1. 统计字符串(Python3)
题目:输入一个字符,分别编译统计出其中英文字母、空格、数字和其他字符的个数。
1.程序分析:利用while语句,条件为输入的字符不为'\n'
isdigit() 判断是否是数字
isalpha() 判断是否是字母
isalnum() 判断是否是字母和数字组合
#!/usr/bin/env python # -*- coding:utf-8 -*- # @Time: 2018-01-24 11:40 # @Author: Feng Xiaoqing # @File: string.py status = 1 while status: string = input("please input a string('quit'will exit): ") if string == 'quit': exit(1) disgit = pha = space = other = 0 for i in string: if i.isdigit(): disgit += 1 elif i.isalpha(): pha += 1 elif i.isspace(): space += 1 else: other += 1 print("数字:{0},字母:{1},空格:{2},其他:{3}".format(disgit,pha,space,other))
2.乘法口诀(Python3)
乘法口诀:
#!/usr/bin/env python # -*- coding:utf-8 -*- # @Time: 2018-01-24 11:57 # @Author: Feng Xiaoqing # @File: chengfakoujue.py for i in range(1,10): #行 for j in range(1,i+1): chengJi = i*j print("{0} x {1} = {2} ".format(j,i,chengJi),end='') print() 或: for i in range(1,10): for j in range(1,i+1): chengJi = i*j print("{0} x {1} = {2} ".format(j,i,chengJi),end='') if i == j: print()
