(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 + ...

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
Just to get a bit more practice on for loops, see the following examples: numbers = [1,10,20,30,40,50] sum = 0 for number in numbers: sum = sum + number print sum Loop through words Here we use the for loop to loop through the word computer ...
Print all items by referring to their index number: thistuple = ("apple", "banana", "cherry") for i in range(len(thistuple)): print(thistuple[i]) Try it Yourself » Using a While LoopYou can loop through the tuple items by using a while loop.Use...
In Python, for loops are compound statements with a header and a code block that runs a predefined number of times. The basic syntax of a for loop is shown below: Python Syntax for variable in iterable: In this syntax, variable is the loop variable. In each iteration, this variable...
Just as with while loops, the continue statement can also be used in Python for loops to terminate the ongoing iteration and transfer the control to the beginning of the loop to continue the next iteration. Python 1 2 3 4 5 6 7 number_list = [2,3,4,5,6,7,8] for i in number...
