Question

Suppose num, lowVal, and highVal are variables with existing numeric values, and lowVal <= highVal. Write an expression that is True if num is in the interval from lowVal to highVal, allowing the endpoint values lowVal and highVal. For instance, if lowVal is 2 and highVal is 5, your expression should be True if num is 2, 3, 4.4 or 5, but false if num is -1, 1.9, 5.1, 7 or 100000.

Answer 1

ANSWER:

• The required expression is:

(num >= lowVal) and (num < = highVal)

here, and operator is used to satisfy both the conditions

• Testing the expression in Python, I have provided code in both text and image format so it will be easy for you to copy the code as well as check for correct indentation.
• Output of the code is attached to cross check for correct result of the code.

CODE TEXT

# Python 3
# defining variables.
lowVal = 2
highVal = 5
nums=[2,3,4.4,5,-1,1.9,5.1,7,100000]
# using loop to iterate through each value of num
for num in nums:
exp = (num>=lowVal) and (num<=highVal)
print('Output for ',num,' is: ',exp)
