num = 0sum = 0while num <= 1000:? ? num = num + 1? ? if num % 2 > 0:? ? ? ? continue? ? sum = sum + num? ? ??print(sum)num作為計(jì)數(shù)器必須保證循環(huán)一次就加1。由于你把加1的語句放到了if條件后面，導(dǎo)致num是1的時(shí)候無法正常進(jìn)行加1，num永遠(yuǎn)是1,1永遠(yuǎn)小于1000.陷入了死循環(huán)。解決辦法：將num加1的語句放到循環(huán)開始的位置，保證每次循環(huán)num都可以加1

num是計(jì)數(shù)器，控制循環(huán)的次數(shù)。也可以用0,但是用1更直觀。比如控制循環(huán)次數(shù)為20。即為num<20。如果是0，控制循環(huán)次數(shù)為20，即為num<19。
