Use the while Loop to Loop Over a String in Python The while loop is used just like the for loop for a given set of statements until a given condition is True. We provide the string’s length using the len() function for iterating over a string. In the while loop, the upper limit...
Python comes with two inbuilt keywords to interrupt loop iteration,breakandcontinue. Break Keyword In While loop The break keyword immediately terminates the while loop. Let's add a break statement to our existing code, x =1while(x<=3):print(x) x = x +1ifx ==3:breakelse:print("x is...
