A. For loop is used for definite iterations while while loop is for indefinite iterations. B. For loop is faster than while loop. C. While loop can only be used with numbers while for loop can be used with any data type. D. There is no difference. ...
while loop can run indefinitely C. for loop is more complex D. none of the above 相关知识点: 试题来源: 解析 B。本题考查 for 循环和 while 循环的主要区别。while 循环可以根据条件无限运行,而 for 循环通常有明确的循环次数限制。选项 A 不准确,不能说 for 循环总是更快。选项 C 不准确,不一定...
1、For循环使用场景: (1)主要用来遍历/循环 序列、集合和字典 (2)循环使用 else 语句 在 python 中,for … else 表示这样的意思,for 中的语句和普通的没有区别,else 中的语句会在循环正常执行完(即 for 不是通过 break 跳出而中断的)的情况下执行,while … else 也是一样。 ** 2、while循环用法 ** ...
because you wrote : "while t<40" which does not include the 40, it self. But "for" contains the upper bound, which is 40. In other word, your first loop is done 4000 times, however, the "for" loop runs 4001 times. This may be the main result of difference that you are lookin...
Inside the while loop, the condition to be fulfilled is that the value of‘n’should always be greater than zero. Inside the loop, we add the value of‘n’to‘sum’and then decrement‘n’.While the value of‘n’will become zero, the while loop will stop executing and then print the...

Q #2) What is the difference between for loop and while loop? Answer:Afor loopis aniterator based loop, which steps through the items of iterable objects likelists,tuples, etc. While awhile loopis acondition-based loop, that executes a block of statements repeatedly as long as its condit...
We use FOR to iterate over a known range of values and WHILE to evaluate an expression. for (initialization; termination; increment) { statement(s) } while (expression) { statement(s) } The difference between WHILE and DO WHILE is that on WHILE it checks the condition first, than execute...
this has exactly the same results. The only difference is that you have an extra variableindex—but you may notice a similar variable (pointing straight at the item rather than at its element index number) in theforloop. Theindexvariable hangs around after thewhileloop where theitemvariable di...
Next, you'll move on to the for loop: once again, you'll learn how you can construct and use a for loop in a real-life context. You'll also learn the difference between using a while loop and a for loop. Also the topic of nested loops After, you'll see how you can use the ...
