1：用循环画五角星
1 import turtle2 3 turtle.fillcolor("red")4 turtle.begin_fill()5 for i in range(5):6 turtle.forward(100)7 turtle.right(144)8 turtle.end_fill() 2：用循环画同心圆
1 import turtle2 for i in range(3):3 turtle.up()4 turtle.goto(0,-50*(i+1))5 turtle.down()6 turtle.circle(50*(i+1))
3：用while循环画太阳花
1 import turtle2 turtle.color('red','yellow')3 turtle.begin_fill()4 while True:5 turtle.forward(200)6 turtle.left(170)7 if abs(turtle.pos()) < 1:8 break9 turtle.end_fill() 4：用函数定义画五个五角星

字符串操作
1：输入学号，识别年级、专业、序号。
1 majors = { 2 11:'网络工程', 3 12:'软件工程', 4 13:'数字媒体', 5 } 6 7 def recognition(studentID): 8 if len(studentID)<12: 9 print("请输入正确的学号！")10 elif studentID.isdigit() != True:11 print("请输入正确的学号！")12 else:13 grade = studentID[0:4]14 major = studentID[6:8]15 num = studentID[10:12]16 print("年级：{}级".format(grade)) 17 print("专业为：",majors.get(int(major)))18 print("序号:{}".format(num))19 20 studentID = input("请输入学号：")21 recognition(studentID) 2：输入1-7的数字，输出对应的“星期几”。
1 s="星期一星期二星期三星期四星期五星期六星期天"2 i=int(input("请输入(1-7)："))3 if(0<8):4 print(s[-3+3*i:0+3*i])5 else:6 print("输入有误!") 3：识别身份证号中的省市区、年龄、性别。
1 ID=input('请输入十八位身份证号码: ') 2 if len(ID)!=18: 3 print("错误的身份证号码!!") 4 5 ID_add=ID[0:6] 6 ID_birth=ID[6:10] 7 ID_sex=ID[14:17] 8 9 if int(ID_add)==440101:10 print("省市区:广东省广州市市辖区")11 elif int(ID_add)==440102:12 print("省市区:广东省广州市东山区")13 elif int(ID_add)==440103:14 print("省市区:广东省广州市荔湾区")15 elif int(ID_add)==440104:16 print("省市区:广东省广州市越秀区")17 elif int(ID_add)==440105:18 print("省市区:广东省广州市海珠区")19 20 21 birth=2017-int(ID_birth[0:4])22 print("年龄：{}".format(birth))23 24 if int(ID_sex)%2==0:25 print('性别：女')26 else:27 print('性别：男') 4：用字符串操作生成python文档各库的网址(起始网址在这里)
1 yyx1 = "https://docs.python.org/3.6/library/"2 yyx2 = ".html"3 yyx3 = input("请输入库名：")4 print("网址为：%s%s%s"%(yyx1,yyx3,yyx2)) 5：练习字符串的+,*,in,len(),eval()
1 print("No!"*3) 2 s="this is "3 t="younger!"4 print(s+t)5 p="hello world!!!"6 for i in range(len(s)):7 print(i,s[i])
