这段代码首先初始化行数 row 为1，然后进入外层 while 循环。在每次外层循环中，列数 col 被重置为1，并进入内层 while 循环。内层循环打印当前行和列的乘法结果，并在每次迭代后递增列数 col。当内层循环完成后，打印一个换行符，然后递增行数 row 并继续外层循环。这个过程一直持续到行数达到10。运行这段代码...

In Python, “for-loop” is widely used to iterate over a sequence, list, or any object. For loop avoids multiple usages of code lines to make the program concise and simple. The “One line for loop” is also the form of “for loop” which means that a complete syntax of “for loop...
While Loop The while loop is one of the first loops that you'll probably encounter when you're starting to learn how to program. It is arguably also one of the most intuitive ones to understand: if you think of the name of this loop, you will quickly understand that the word "while"...
Since we are not using the items of the sequence(0, 1, 2 and 4) in the loop body, it is better to use _ as the loop variable. Also read: Python while loopBefore we wrap up, let’s put your knowledge of Python for loop to the test! Can you solve the following challenge?

while 语句 在Python 中,while 语句用于循环执行一段程序,它和 if 语句一样,两者都离不开判断语句和缩进。 每当写在 while 语句下的程序被执行一次,程序就会自动回到“顶上”(也就是 while 语句的开头部分),根据 while 后的判断语句的返回值来决定是否要再次执行该程序,如果判断语句的返回值为 True,则继续执行...
