1.Hello World！

print('hello world!'

2.簡單交互

name=input('輸入姓名：') print('{}好'.format(name)) print('{}好'.format(name[0])) print('{}好'.format(name[1:]))

?

3.用戶輸入兩個數(shù)字，計算并輸出兩個數(shù)字之和

print(float(input('第1個數(shù)：'))+float(input('第2個數(shù)：')))

4。用戶輸入三角形三邊長度，并計算三角形的面積：（海倫公式）

a=float(input('第一條邊長：')) b=float(input('第2條邊長：')) c=float(input('第3條邊長：')) p=(a+b+c)/2 s=(p*(p-a)*(p-b)*(p-c))**0.5 print(s)

5.輸入半徑，計算圓的面積

?

r=float(input('半徑：')) s=3.14*r*r print('面積是：',s)

6.畫一組同切圓

import turtle turtle.circle(10) turtle.circle(20) turtle.circle(40) turtle.circle(80)

7.畫一個五角星

import turtle turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300)

?

8.畫一個全黃色的五角星

import turtle turtle.color('yellow') turtle.begin_fill() turtle.fillcolor('yellow') turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.left(144) turtle.forward(300) turtle.end_fill()

?9.同心圓

import turtle turtle.penup() turtle.goto(0,-200) turtle.pendown() turtle.circle(200) turtle.penup() turtle.goto(0,-150) turtle.pendown() turtle.circle(150) turtle.penup() turtle.goto(0,-100) turtle.pendown() turtle.circle(100) turtle.penup() turtle.goto(0,-50) turtle.pendown() turtle.circle(50)

?10.國旗

import turtle turtle.bgcolor('red') turtle.color('yellow') turtle.begin_fill() turtle.fillcolor('yellow') turtle.penup() turtle.goto(-310,200) turtle.pendown() for i in range(5):turtle.forward(150)turtle.right(144) turtle.end_fill() turtle.penup() turtle.goto(-150,250) turtle.pendown() turtle.begin_fill() for i in range(5):turtle.forward(40)turtle.right(144) turtle.end_fill() turtle.penup() turtle.goto(-100,200) turtle.pendown() turtle.begin_fill() for i in range(5):turtle.forward(40)turtle.right(144) turtle.end_fill() turtle.penup() turtle.goto(-110,130) turtle.pendown() turtle.begin_fill() for i in range(5):turtle.forward(40)turtle.right(144) turtle.end_fill() turtle.penup() turtle.goto(-160,70) turtle.pendown() turtle.begin_fill() for i in range(5):turtle.forward(40)turtle.right(144) turtle.end_fill()
