CPU Category

Though CPUs, and computer hardware in$-$general, are not the main focus of this course, it can be useful

to know a thing or two about computer hardware. The CPU $($Central Processing Unit$)$ is generally the

piece of hardware that carries out the instructions of the python programs that you run in this class.

In this short project, you will write a program that takes a few input values related to CPU performance.

The program should determine whether or not the specified CPU is within one of four categories: high$-$

performance, medium$-$performance, low$-$performance, and in need of an upgrade. Name the file

cpu.py$.$

Shown below is an example of the program prompting the user for two inputs, and then printing out the

corresponding CPU performance category:

def main$()$:

gigahertz $=2\mathrm{.}7$

core$\_$count $=2$

result $=$ get$\_$result$($gigahertz$,$ core$\_$count$)$

print$($result$)$

main$()$

That is a low$-$performance CPU.

The first argument, Gigahertz, should be converted to a float

The second argument, core count, should be an integer

The program should return one of $4$ strings:

That is a high$-$performance CPU.

That is a medium$-$performance CPU.

That is a low$-$performance CPU.

That CPU could use an upgrade.

How you determine which to return should be based on the below table:

For example, a medium$-$performance CPU must satisfy both requirements: a$)$ GHz no less than $2\mathrm{.}5$ and

b$)$ cores no less than $6.$

There's also one "special$-$case" rule: If a CPU has $20$ or more cores, regardless of the other stats, it

should be considered high$-$performance.

Test Cases

Below are examples of program runs. There will be more tests on Gradescope.

def main$()$:

gigahertz $=2\mathrm{.}0$

core$\_$count $=8$

assert get$\_$result$($gigahertz$,$ core$\_$count$)==$ "That is a low$-$performance CPU."

gigahertz $=4\mathrm{.}0$

core$\_$count $=7$

assert get$\_$result$($gigahertz$,$ core$\_$count$)==$ "That is a medium$-$performance CPU."

gigahertz $=1\mathrm{.}0$

core$\_$count $=10$

assert get$\_$result$($gigahertz$,$ core$\_$count$)==$ "That CPU could use an upgrade."

print$("$End of tests"$)$
