Python Program to Check if a Number is Positive, Negative or 0 Before we wrap up, let's put your understanding of this example to the test! Can you solve the following challenge? Challenge: Write a function to check if the entered integer is odd or even. If the given number is odd...
Use stringisdigit()method to check user input is number or string Note: Theisdigit()function will work only for positive integer numbers. i.e., if you pass any float number, it will not work. So, It is better to use the first approach. Let’s execute the program to validate this. d...
