Python写一个简单的在线编辑器

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。
