while loop in python programming
- A Python ‘while loop’ repeatedly carries out a target statement while the condition is true.
- The loop iterates as long as the defined condition is true. When it ceases to be true and becomes false, control passes to the first line after the loop.
- Python while statement is the most general iteration construct in the language.
- Its called a loop because control keeps looping back to the start of the statement until the test becomes false.
Syntax
