written C++ program that includes a function that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, -, *, or / ). The two numbers and the operator are passed to the function where the appropriate arithmetic operation is performed. The result is then returned to the main() function where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3 * 4 = 12
The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program.
Instructions
1. Write the C++ statements as indicated by the comments.
