例2、还是上面的程序,但是遇到小于5的循环次数就不走了,直接跳入下一次循环: for i in range (10): if i < 5: continue print("loop:",i) # 输出 loop: 5 loop: 6 loop: 7 loop: 8 loop: 9 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Python continue语句跳出本次循环 continue 语句用来...
2、range()函数的通常用法: 通常记数方式,从0开始,我们计算机进行运算时,通常以0为起点。 for i in range(0, 5): print("hello") 1. 2. 3、range()简写 for i in range(5): print("hello") 1. 2. 三、跳出循环 break for name in ["李老师", "王老师", "李老师"]: print(name, "说:...
for(int i=1; i<501; i++)Python 把这个循环进行简化了。我们可以使用下面的代码来在 Python 中执行循环:for i in range(1, 501):直接使用一个 range 函数。start: 计数从 start 开始。默认是从 0 开始。例如range(5)等价于range(0, 5);stop: 计数到 stop 结束,但不包括 stop。例如:range(...

In Python, the for loop is used to iterate over a sequence such as a list, string, tuple, other iterable objects such as range. With the help of for loop, we can iterate over each item present in the sequence and executes the same set of operations for each item. Using a for loo...

Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function works really well. When working withrange(), you can pass between 1 and 3 integer arguments to...
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 print(sum) ...
