(Here a step value is 2 to get the even number because even numbers are divisible by 2) Next, use for loop to iterate over each number In each iteration add the current number to the sum variable using the arithmetic operator. sum = 0 for i in range(2, 22, 2): sum = sum + ...
Swift in the first iteration. Python in the second iteration. Go in the third iteration. for loop Syntax for val in sequence: # run this code The for loop iterates over the elements of sequence in order, and in each iteration, the body of the loop is executed. The loop ends after th...

Loop Through the Index NumbersYou can also loop through the list items by referring to their index number.Use the range() and len() functions to create a suitable iterable.Example Print all items by referring to their index number: thislist = ["apple", "banana", "cherry"]for i in ...
Exit the loop whenxis "banana", but this time the break comes before the print: fruits = ["apple","banana","cherry"] forxinfruits: ifx =="banana": break print(x) Try it Yourself » The continue Statement With thecontinuestatement we can stop the current iteration of the loop, and...
We can userange()function along with theforloop to iterate index number from0tolen(myList). It will be pretty much like: 我们可以将range()函数与for循环一起使用,for将索引号从0迭代到len(myList)。 它将非常像: for i in range(0, len(myList)): ...
Python for Loops: The Pythonic Way In this quiz, you'll test your understanding of Python's for loop. You'll revisit how to iterate over items in a data collection, how to use range() for a predefined number of iterations, and how to use enumerate() for index-based iteration.Getting...
此外,我们还可以利用Mermaid语法中的sequenceDiagram来展示for循环的执行过程: OperationElementIterationFor LoopUserOperationElementIterationFor LoopUserStartIterateGet elementPerform operationContinueEnd 6. 结尾 通过这篇文章,我们详细介绍了如何在Python中实现“for循环结束后”的操作。从初始化变量到编写for循环,再到在...
Python序列 在Python中,序列类型包括字符串、列表、元组、集合和字典,这些序列支持以下几种通用的操作,但比较特殊的是,集合和字典不支持索引、切片、相加和相乘操作。 字符串也是一种常见的序列,它也可以直接通过索引访问字符串内的字符。 序列索引 序列中,每个元素都
You can tackle the for loop in the same way as the while loop. As you probably would have expected, the "for" component in "for loop" refers to something that you do for a certain number of times. If you keep all the above in mind, you can easily define the for loop as follows...
