Answer:
#program in Python
#read until user Enter an integer
while True:
#try block to check integer
try:
#read input from user
inp = int(input("Enter an integer: "))
#print input
print("The integer is: ",inp)
break
#if input is not integer
except ValueError:
#print message
print("Wrong: try again.")
Explanation:
In try block, read input from user.If the input is not integer the print a message in except block.Read the input until user enter an integer. When user enter an integer then print the integer and break the loop.
Output:
Enter an integer: acs
Wrong: try again.
Enter an integer: 4a
Wrong: try again.
Enter an integer: 2.2
Wrong: try again.
Enter an integer: 12
The integer is: 12
