课程：《Python程序设计》
班级： 2333班
姓名：周浩然
学号：20233324
实验教师：王志强
实验日期：2024年3月27日
必修/选修：公选课

一、实验内容

设计并完成一个完整的应用程序，完成加减乘除模等运算，功能多多益善。

考核基本语法、判定语句、循环语句、逻辑运算等知识点

二、实验要求

创建工程项目，使用Python语言实现具体的操作运算，并完成程序调试和运行，代码托管到码云。

注：在华为ECS服务器(OpenOuler系统)和物理机(Windows/Linux系统)上使用VIM、IDLE、Pycharm等工具编程实现。

三、实验内容及结果

（1）完整实验代码：
设计了两个功能可以供用户选择使用：1.计算器功能 2.随机加减乘除题目及计分

import math
import random

def sum(a, b):
    return (a + b)

def sub(a, b):
    return (a - b)

def mul(a, b):
    return (a * b)

def div(a, b):
    if b ==0:
        print("0不能做除数")
        return b
    return round((a / b), 2)

def mod(a, b):
    return(a % b)

def pysin(a):
    return math.sin(a)

def pycomplex(a,b):
    complexOper = input("请输入复数的运算：+ - * /")
    if complexOper == "+":
        print("a + b = ",a+b)
        return a + b
    elif complexOper == "-":
        print("a - b = ",a-b)
        return a - b
    elif complexOper == "*":
        print("a * b = ",a*b)
        return a * b
    elif complexOper == "/":
        print("a / b = ",a/b)
        return a/b

def pylog(a):
    return math.log10(a)
def pylog_a_b(a,b):
    return math.log(b) / math.log(a)
