练习基本输入输出：
print('你好,{}.'.format(name))
print(sys.argv)
库的使用方法：
import ...
from ... import ...
条件语句：
if (abs(pos()))<1:
break
循环语句：
for i in range(5):
while True:
函数定义：
def mygoto(x,y):
def drawjx(r):
综合练习：画一面五星红旗，将代码与运行截图发布博客交作业。
import turtle def mygoto(x, y): turtle.up() turtle.goto(x, y) turtle.down() def drawF(x): turtle.begin_fill() for i in range (5): turtle.forward(x) turtle.right(144) turtle.end_fill() turtle.setup=(600, 400, 0, 0) turtle.color("yellow") turtle.bgcolor('red') turtle.fillcolor("yellow") mygoto(-270, 120) drawF(120) for i in range(4): x=1 if i in [0, 3]: x=0 mygoto(-120+x*30,150-i*40) turtle.left(15-i*15) drawF(30) mygoto(0, 0) turtle.hideturtle() turtle.done()
字符串练习：

取得校园新闻的编号
str = "http://news.gzcc.cn/html/2017/xiaoyuanxinwen_1027/8443.html" num = str.rstrip(".html").split("_")[1] print(num)
https://docs.python.org/3/library/turtle.html
产生python文档的网址
str1 = "https://docs.python.org/3.6/library/" str2 = ".html" str =str1+"turtle"+str2 print(str)
http://news.gzcc.cn/html/xiaoyuanxinwen/4.html
产生校园新闻的一系列新闻页网址
for i in range(2,10): str = "http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html".format(i) print(str)
练习字符串内建函数：strip,lstrip,rstrip,split,count，replace
用函数得到校园新闻编号
用函数统计一歌词(文章、小说)中单词出现的次数，替换标点符号为空格，用空格进行分词。
str = ''' I'm hurting, baby, I'm broken down I need your loving, loving, I need it now When I'm without you I'm something weak You got me begging Begging, I'm on my knees I don't wanna be needing your love I just wanna be deep in your love And it's killing me when you're away Ooh, baby, 'Cause I really don't care where you are I just wanna be there where you are And I gotta get one little taste Your sugar Yes, please Won't you come and put it down on me I'm right here, 'cause I need Little love and little sympathy Yeah you show me good loving Make it alright Need a little sweetness in my life Your sugar Yes, please Won't you come and put it down on me My broken pieces You pick them up Don't leave me hanging, hanging Come give me some When I'm without ya I'm so insecure You are the one thing The one thing, I'm living for I don't wanna be needing your love I just wanna be deep in your love And it's killing me when you're away Ooh, baby, 'Cause I really don't care where you are I just wanna be there where you are And I gotta get one little taste Your sugar Yes, please Won't you come and put it down on me I'm right here, 'cause I need Little love and little sympathy Yeah you show me good loving Make it alright Need a little sweetness in my life Your Sugar!
