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”.

==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertIn("Hello World", self.getOutput(), "Your output should contain a phrase Hello World") myTests().main()
