python 在一個(gè)范圍內(nèi),尋找另一個(gè)數(shù)字的所有整數(shù)倍數(shù),并計(jì)算一共有多少個(gè)倍數(shù)
這個(gè)是問題,真心不會(huì)做.我用的是python 2.7.要用 for loop
1) 建立程序 count_multiples() which takes 三個(gè)非負(fù)整數(shù):base,start and stop,prints each integer multiple of base which
occurs between start and stop (including start but not including stop) on a separate line,
and returns the number of multiples found.假如 base = 3,那在start = 9 和stop = 15之間就有2個(gè)整倍數(shù),9 和 12,但不包括15.the easiest way to test whether one number is an integer multiple of another is with the % operator.
\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05
\x05\x05\x05\x05
\x05\x05\x05
\x05\x05
\x05\x05\x05
\x05\x05\x05\x05
\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05
2）.Write a function user_input_multiples() which takes a single integer input base.This
function will get start and stop values from the user with two calls to raw_input(),call
count_multiples() to determine the number of integer multiples of base between the user
specified start and stop,and then ask again for new start and stop values.The function will
continue asking for new start and stop values until at least one of the following cases occurs:
\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05\x05
 The user enters a negative value for start or stop.
\x05\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05\x05
 The user enters a value for stop which is less than the value for start.
\x05\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05
\x05\x05\x05\x05\x05\x05\x05\x05\x05
 The function count_multiples() returns zero (eg:there were no multiples between start and stop).
Once the function stops asking for input,it will return the total number of multiples found (the total
over all calls to count_multiples()).Hint:You will
want to use a while loop for this function.
英語有點(diǎn)多,看著有點(diǎn)煩,請(qǐng)見諒.第一部分我已經(jīng)盡量翻譯最主要的舉例了.
如果沒有時(shí)間,給我一個(gè)詳細(xì)的思路或者方向也行.:)
