A python program to accept an integer number from keyboard version 2.||
This program uses a while loop to repeatedly prompt the user to enter an integer number until a valid input is provided. Inside the loop, the program first gets the user input as a string using the input() function, and then checks if the string consists only of digits using the isdigit() method. If it does, the program converts the string to an integer using the int() function and exits the loop using the break statement. If the string contains non-digit characters, the program prints an error message and continues the loop.
Finally, the program prints the value of number using the print() function.
This program provides a more concise way of checking if the user input is a valid integer by using the isdigit() method, which returns True if all characters in the string are digits.
