for i in list(range(5)): print(i) 系统输出: 0 1 2 3 4 这是一个最简单的for循环。list(range(5))代表的实体为[0,1,2,3,4]. 上述循环的含义就是生成一个变量i,并让i指代list[0,1,2,3,4]中的每一个数字,并进行输出。 例2: 输入: sum=0 for x in list(range(10)): sum=sum+x ...
When we have a for loop inside another for loop, it’s called a nested for loop. There are multiple applications of a nested for loop. Consider the list example above. The for loop prints out individual words from the list. But what if we want to print out the individual characters of...

for Loop with Python range() In Python, the range() function returns a sequence of numbers. For example, # generate numbers from 0 to 3 values = range(0, 4) Here, range(0, 4) returns a sequence of 0, 1, 2 ,and 3. Since the range() function returns a sequence of numbers, we...
for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to be...
Set sumvariableto zero. Use therange(2, 22, 2)to get all even numbers from 2 to 20. (Here astepvalue is 2 to get the even number because even numbers are divisible by 2) Next, useforloop to iterate over each number In each iteration add the current number to the sum variable usi...
使用缩进将for循环的主体与其余代码分开。 for循环流程图Python中for循环的流程图 示例:Python for循环 示例 #程序查找列表中存储的所有数字的总和 #数字清单 numbers = [6, 5, 3, 8, 4, 2, 5, 4, 11] # 用于存储总和的变量 sum = 0 # 遍历列表 for val in numbers: sum = sum+val print("总和...
for fruit in fruits:print(fruit)这将打印：apple banana cherry 在for循环中，我们还可以使用else语句来执行一些代码，当循环正常结束时，而不是因为break语句或异常而结束时。例如：python for num in range(5):print(num)else:print('Loop has ended normally')这将打印：yaml 0 1 2 3 4 Loop has ended...
