In this tutorial, you'll learn about indefinite iteration using the Python while loop. You’ll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infinite loops.
One of the most common ways to detect EOF when reading from stdin is to use a while loop that reads input until there is no more data. Here is an example: while True: try: line = input() except EOFError: break # do something with line
The whileloop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1. The break Statement. With the breakstatement we can stop the loop even if the while condition is true: Example. Exit the loop when i is 3: i = 1. while i 6: print(i) if i == 3:
Learn how to use Python's while loop to execute a block of code repeatedly until a certain condition is met. This tutorial includes examples of while loop syntax, characteristics, and manipulation techniques such as the break and continue statements.
