Answer 1

Here is the code using the Python 3 programming language for the given question:

Afte code are the screenshots attached for the proper understanding of the indentation and output of the complied code is also attached.

Explanation of the code is provided using the comments in the code.

In this code, Custom exception has been created.

class Error(Exception):

"""Base class for other exceptions"""

pass

class ValueError(Error):

"""Raised when the input value is too small"""

pass

while True:

nums = list()

#list for storing values

for i in range(1,6):

#taking 5 inputs

number = input("Enter Number between 50 and 100: ")

#using exception handling to check number

try:

number = int(number)

if number > 50 and number < 101:

nums.append(number)

else:

#raising the exception

raise ValueError

except ValueError:

print("Number not in range")

continue

  

if len(nums)==5:

#slicing the list to get the values

a = nums[0]

b = nums[-1]

#printing sum and avgerage

print("Sum of 1st and 5th Numbers is ",a+b)

print("Average of 1st and 5th Number is ",((a+b)/2))

break
