Python While Loops are a very clever way to run or execute a block of code multiple times with different values. This allows you to write the logic in that block of code only once and provide a different value to be used each time you run the block of code.<\/p>\n\n\n\n

There are many ways to write loops in Python. One of them is by using a while<\/code> loop. The steps to create and use a while loop are:<\/p>\n\n\n\n

  1. Create a variable that holds the initial value.<\/li>
  2. Start a while loop with a condition that involves the variable created in step 1.<\/li>
  3. Write the logic inside the while loop that should be executed if the condition is True in step 2. The condition is always checked first and only if it\u2019s True, the logic inside of the while loop will be executed otherwise the code that follows the while loop will be executed.<\/li>
  4. Change the value of the variable created in step 1 inside the while loop.<\/li>
  5. Repeat.<\/li><\/ol>\n\n\n\n

    The generic syntax for a while loop is as follows (pay attention to indentation):<\/p>\n\n\n\n
