練習??輸入三條邊長如果能構成三角形就計算周長和面積

import math a,b,c = input().split(',') a = float(a) b = float(b) c = float(c) if a + b > c and a + c > b and b + c > a:print('周長%f'%(a + b + c))p = (a + b + c)/2area = math.sqrt( p * ( p - a ) * ( p - b )*( p - c )) print('面積%f'%(area)) else:print('不能構成三角形')

　　練習 求平均值

flag = 0 sum = 0 while 1:print('Enter an integer, the input ends if it is 0: ')shu = input()if shu != '0' :sum = sum + float(shu)flag +=1else:break ave = float(sum/flag) print('平均值是%f' %ave)

　　練習 個人所得稅計算器

salary = float(input('本月收入: ')) insurance = float(input('五險一金: ')) diff = salary - insurance - 3500 if diff <= 0:rate = 0deduction = 0 elif diff < 1500:rate = 0.03deduction = 0 elif diff < 4500:rate = 0.1deduction = 105 elif diff < 9000:rate = 0.2deduction = 555 elif diff < 35000:rate = 0.25deduction = 1005 elif diff < 55000:rate = 0.3deduction = 2755 elif diff < 80000:rate = 0.35deduction = 5505 else:rate = 0.45deduction = 13505 tax = abs(diff * rate - deduction) print('個人所得稅: ￥%.2f元' % tax) print('實際到手收入: ￥%.2f元' % (diff + 3500 - tax))

　　生成隨機驗證碼

驗證碼 import random import numpy as np import string print('開始生成驗證碼') s = string.ascii_lowercase str1 = "" for i in range (3):for i in range(0,4):a = random.choice(s)b = np.random.choice([1,2,3,4,5,6,7,8,9,0])c = random.choice([a,b])print(c,end="")str1 = str(str1)+str(c) print('')shuru = input('請輸入驗證碼')if shuru == str1 :print('成功')breakelse:print('再試一次')

　　密碼爆破

import itertools username = 'admin' print('輸入一個6位以內純數字密碼') password = int(input()) print('開始爆破') for i in range (0,999999):print(i)if int(i) == password:print('爆破成功，密碼%s' %i)breakelse:continue

　　石頭剪子布

import numpy as np res = np.random.choice(['0','1','2']) x=input('輸入0、剪刀 1、石頭 2、布') if res=='0':if x=='0':print("tie")elif x=='1':print('loser')else:print('win') elif res=='1':if x=='2':print("win")elif x=='0':print('tie')else:print('loser') else:if x=='2':print("loser")elif x=='1':print('win')else:print('tie')
