Theelseblock with theforloop, is executed, once all the elements of the list are iterated or there are no more elements left to iterate in the list. It'll be safe to say thatelsestatement is executed at the end of the loop. Although, as already mentioned in the syntax, it's complete...
To end current iteration, and continues to next, use thecontinue keyword, it stops the current iteration of the Loop and transfers the program's control to the next one. Examples on Continue Statement Practice the following examples to learn the concept of ending the current iteration and contin...
In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, languages = ['Swift', 'Python', 'Go'] # start of the loop for lang in languages: print(lang) print('---') # end of the for loop print...
forxinrange(2,30,3): print(x) Try it Yourself » Else in For Loop Theelsekeyword in aforloop specifies a block of code to be executed when the loop is finished: Example Print all numbers from 0 to 5, and print a message when the loop has ended: ...
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...
people = ['Jack', 'Jim', 'John'] for (let i = 0; i < people.length; i++) { console.log("Here comes " + people[i]); } Copy Be careful about directly indexing successive elements in a list. If the loop is executed one too many times, you’ll end up with a runtime error...
译自 How (and When) to Use a Python While Loop，作者 Jack Wallen。While 循环是编程的一个基本要素。While 循环所做的是继续执行一条语句（或一组语句），直到满足特定条件。一个显而易见的例子（许多人都会理解）可能是这样的：只要我的银行账户有钱，我就可以买东西。该语句是我可以买东西，条件是只要...
Example 1:Print Numbers ranging from Start to End To achieve this, we will use thePython range function. This is how the flowchart will look like: Flowchart of for loop def range_from_start_to_end(start, end): for i in range(start, end+1): ...
