declare an integer in python

  x = 5

This code declares an integer variable, x, and assigns it a value of 5. The variable x can now be used throughout the program, and any time the program calls for x, the value 5 will be returned. Integer variables are useful for storing numbers and performing calculations that involve whole numbers. For example, if you wanted to calculate the total cost of five items, you could declare an integer variable called ‘total’ and give it an initial value of 0. Then, you could add the cost of each item to the total one at a time, giving the ‘total’ variable a new value each time. In the end, the ‘total’ variable would contain the sum of all the item costs.
