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 turtledef 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)

 

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"+str2print(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。
