# This code block is designed to repeatedly prompt the user for an integer input until a valid integer is entered.whileTrue:# This loop will continue indefinitely until a break statement is encountered.try:# The input() function is used to get user input, which is then passed to int() t...
Conclusion: Here, we have learned about how to make input only accept numbers in python, convert the input data into an integer, and handle errors using the try-except statement.
Output: Here, thewhileloop keeps on iterating until the user enters a valid number. Once the valid number is entered, thebreakstatement is executed toexitthe program. Using isdigit() method to check if the input is a number Theisdigit()methods returnsTrue, if all the characters in the str...
