c = result[0] 的意思是result中的第一個值。前面調用函數(shù)得出長方形的周長和面積，把64，256存到result中，現(xiàn)在把這個第一個值，也就是64存到變量c里，再打印出來。如果還不懂就回去看看前面關于列表索引那一塊吧

這個是根據(jù)需要來設置的，第一段代碼if 與 print之間與print之后的num+=1均是因為要將num的量增加1以便于后續(xù)運算；只是如果num<10，continue后面的代碼無法運行，但是為了整體依然需要num+=1，故在continue之前再次放了num+=1，其實不是放在print前后的問題，而是放在continue前后的問題。要理解continue跳出循環(huán)的用法。第二個最后print輸出的是while-if嵌套語句循環(huán)執(zhí)行后的sum，所以放在最后，而num+=1的放法也是根據(jù)contin...
