祝大家新年快樂，虎年大吉，諸事順利！

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('成功運行程序') except Exception as e:put_text('運行：錯誤 at %s' % e)

主要使用了pywebio程序，實現了Python的簡陋在線編輯器。
相對C++編輯器就比較復雜，需要調用g++.exe，可能在您的電腦上，就不見得能用了，需要把Dev-C++安裝到我這個位置，程序才可以運行，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('成功運行程序')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('運行：錯誤 at %s' % e)

運行時會報一個錯，不用管它，跟咱們的程序無關。如果不是這個錯，那就是您的程序有BUG。

測試程序，直接運行第一個，輸入一段Python代碼：

maxNumber = 100 numbers = [] min = 2 numberSum = 0 for i in range(1,101):numbers.append(i)while min <= maxNumber:is_prime = Truefor i in range(2,min):if (min % i) == 0:is_prime = Falsebreakif is_prime == True:numbers.remove(min)min += 1 print(numbers)

點擊藍色按鈕，觀察控制臺：


成功。

再測C++，測試代碼如下（C++：畫桃心）：

// 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; }

輸入測試程序并提交，觀察控制臺：

控制臺上多了個大桃心，成功運行。
