The loop is a sequence of instructions that gets executed repeatedly until and unless an exit condition is reached. There are two types of loops in Python: For Loop: This Loop iterates over a sequence like lists, strings, tuples or any other iterable object and is used when the number of...

Let’s take a closer look at common ways aforloop can causeList Index Out of Rangeand how to either avoid it completely or gracefully handle this error when it crops up. What causes the “List Index Out of Range” error? As Python uses zero-based indexing, when you try to access an...
In practice, most Python objects and expressions aren’t Boolean. In other words, most objects and expressions don’t have a True or False value but a different type of value. However, you can use any Python object in a Boolean context, such as a conditional statement or a while loop....
To avoid these problems, there's some rules to follow:为了避免while循环一直执行,请遵循以下规则:1. Make sure that you use while-loops sparingly. Usually a for-loop is better.尽量节制使用while循环,通常使用for循环会更好些。2. Review your while statements and make sure that the thing you are...
