In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows code to be executed repeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed once per iteration. (...
1. C Program to Print the 1 to 10 Multiples of a Number #include<stdio.h> int main() { int n; printf("Enter a number: "); scanf("%d", &n); for(int i =1; i<=10;i++) { printf("\n%d*%d = %d ",n,i,n*i); } return 0; } Copy Output: Enter a number: 5...
在这个示例中,我们首先创建了一个包含1到10的数字列表numbers,然后使用for循环遍历该列表,并将每个数字的平方添加到新的列表squared_numbers中。最后,我们打印出squared_numbers的结果,即每个数字的平方。 流程图 下面是一个表示上述操作流程的流程图: StartCreateListForLoopAddToNewListEnd 以上流程图展示了整个操作的...
for i in range(3): if i == 2: break print(i, end=' ') # 打印0和1 else: print("Loop completed without encountering a 'break' statement.")5.循环控制语句:range()函数:生成一个起始默认为0的序列,通常与for循环一起使用。def print_numbers(n): for i in range(1, n+1): print(i)...
1 print("Hello World!") 1. 然后再执行 python hello.py,就可输出 1 localhost:~ jieli$ vim hello.py 2 localhost:~ jieli$ python hello.py 3 Hello World! 1. 2. 3. 上一步中执行 python hello.py 时,明确的指出 hello.py 脚本由 python 解释器来执行。

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...
1. For loop的执行顺序 参考:https://kelepython.readthedocs.io/zh/latest/c01/c01_10.html#for For loop是一个遍历命令,意味着要把一个序列里的所有元素都循环一遍。 Python执行for loop从第一行到最后一行,exp: for question in questions: print("---") print(question) for option in options[question...
