直接奔入主题看下面pywebio
程序,实现了python的简陋在线编辑器
from pywebio.input import * from pywebio.output import put_text from os import system,remove try: code = textarea('code edit online', code={'mode': "python",'theme': 'darcula'}, value='# input your code here\n') with open('temp.py','w',encoding = 'utf-8') as f: f.write(code) system('python temp.py') put_text('成功运行程序') except exception as e: put_text('运行:错误 at %s' % e)
主要使用了pywebio
程序,实现了python的简陋在线编辑器。
相对c++编辑器就比较复杂,需要调用g++.exe,可能在您的电脑上,就不见得能用了,需要把dev-c++安装到我这个位置,程序才可以运行,您可以修改程序。
from pywebio.input import * from pywebio.output import put_text from sys import path from os import system,remove try: system('chcp 65001 >nul') code = textarea('code edit online ( c++ )', code={'mode': "python",'theme': 'darcula',}, value='// input your code here.\n') with open('temp.cpp','w',encoding='utf-8') as f: f.write(code) put_text('成功运行程序') system(r'd:\dev-c++\dev-cpp\mingw64\bin\g++.exe "%s\temp.cpp" -o "%s\temp.exe" && call "%s\temp.exe" && pause' % (path[0],path[0],path[0])) remove('temp.cpp') remove('temp.exe') except exception as e: put_text('运行:错误 at %s' % e)
运行时会报一个错,不用管它,跟咱们的程序无关。如果不是这个错,那就是您的程序有bug
。
from pywebio.input import * from pywebio.output import put_text from sys import path from os import system,remove try: system('chcp 65001 >nul') code = textarea('code edit online ( c++ )', code={'mode': "python",'theme': 'darcula',}, value='// input your code here.\n') with open('temp.cpp','w',encoding='utf-8') as f: f.write(code) put_text('成功运行程序') system(r'd:\dev-c++\dev-cpp\mingw64\bin\g++.exe "%s\temp.cpp" -o "%s\temp.exe" && call "%s\temp.exe" && pause' % (path[0],path[0],path[0])) remove('temp.cpp') remove('temp.exe') except exception as e: put_text('运行:错误 at %s' % e)
测试程序,直接运行第一个,输入一段python代码:
maxnumber = 100 numbers = [] min = 2 numbersum = 0 for i in range(1,101): numbers.append(i) while min <= maxnumber: is_prime = true for i in range(2,min): if (min % i) == 0: is_prime = false break if is_prime == true: numbers.remove(min) min += 1 print(numbers)
点击蓝色按钮,观察控制台:
成功。
再测c++,测试代码如下(c++:画桃心):
// author:pandaoxi #include <iostream> using namespace std; int main(){ for(double y=1.5;y>-1.5;y-=0.1){ for(double x=-1.5;x<1.5;x+=0.05){ double a=x*x+y*y-1; char b=(a*a*a-x*x*y*y*y<=0.0?'*':' '); cout<<b; } cout<<endl; } return 0; }
输入测试程序并提交,观察控制台:
控制台上多了个大桃心,成功运行。
