**Python program to specify Number of integers and Compute the Largest**

Below is the Python program that given a list of integers, computes the MAXIMUM/LARGEST number. The program expects a positive Integer as the Input to the “*Number of integers to enter*“, and exits gracefully with a custom message “*The value you entered is a non-Integer OR -ve Integer!*” otherwise. The program also checks if the numbers entered are positive/negative Integers and rejects any other type, requesting the user for a positive/negative Integer instead!

```
#!/usr/bin/python3
numberCount = 0
total =0
average = 0
integerList = []
n = 0
greatestNumber = 0
index = 0
upperLimit = input("How many integers do you want to enter to find the one with the Maximum value?: ")
if upperLimit.isdigit() == True:
upperLimit = int(upperLimit)
print("Please enter {} integers to find the Maximum value! \n\n".format(upperLimit))
while numberCount < upperLimit:
number = input("Enter number:")
try:
number = float(number)
if number.is_integer():
integerList.append(number)
numberCount += 1
if numberCount == 1:
greatestNumber = number
else:
if greatestNumber > integerList[-1]:
greatestNumber = greatestNumber
else:
greatestNumber = integerList[-1]
if greatestNumber in integerList:
index = integerList.index(greatestNumber)
except:
print("You entered a non-Integer, instead enter a +ve/-ve Integer!")
print("\n\nYou entered {} integers. The Largest number is: ".format(upperLimit) + str(int(greatestNumber)) + ", and its index is " + str(index) + "!")
else:
print("The value you entered is a non-Integer OR -ve Integer!")
```
