左閉右開[0:2]取第一個和第二個

反向索引最后一個下標是-1

print(books[0:4])

print(books[0:-1])

# coding=utf-8

books = ["紅樓夢","三國演義","水滸傳","西游記","聊齋志異"]

int取整

%取余

# coding=utf-8

n=154

a=int(n/100)

b=int(n%100/10)

c=n%10

print(a)

print(b)

print(c)

re=a*a*a+b*b*b+c*c*c

if n==re:

print(n,end="")

print("是水仙花數")

else:

print(n,end="")

print("不是水仙花數")

154除以100取余54,54除以10等于5.4取整為5

# coding=utf-8

score = 30

if score >=60:

print("考試通過！")

if score >= 90:

print("名列前茅,重點表揚")

else:

print("繼續努力,潛力巨大")

else:

print("考試未通過，還需努力")

注意縮進

整型（整數）不需要加雙引號，加了雙引號就是字符串

雙引號一定標識字符串

# coding=utf-8

la = "德語"

if la == "德語" :

print("Ich liebe dich")

elif la == "韓語" :

print("???")

elif la == "英語" :

print("I love you")

else :

print("我愛你")

由于是用記事本打開編輯的所以對編碼有要求最終保存為utf-8 文件開頭對應utf-8? ?猜測是這個原因，也許我用個正經編輯器就不會這樣

注意 （） not and or的優先級

# coding=gbk

r1 = 1 != 1 or 8 < 2 and 6? > 3

print(r1)

r2 = 1 != 1 or not 8 < 1 and 6 > 3

print(r2)

r3 = 1 != 1 or not (8 < 1 and 6 > 3)

print(r3)

x = 700

re = (1000 - x) * 30

print(re)

if(re >= 1 and re <= 10000) :

print("結果落在區間內")

else :

print("結果未落在區間內")

# coding=gbk

x=1600

re = (1000-x)*30

print(re)

if re >10000 :

print("結果大于10000")

else :

print("結果小于10000")

True False? 首字母是大寫的

# coding=gbk

if 8 > 6 :

print("判斷條件成立")

else :

print("判斷條件不成立")

yntaxError: Non-ASCII character '\xe5' in file index.py on line 7, but no encoding declared; see http://python.org/dev/p

開頭加# -*- coding: UTF-8 -*-

不好使就加#coding=gbk? 總有一款適合你
