Below is a completion of the Python program that computes the largest and smallest of three integer values (-50, 53, 78):
The Completed Code
# LargeSmall.py - This program calculates the largest and smallest of three integer values.
# Declare and initialize variables here
firstNumber = -50
secondNumber = 53
thirdNumber = 78
# Write assignment, if, or if else statements here as appropriate
largest = max(firstNumber, secondNumber, thirdNumber)
smallest = min(firstNumber, secondNumber, thirdNumber)
# Output largest and smallest number.
print("The largest value is " + str(largest))
print("The smallest value is " + str(smallest))
This completion utilizes Python's max() and min() functions to find the largest and smallest values among the given integers and prints the results accordingly. The output will display:
The largest value is 78
The smallest value is -50
