Python 实验案例3

Code:

import re
str = "The quick brown box jumped over the lazy dog. An apple a day keeps the doctor away. Can a fox and a dog be friends?"
str1=str.lower()
dict = {}#创建空字典
list =re.split('[s,?]',str1)#分隔字符串
for i in list:
    dict[i]=list.count(i) #将分割后的列表元素作为key，统计元素的数量作为value
dict_sort = sorted(dict.items(), key=lambda d: d[1], reverse=True)#对value降序排序
print(dict_sort)

Code:

# -*- coding: utf-8 -*-
import numpy as np
import random
import os


def rand_sound():
    num= random.randint(1,8)
    os.system(r'E:music\'+str(num)+'.mp3')
    #print(r'E:music\'+str(num)+'.mp3')
    return num


#判断是否正确
def main():
    result = rand_sound()
    guess = int(input("请输入猜测音高数值(1-7):"))
    while(True):
        if(guess==result):
            print("猜对了")
            break
        elif(guess>result):
            print("猜大了")
            guess = int(input("请输入猜测音高数值(1-7):"))
            continue
        elif(guess 
3. 定义一个函数，该函数有1个参数，函数被调用时，传递给函数一个整数，函数可返回该整数的中文形式，例如传递给函数一个整数1，函数可返回汉字“壹”。 
Code:
 
# -*- coding: utf-8 -*-
def number(num):
    str1='0123456789'
    str2 = '零壹贰叁肆伍陆柒捌玖'
    dic=dict(zip(str1,str2))
    list=[]
    for i in str(num):
        list.append(dic[i])
    return ''.join(list)#列表转字符串

if __name__ == "__main__":
    nums=int(input("请输入一串数字：n"))
    result=number(nums)
    print(result)
