The for loops and range for loops that you learned in Chapter 3 are convenient for looping through a string or range of indices. But what do we do when we have no string or when the indices do not follow a fixed pattern? We use a while loop, the topic of this chapter. while loops are more general than for loops and can handle situations that a for loop cannot.
We’ll solve three problems where for loops fall short: determining the number of times slot machines can be played, organizing a song playlist until the user wants to stop, and decoding an encoded message.
