target heartrate zone when exercising is:

$20$ years old is $100$ to $170$ beats per minute

$30$ years old is $95$ to $162$ beats per minute

$35$ years old is $93$ to $157$ beats per minute

$40$ years old is $90$ to $153$ beats per minute

$45$ years old is $88$ to $149$ beats per minute

$50$ years old is $85$ to $145$ beats per minute

$55$ years old is $83$ to $140$ beats per minute

$60$ years old is $80$ to $136$ beats per minute

$65$ years old is $78$ to $132$ beats per minute

$70$ years old is $75$ to $128$ beats per minute

We will use the age as a minimum. So the first block will be $20$ to $29$ years old.

Use heart.py$.$ It included main$()$ and imports the Person class.

main$()$ will prompt the user for a name and an age

Set those values

Print the information about the person and the target heart rate

You must write the Person class in person.py

You must use heart.py that is provided in the Test zip file

The Person class should have:

A constructor that can have name and age passed in$.$ The name should default to $$ and the age should default to $21$

A $\_\_$str$\_\_$ function that formats as the name, a space, $(,$ the age, a space, $$years old$)$

Make getter$/$setter properties as needed

Because of the way we have the age ranges, we will not allow any person to be younger than $20$ years old. Raise a ValueError, with the message $$invalid age$,$ if there is an attempt to set the age to less than $20.$ Then let main$()$ print that message

A get$\_$target$\_$rate function that has no parameters and returns a tuple with the min and max target heart rate

Sample Run #$1($bold$,$ underlined text is what the user types$)$:

Name? Sue

Age? $25$

Sue $(25$ years old$)$

Sue should aim for $100$ to $170$ bpm

Test #$1$ checks all output

Mini Test #$2$ output includes $$Sue $(25$ years old$)$ and $$Sue should aim for $100$ to $170$ bpm$$ on consecutive lines

Note: This is an introductory level python class and programming should reflect this. This problem covers classes and is composed of two different python scripts: heart.py $($already written and is just called upon in person.py$)$ and person.py $($this is what is actually being coded$).$ There is a sample test of what the output should look like when the program is runned.
