1.建立計算BMI指數的模組

def dun_bmi(person,height,weight):
print(person + "的身高" + str(height) + "米\t 體重:" + str(weight) + "千克" )
bmi = weight / (height * height)
print(person + "的bmi指數為： " + str(bmi))

2.匯入兩個包括同名函式的模組

def girth(width,height):
    return (width + height) * 2
def area(width,heigth):
    return width * heigth
if __name__ == '__main__':
    print(area(10,20))
import math
PI = math.pi
def girth(r):
    return round(2 * PI * r , 2)
def area(r):
    return round(PI * r * r , 2)
if __name__ == '__main__':
    print(girth(10))
import rectangle as r
import circular as c
if __name__ == '__main__':
    print("圓形的周長是：", c.girth(10))
    print("矩形的周長是：" , r.girth(10,20))

3.在指定包中建立通用的設定和獲取尺寸的模組

_width = 800
_height = 600
def change(w,h):
    global _width
    _width = w
    global _height
    _height = h
def getWidth():
    global _width
    return _width
def getHeight():
    global  _height
    return _height
from settings.size import *
if __name__ == 'main__':
    change(1024,768)
    print("寬度: ",getWidth())
    print("高度: ",getHeight())

4.生成由數字，字母組成的4位驗證碼

import random
if __name__ == '__main__':
checkcode = ''
for i in range(4):
index = random.randrange(0,4)
if index != i and index+1 != i:
checkcode += chr(random.randint(97,122))
elif index + 1 == i:
checkcode += chr(random.randint(65,90))
else:
checkcode += str(random.randint(1,9))
print("驗證碼： " ,checkcode)

實戰一：

import random
def number():
    a=[random.randint(1,35) for i in range(5)]
    l=[]
    for i in a:
        if i not in l:
            l.append(i)
        else:
            i=random.randint(1,35)
            l.append(i)
        l.sort()
    a=[str(i) for i in l]
    b=[random.randint(1,12) for i in range(2)]
    o=[]
    for i in b:
        if i not in o:
            o.append(i)
        else:
            i=random.randint(1,12)
            o.append(i)
        o.sort()
    b=[str(i) for i in o]
    c=[" "*5]
    for i in range(5):
        if len(a[i])==2:
            for j in range(2):
                if len(b[j])==2:
                    pass
                else:
                    b[j]='0'+b[j]
        else:
            a[i]='0'+a[i]
    g=a+c+b
    for i in g:
        print(i,end=" ")
print("大樂透號碼生成器")
k=int(input("請輸入要生成的大樂透號碼注數："))
for i in range(k):
    number()
    print("")

實戰二：

import sys

sys.path.append(r"D:\Python\python0\python0")

import JiFu
print('開始集福啦~~~')

fu={'愛國福':0,'富強福':0,'和諧福':0,'友善福':0,'敬業福':0}

while  JiFu.five_blessings(fu)==0:
    input('\n按下<Enter>鍵獲取五福')

    Strfu=JiFu.Ji_Fu()[0]

    print('獲取到：' +Strfu)

    fu[Strfu] += 1

    JiFu.fus(fu)
print('\n恭喜您整合五福！！！')



import  random

def Ji_Fu():

    fus=['愛國福','富強福','和諧福','友善福','敬業福']

    fu=random.sample(fus, 1)

    return fu

def fus(fu):
    print('當前擁有的福：')

    for i, j in fu.items():

        print(i,': ',j,'\t',end='')

def five_blessings(fu):

    type=1

    for i, j in fu.items():

        if j==0:

          type=0

    return type;
