Question

use *python

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 PA, 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 three inputs, and then printing out the corresponding CPU performance category:

Press ENTER or type command to continue
Enter CPU gigahertz:
2.7
Enter CPU core count:
2
Enter CPU hyperthreading (True or False):
False

That is a low-performance CPU

• The first input, Gigahertz, should be converted to a float
• The second input, core count, should be an integer
• The third input, hyperthreading, should be a boolean. You should think of a way to go from a string 'True' or 'False' into a boolean True or False. (In case you were wondering, hyperthreading is a feature of some CPUs allowing for better performancce).

The program should spit out 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 print out should be based on the below tables:

If the CPU has hyperthreading

performance level	min GHz	min cores
high-performance	2.7	6
medium-performance	2.4	4
low-performance	1.9	2

If the CPU does not have hyperthreading

performance level	min GHz	min cores
high-performance	3.2	8
medium-performance	2.8	6
low-performance	2.4	2

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.

Examples

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

Enter CPU gigahertz:
2.0
Enter CPU core count:
8
Enter CPU hyperthreading (True or False):
True

That is a low-performance CPU.

Enter CPU gigahertz:
4.0
Enter CPU core count:
6
Enter CPU hyperthreading (True or False):
False

That is a medium-performance CPU.

'''

Python version : 2.7

Python program to determine the whether or not the specified CPU is within one of four categories:

high-performance, medium-performance, low-performance, and in need of an upgrade.

'''

# input of cpu gigahertz

cpu_ghz = float(raw_input('Enter CPU gigahertz:\n'))

cpu_hyperthreading_input = raw_input('Enter CPU hyperthreading (True or False):\n')

# convert the string input to boolean

if cpu_hyperthreading_input == 'True':

               cpu_hyperthreading = True

else:

               cpu_hyperthreading = False

              

# check if cpu cores >= 20, then high performance cpu      

if cpu_cores >=20:

               print('That is high-performance CPU.')

elif cpu_hyperthreading == True: # check if hyperthreading is True

              

               # cpu gigahertz is min 2.7 and cores are min 6, then high performance

               if(cpu_ghz >= 2.7 and cpu_cores >= 6):

               if(cpu_ghz >= 3.2 and cpu_cores >= 8):
