ASSIGNMENT

You are going to enhance the prior assignment by doing the following:

• Create a function for each math operation (add, div, mult, sub).
• The application will run forever (while True), you will ask the user to continue or not.
• Create a function IsInRange() to test a number between two numbers like this.

Here is the spec in pseudo-code

IsInRange(lr, hr, n)

lr=low range

hr=high range

n=number

if n between ln and hr

    return true

else

    return false

>>> Show me how to use the function isInRange()

for example, we can check if the inputs are between -10 and 10 then do the calculations. else print "values are not in range" and loop back. use input() to get the ranges.

SAMPLE OUTPUT:

Enter your First number —> 15
Enter your Second number —> 17

The result of 15.0+17.0=32.0
The result of 15.0-17.0=-2.0
The result of 15.0*17.0=255.0
The result of 15.0/17.0=0.882352941176

Continue Looping Y/N Y

Sample output using ranges.

Enter your Lower range —> 10
Enter your Higher range —> 50
Enter your First number (10 – 50) —> 5     <<<  10 and 50 from input, do not hard code.

Enter your Second number (10 – 50) —> 60

The input values are outside the input ranges
Please check the numbers and try again.

HINTS:

1) program structure

while True:

         ask the user do want more calculations (y/n)

         if yes then

FUNCTIONS:

A function is a set of code that only runs when it is called. You can pass data, known as parameters, into a function. A function can return value as a result. Python can return more than one value.

# When creating a function, you must pass a parameter(s) and return at least one value.

Do not use global variables.

def add(fnum, snum):
    return fnum+snum

# in the program using the add()
res=add(6,8)
print(res) 
print("The result =", res)

# function returning more than one value

def epay(employee, rate, hours):

      pay=rate*hours

      return employee, rate, hours, pay

#using epay

print( epay("Bnudy", 3.50, 32)) # ('Bnudy', 3.5, 32, 112.0)

# or

name, hrate, hrs, pay=epay("Bnudy", 3.50, 32)

print(name, hrate, hrs, pay)

# or

print(f"Name={name}, rate={hrate}, hours={hrs} and the pay={pay}")

# here is the output
('Bnudy', 3.5, 32, 112.0)

Bnudy 3.5 32 112.0

Name=Bnudy, rate=3.5, hours=32 and the pay=112.0

>>> How do I do something like this

Enter your First number (10 – 50) —> 5     <<<  10 and 50 from input, do

try this

n1=50

n2=100

input(f'Enter your First number ('{n1} – {n2})')

# Test a number between two numbers
# checknum()
def checknum(lb,num,ub):

    #lb = lower bound

    #ub = upper bound

    #num = number to be tested if it is between lb and ub

    #returns true if the number between lb and ub   

    return lb < n < ub
 

#test checknum()
print( checknum(10,5,20)) 
print( checknum(10,11,20))
