Can you use while loops with strings in Python?
However, if the string that the user inputs is not equal to the string password , the loop will continue. Inside of the while loop, the program runs a print statement that prompts for the password. Then the variable password is set to the user's input with the input() function. password = '' while password !=
What is while () in Python?
A while statement in python sets aside a block of code that is to be executed repeatedly until a condition is falsified. The structure of a while loop allows the total number of iterations, or repetitions, to be unknown from the start.
How do you use while in a string?
A while loop can be used with the String indexOf method to find certain characters in a string and process them, usually using the substring method. String s = "example"; int i = 0; // while there is an a in s while (s. indexOf("a") >= 0) // Find and save the next index for an a i = s.
How do you traverse a string in Python while loop?
Use the string index number to loop through the string
One way to iterate over a string is to use for i in range(len(str)): . In this loop, the variable i receives the index so that each character can be accessed using str[i] .
