try:
    num1 = int(input ("Enter the first number"))
    num2 = int(input("Enter the second number"))
    quotient=(num1/num2)
    print ("Both the numbers entered were correct")
except ________:           # to enter only integers
    print (" Please enter only numbers")
except __________:       # Denominator should not be zero
    print(" Number 2 should not be zero")
else:
    print(" Great .. you are a good programmer")
___________________ :       # to be executed at the end

Answer 1

The try statement in Python can also have an optional finally clause. The statements inside the finally block are always executed regardless of whether an exception has occurred in the try block or not. It is a common practice to use finally clause while working with files to ensure that the file object is closed. If used, finally should always be placed at the end of try clause, after all except blocks and the else block.

print (" Learning Exceptions…")
try:
    num1= int(input (" Enter the first number")
    num2= int(input("Enter the second number"))
    quotient=(num1/num2)
    print ("Both the numbers entered were correct")
except ValueError: # to enter only integers
    print (" Please enter only numbers")
except ZeroDivisionError: # Denominator should not be zero
    print(" Number 2 should not be zero")
else:
    print(" Great .. you are a good programmer")
finally : # to be executed at the end
print(" JOB OVER… GO GET SOME REST")
