題目1.1 ：顯示"welcome to python "

答案：print('welcome to python')

題目1.2：顯示"welcome to python " 五次

答案：print ("welcome to python\n") * 5 #\n表示換行，要是沒有\(zhòng)n的話就會連接在一起

題目1.3:編寫fun，其中fun是分別有fun組成。

答案：#注意，"N"，"N"和”NN"長度不一致

print ("F"*7," "*3,"U"," "*5,"U"," "*3,"N"*2," "*4,"N"*2)

print ("F"*2," "*4," "*3,"U"," "*5,"U"," "*3,"N"*3," "*3,"N"*2)

print ("F"*7," "*3,"U"," "*5,"U"," "*3,"N"*2,"","N"*1," "*1,"N"*2)

print ("F"*2," "*4," "*3,"","U"," "*3,"U"," "*4,"N"*2," "*2,"N","N"*2)

print ("F"*2," "*4," "*5,""*3,"U"*3," "*2," "*3,"N"*2," "*3,"N"*3)

題目1.4：編寫程序顯示下面的表格（類似矩陣）

答案：#二位數(shù)和兩位數(shù)的長度不一樣，要根據(jù)數(shù)據(jù)的長度調(diào)整空格的長度

value= [1,2,3,4]

print ("a", " "*2, "a^2"," "*2,"a^3"," "*4,)

print ("1", " "*2, "1"," "*5,"1"," "*4)

print ("3", " "*2, "9"," "*5,"27"," "*4)

print ("4", " "*2, "16"," "*4,"64"," "*4)

題目：1.5編寫程序顯示下面表達式的結(jié)果：（9.5*4.5-2.5*3）/（45.5-3.5）

答案：print((9.5*4.5-2.5*3)/(45.5-3.5))

要是加上雙引號，即：

print("(9.5*4.5-2.5*3)/(45.5-3.5)")

那顯示的是這個公式（9.5*4.5-2.5*3）/（45.5-3.5）

題目1.6 ：級數(shù)求和，編寫程序顯示1+2+3+4+5+6+7+8+9的和

答案： #for之后那一列（可能是幾列）要縮進

sum = 0

for i in range(10)

sum+=i

print ( sum)

題目1.7 ：（近似Π）可以使用下面的公式計算Π=4*（1-1/3+1/5-1/7+1/9-1/11+...），編寫程序顯示4*（1-1/3+1/5-1/7+1/9-1/11）和4*（1-1/3+1/5-1/7+1/9-1/11+1/13-1/15）

答案：#**表示次方

程序1：

pi = 0.0

for i in range(1,6):

pi += 4*(((-1)**(i+1))/(2*i-1))

print (pi)

程序2：

pi = 0.0

for i in range(1,8):

pi += 4*(((-1)**(i+1))/(2*i-1))

print (pi)

1.8

顯示r=5.5的圓的面積和周長。

1.9；1.10；1.11不會

1.12

程序：#求更加簡單的分享

import turtle

turtle.forward(100)

turtle.right(90)

turtle.forward(100)

turtle.right(90)

turtle.forward(200)

turtle.right(90)

turtle.forward(200)

turtle.right(90)

turtle.forward(200)

turtle.right(90)

turtle.forward(100)

turtle.right(90)

turtle.forward(200)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.forward(100)

turtle.left(90)

turtle.forward(200)

turtle.left(180)

turtle.forward(100)

程序2：

import turtle

turtle.penup()

turtle.goto(-50,0)

turtle.pendown()

turtle.forward(100)

turtle.penup()

turtle.goto(0,50)

turtle.right(90)

turtle.pendown()

turtle.forward(100)

程序3：#注意轉(zhuǎn)折處的角度

import turtle

turtle.right(60)

turtle.forward(100)

turtle.right(120)

turtle.forward(100)

turtle.right(120)

turtle.forward(100)

程序4：

import turtle

turtle.right(60)

turtle.forward(100)

turtle.right(120)

turtle.forward(100)

turtle.right(120)

turtle.forward(200)

turtle.left(120)

turtle.forward(100)

turtle.left(120)

turtle.forward(100)

好無聊，改天再畫
