左閉右開(kāi)[0:2]取第一個(gè)和第二個(gè)

反向索引最后一個(gè)下標(biāo)是-1

int取整

%取余

# coding=utf-8

print("是水仙花數(shù)")

else:

154除以100取余54,54除以10等于5.4取整為5

score = 30

if score >=60:

print("考試通過(guò)！")

print("名列前茅,重點(diǎn)表?yè)P(yáng)")

else:

print("繼續(xù)努力,潛力巨大")

else:

print("考試未通過(guò)，還需努力")

注意縮進(jìn)

整型（整數(shù)）不需要加雙引號(hào)，加了雙引號(hào)就是字符串

雙引號(hào)一定標(biāo)識(shí)字符串

# coding=utf-8

else :

print("我愛(ài)你")

由于是用記事本打開(kāi)編輯的所以對(duì)編碼有要求最終保存為utf-8 文件開(kāi)頭對(duì)應(yīng)utf-8? ?猜測(cè)是這個(gè)原因，也許我用個(gè)正經(jīng)編輯器就不會(huì)這樣

注意 （） not and or的優(yōu)先級(jí)
