Here is the basic syntax of a while<\/code> loop:<\/p>\nwhile condition:\r\n # code to be executed\r\n<\/pre>\n
True<\/code>, the code inside the loop is executed. Afterward, the condition is checked again, and the loop continues until the condition becomes False<\/code>.<\/p>\nwhile<\/code> loop that prints the numbers from 1 to 5:<\/p>\ncount = 1\r\nwhile count <= 5:\r\n print(count)\r\n count += 1\r\n<\/pre>\n
count<\/code> variable is initialized to 1. The condition count <= 5<\/code> is checked at the beginning of each iteration. If it is True<\/code>, the current value of count<\/code> is printed to the console and count<\/code> is incremented by 1. After 5 iterations, the value of count<\/code> is 6, which is not less than or equal to 5, so the loop ends.<\/p>\nbreak<\/code> statement inside a while<\/code> loop to terminate the loop prematurely. For example, the following code uses a while<\/code> loop to repeatedly ask the user for input until they enter a non-empty string or type “quit”:<\/p>\nwhile True:\r\n user_input = input(\"Enter something (or type 'quit' to exit): \")\r\n if user_input == \"\":\r\n print(\"You didn't enter anything!\")\r\n elif user_input == \"quit\":\r\n break\r\n else:\r\n print(\"You entered:\", user_input)\r\n<\/pre>\n
while<\/code> loop runs indefinitely (True<\/code> is always True<\/code>). However, the break<\/code> statement is used to exit the loop when the user types “quit”.<\/p>\ncontinue<\/code> statement to skip the rest of the current iteration and move on to the next one. For example, the following code uses a while<\/code> loop to print the numbers from 1 to 10, skipping the even numbers:<\/p>\ncount = 1\r\nwhile count <= 10:\r\n if count % 2 == 0:\r\n count += 1\r\n continue\r\n print(count)\r\n count += 1\r\n<\/pre>\n
if<\/code> statement checks if the current value of count<\/code> is even. If it is, the continue<\/code> statement is executed, which skips the rest of the current iteration (including the print<\/code> statement) and moves on to the next iteration.<\/p>\n\n
else<\/code> clause to specify a block of code that should be executed when the loop terminates normally (i.e., when the condition becomes False<\/code>). For example, the following code uses a while<\/code> loop to find the smallest power of 2 that is greater than or equal to a given number:<\/li>\n<\/ul>\nnum = 20\r\npower = 1\r\nwhile power < num:\r\n power *= 2\r\nelse:\r\n print(\"The smallest power of 2 that is greater than or equal to\", num, \"is\", power)\r\n<\/pre>\n
while<\/code> loop multiplies power<\/code> by 2 on each iteration until it is greater than or equal to num<\/code>. When the loop terminates (because the condition power < num<\/code> is no longer True<\/code>), the else<\/code> block is executed, which prints a message to the console.<\/p>\n\n
while-else<\/code> construct to combine the while<\/code> loop and else<\/code> clause into a single statement. The else<\/code> block is executed when the condition becomes False<\/code>, just like in the previous example. However, if you use the break<\/code> statement to exit the loop prematurely, the else<\/code> block will not be executed. For example, the following code uses a while-else<\/code> loop to print the numbers from 1 to 5:<\/li>\n<\/ul>\ncount = 1\r\nwhile count <= 5:\r\n print(count)\r\n count += 1\r\nelse:\r\n print(\"Finished!\")\r\n<\/pre>\n
while<\/code> loop prints the numbers from 1 to 5 and then terminates normally (because the condition count <= 5<\/code> is no longer True<\/code>). The else<\/code> block is then executed, which prints a message to the console.<\/p>\n<\/h3>\n
