The SQL keyword that creates a query is "SELECT". It is used to select data from one or more tables and return a result set.
In SQL, the SELECT keyword is used to retrieve data from a database. It is followed by one or more columns or expressions that specify the data to be retrieved, and one or more tables from which the data will be retrieved. The result set is returned as a table with rows and columns that match the selected data. The SELECT keyword can be combined with other keywords, such as FROM, WHERE, GROUP BY, HAVING, ORDER BY, and LIMIT, to perform more complex queries. Overall, the SELECT keyword is the backbone of SQL queries and is used in almost every query.

How to solve "upstream prematurely closed connection while reading response header from upstream"?
Answer:
"Upstream prematurely closed connection while reading response header from upstream" is an error message that can occur when there is a problem with communication between a web server and an upstream server. This can happen for a variety of reasons, including issues with the network connection, problems with the upstream server, or issues with the web server's configuration.
Here are some steps you can try to troubleshoot this error:
Check the network connection: Make sure the network connection between the web server and the upstream server is stable and not experiencing any issues.
Check the upstream server: If the upstream server is experiencing problems or is offline, it may be causing the error. You can try restarting the upstream server or checking its logs for more information.
Check the web server's configuration: Make sure the web server is properly configured to communicate with the upstream server. This may involve checking the web server's configuration files and ensuring that the correct hostname and port are specified for the upstream server.
Check for any error messages in the web server's logs: The web server's logs may contain additional information about the cause of the error.
Check for any system-level issues: If you are using a load balancer or other system-level software, it may be causing the error. You can try restarting or reconfiguring these systems to see if that resolves the issue.
It's also a good idea to check the documentation for the web server and the upstream server to see if there are any known issues or configuration changes that may be causing the error.

2. In many jurisdictions a small deposit is added to containers to encourage people to recycle them. In one particular jurisdiction, containers holding one litre or less have a $0.10 deposit, and containers holding more than one litre have a $0.25 deposit. Write a Python script that reads the number of containers of each size from the user. The script should compute and display the refund that will be received for returning those containers. Format the output so that it includes a dollar sign and displays exactly two decimal places.
Answer:
Here is the Python program:
small_container = int(input("Enter the number of small containers you recycled?"))
large_container = int(input("Enter the number of large containers you recycled?"))
refund = (small_container * 0.10) + (large_container * 0.25)
print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund)))
Explanation:
The program first prompts the user to enter the number of small containers. The input value is stored in an integer type variable small_container. The input is basically an integer value.
The program then prompts the user to enter the number of large containers. The input value is stored in an integer type variable large_container. The input is basically an integer value.
refund = (small_container * 0.10) + (large_container * 0.25) This statement computers the refund that will be recieved for returning the small and larger containers. The small containers holding one litre or less have a $0.10 deposit so the number of small containers is multiplied by 0.10. The large containers holding more than one litre have a $0.25 deposit so the number of large containers is multiplied by 0.25. Now both of these calculated deposits of containers of each side are added to return the refund that will be received for returning these containers. This whole computation is stored in refund variable.
print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund))) This print statement displays the refund in the format given in the question. The output includes a $ sign and displays exactly two decimal places by using {0:.2f} where .2f means 2 decimal places after the decimal point. Then the output is represented in floating point number using. format(float) is used to specify the output type as float to display a floating point refund value up to 2 decimal places.
The required code which calculates the amount of refund made by returning the containers written in python 3 goes thus :
small_size = eval(input('Enter number of 1L or less containers to be returned: '))
#prompts user to enter the number of small sized containers to be returned
big_size = eval(input('Enter number of containers greater than 1L to be returned: '))
#prompts user to enter the number of big size containers to be returned
small_refund = (small_size * 0.10)
#calculates the total refund on small sized containers
big_refund = (big_size * 0.25)
# calculates the total refund on big size containers
total_refund = float((small_refund + big_refund))
#calculates the Cummulative total refund
print('Your total refund is $' + '{0:.2f}'.format(total_refund))
#displays the total refund rounded to 2 decimal places.

How can we use sprites to help us keep track of lots of information in our programs?
Sprites solve the problem of organizing a lot of information about how something should be drawn to a screen. Rather than creating new variables to hold all of that information, sprites use properties to hold all of the information about one thing that is drawn to the screen.
Explanation:
A sprite in Scratch is an image that may be made to move, react to triggers, and communicate with other sprites. Sprites can be imported from files on your computer or made from scratch. After a sprite has been made, you can assign it scripts, outfits, and noises.
What is the role of sprites in track of lots of information?Sprites employ properties to store all the data about a single object that is drawn to the screen, rather than generating separate variables to keep all of that data.
A “stand-alone” computer graphic element known as a “sprite” has developed alongside more recent computer graphics technologies.
A two-dimensional picture or animated image known as a sprite performs a specific function and is frequently independently modified within a wider visual environment.
Therefore, we use sprites to help us keep track of lots of information in our programs.

You wrote a program to allow the user to guess a number. Complete the code.
while keepGoing:
guess = input("Guess an integer from 1 to 10: ")
guess = int(guess)
attempts = attempts + 1
if guess == correct:
print("You were correct!")
keepGoing = ______
else:
if guess < correct:
print("Guess higher.")
else:
print("Guess lower. ")
Answer:
The complete program is as follows:
keepGoing = True
attempts = 0
correct = 2
while keepGoing:
guess = input("Guess an integer from 1 to 10: ")
guess = int(guess)
attempts = attempts + 1
if guess == correct:
print("You were correct!")
keepGoing = False
elif guess < correct:
print("Guess higher.")
else:
print("Guess lower. ")
Explanation:
This line initializes keepGoing to true
keepGoing = True
This initializes number of attempts to 0
attempts = 0
This initializes the correct guess to 2 (you can also use any number)
correct = 2
The following iteration is repeated until the number is guessed correctly
while keepGoing:
guess = input("Guess an integer from 1 to 10: ")
guess = int(guess)
attempts = attempts + 1
if guess == correct:
print("You were correct!")
If user guess is correct, keepGoing is set to False
keepGoing = False
