条件、循环、函数定义

1.用循环画五角星

import turtle
turtle.setup(600,400,0,0)
turtle.color("yellow")
turtle.bgcolor('red')
turtle.fillcolor("yellow")
turtle.up()
turtle.goto(-250,75)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(100)
    turtle.right(144)
turtle.end_fill()

2.用循环画同心圆

from turtle import*
for i in range(5):
    up()
    goto(0,-20*(i))
    down()
    circle(20*i)

3.用while循环画太阳花

from turtle import*

color('red','blue')
begin_fill()
while True:
    forward(200)
    left(170)
    if (abs(pos()))<1:
        break
end_fill()
done()

4.用函数定义画五个五角星

import turtle
turtle.setup(600,400,0,0)
turtle.color("yellow")
turtle.bgcolor('red')
turtle.fillcolor("yellow")
turtle.up()
turtle.goto(-250,75)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(100)
    turtle.right(144)
turtle.end_fill()

turtle.up()
turtle.goto(-100,-10)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(50)
    turtle.left(144)
turtle.end_fill()

turtle.up()
turtle.goto(-50,50)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

turtle.up()
turtle.goto(-50,120)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(50)
    turtle.right(144)
turtle.end_fill()

turtle.up()
turtle.goto(-100,160)
turtle.down()
turtle.begin_fill()
for i in range(5):
    turtle.forward(50)
    turtle.left(144)
turtle.end_fill()

turtle.color("red")

5.用函数定义画钻石花瓣的太阳花

import turtle

def draw_diamond(brad):
    brad.forward(100)
    brad.right(45)
    brad.forward(100)
    brad.right(135)

def draw_art():
    
    window=turtle.Screen()
    window.bgcolor("purple")
    
    brad=turtle.Turtle()
    brad.shape("turtle")
    brad.color("orange")
    brad.speed("fastest")


    for i in range(0,36):
        draw_diamond(brad)
        draw_diamond(brad)
        brad.left(10)

    brad.right(90)
    brad.forward(155)
    brad.color('green')
    brad.forward(145)

    window.exitonclick()

draw_art()
输入学号，识别年级、专业、序号

name = input("请输入名字：")
num = input("请输入学号：")
print("{}同学您好。".format(name))
print("您的年级为：{}级".format(num[0:4]))
if(int(num[8:10])==43):
    print("您的班级为：网络工程1班")
elif(int(num[8:10])==44):
    print("您的班级为：网络工程2班")
elif(int(num[8:10])==41):
    print("您的班级为：软件工程1班")
elif(int(num[8:10])==42):
    print("您的班级为：软件工程2班")
print("您的序号为：{}".format(num[-2:]))

 输入1-7的数字，输出对应的“星期几”。

s="星期一星期二星期三星期四星期五星期六星期天"
a=int(input("请输入(1-7)："))
if(0<a<8):
    print(s[-3+3*a:0+3*a])
else:
    print("输入有误。")

 识别身份证号中的省市区、年龄、性别。

ID=input('请输入您的身份证号码：')

P=['广东省','四川省']
C=['广州市','深圳市','成都市']
R=['越秀区','白云区','天河区','福田区','南山区','罗湖区']

p=int(ID[0:2])
c=int(ID[2:4])
r=int(ID[4:6])
sex=int(ID[16])
age=int(ID[6:10])

if p==44:
    print("您所属的省：",P[0])
elif p==51:
    print("您所属的省：",P[1])
else:
    print('查无数据。')

if p==44:
    if c==1:
        print(C[0])   
        if r==4:
            print(D[0])
        elif r==11:
            print(D[1])
        elif  r==6:
            print(D[2])
        else:
             print('无数据。')
    elif c==3:
        if r==4:
            print(D[3])
        elif r==5:
            print(D[4])
        elif  r==3:
            print(D[5])
        else:
            print('无数据。')
    else:
        print('无数据。')

if p==51:
    if c==1 and r==8:
        print(C[2],R[6])
    else:
        print('无数据。')

if sex%2==0:
    print('女性')
else:
    print('男性')

age=2017-int(age)
print('您今年{}岁'.format(age))
