Question

Write a program that reads two numbers from the user, and proceeds as follows: If the input numbers are equal, the program displays: both numbers are the same. Otherwise, the program logs all the integers in the range of the input numbers from the smaller value to the larger value in the console. For example, if the user enters 22 and 16, the program displays: 16 17 18 19 20 21 22. Note that all the numbers are displayed in one line separated by a single space. . If any of the input values are invalid, the program displays an error message and terminates.​

Answer 1

import sys

x = input("enter number 1: ") #ask for user input

y = input("enter number 2: ")

output = "" #the output string

try: #try integering them (this also has error message and will check if input is valid)

 x = int(x)

except:

 print("error! number 1 was not a number :(")

 sys.exit() #leave

try:

 y = int(y)

except:

 print("error! number 2 was not a number :(")

 sys.exit()

if x == y: #check they are not the same

 print("both numbers are the same")

else: #do the thing

 if y > x: #otherwise swap the order

   for i in range (x, y + 1): #+1 for inclusive

     output = (output + str(i) + " ")

 else:

   for i in range (y, x + 1):

     output = (output + str(i) + " ")

 print(output) #so it's all in one line
