1、乘法表
#! -*- coding:utf-8 -*- for i in range(1,10): for j in range(1,i+1): print(‘%d*%d=%d\t‘ % (i, j, i*j)), print‘\r‘
1*1=1
2*1=2 2*2=4
3*1=3 3*2=6 3*3=9
4*1=4 4*2=8 4*3=12 4*4=16
5*1=5 5*2=10 5*3=15 5*4=20 5*5=25
6*1=6 6*2=12 6*3=18 6*4=24 6*5=30 6*6=36
7*1=7 7*2=14 7*3=21 7*4=28 7*5=35 7*6=42 7*7=49
8*1=8 8*2=16 8*3=24 8*4=32 8*5=40 8*6=48 8*7=56 8*8=64
9*1=9 9*2=18 9*3=27 9*4=36 9*5=45 9*6=54 9*7=63 9*8=72 9*9=81
2、回文数
#! -*- coding:utf-8 -*- num = raw_input(‘请输入一个整数： ‘) for i in range(len(num)/2): if num[i] == num[-i-1]: print(‘%s 是一个回文数‘ % num) else: print(‘%s 不是一个回文数‘ % num)
3、阶乘
#! -*- coding:utf-8 -*- def f(n): if n < 0: print(‘负数没有阶乘‘) elif n == 0: return 1 elif n == 1: return 1 else: return n*f(n-1) def jiesum(n): sum = 0 for i in range(1, n+1): sum += f(i) return sum number = int(raw_input(‘请输入一个整数： ‘)) result = f(number) sum = jiesum(number) print(‘%d 的阶乘是%d‘ % (number, result)) print(‘%d 的阶乘和是%d‘ % (number, sum))
4、字符串去重
#! -*- coding:utf-8 -*- # 字符串去重 str = ‘zhang jingjing‘ lst = [] for i in str: if i not in lst: lst.append(i) print ‘‘.join(lst) # 把字符串sign替换成空格 str1 = ‘title=华为招聘会&time=20190305&sign=zhang&name=jing‘ lst1 = [] for i in str1.split(‘&‘): if i.startswith(‘sign=‘): lst1.append(‘sign= ‘) else: lst1.append(i) print ‘&‘.join(lst1)
5、冒泡排序法
#! -*- coding:utf-8 -*- # list = [1,5,4,78] # n个数比n-1轮 # 1 - n-1-1 # i n-i-1 num = raw_input(‘输入一组数： ‘) # print(num) str list = num.split(‘,‘) # list # list = list(num) print(list) for i in range(len(list)-1): for j in range(len(list)-i-1): if list[j]>list[j+1]: list[j],list[j+1] = list[j+1],list[j] print(list)
6、自动生成扑克牌，输入1随机发一张牌，输入2随机发2张牌。。。输入0停止发牌并把之前的牌全部返回
#! -*- coding:utf-8 -*- import random def auto(): pokers = [] poker = [] list1 = [‘R‘, ‘B‘, ‘F‘, ‘M‘] list2 = [‘A‘, 2, 3, 4, 5, 6, 7, 8, 9, 10, ‘J‘, ‘K‘, ‘Q‘] for i in list1: for j in list2: poker.append(i) poker.append(j) pokers.append(poker) poker = [] pokers.append([‘bighero‘]) pokers.append([‘smallhero‘]) # random.shuffle(pokers) return pokers def fapai(poker, n): if n != 0: return random.sample(poker, n) else: print(‘请输入一个整数‘) pokers = auto() print(pokers) result = [] while True: number = int(raw_input(‘请输入一个整数： ‘)) if number != 0: rand1 = fapai(pokers, number) print(rand1) for i in rand1: result.append(i) else: print(result) break
学习路上的同志共勉！
