Why create an algorithm?

Because computers are better at solving problems.
Computers aren’t necessarily better at solving problems, though often they can be quicker than humans. Additionally, algorithms can be used to solve non-computer related problems.
So that you don’t have to solve the problem yourself.
While it is beneficial to have a set of instructions that others can follow, this isn’t the best answer. By creating the algorithm, you solve a problem for yourself and others.
So that you have a general solution to a problem.
Yes, by creating a general solution you can then express it as a program if you choose, and then use a computer to automate the execution.
Because you need a set of instructions to follow.
While it is beneficial to have a set of instructions as that is what an algorithm **is**, it is not **why** we would want to create one.

Write code to print out the phrase “Hello World”.

What will be output to the console when the following program is run?

# print("Catch you later!")
print("Good-bye!")
print("Hope you are well.")
print("Hello!")

nothing, there is an error
There is no error in this program.
Catch you later!
Catch you later! is a comment, as indicated by the # sign, so it won’t be printed
Good-bye! Hope you are well. Hello!
Yes, the lines are printed in the order the Python interpreter gets to them, top to bottom.
Hello! Hope you are well. Good-bye!
While it might make sense to say hello before good-bye, the Python interpreter just follows instructions in order as given
Hello! Hope you are well. Good-bye! Catch you later!
No, that is not the order in which Python sees the instructions.
