這篇文章給大家分享的是有關python代碼運行助手的使用方法的內容。小編覺得挺實用的,因此分享給大家做個參考。一起跟隨小編過來看看吧。
python代碼運行助手是能在網頁上運行python語言的工具。因為python的運行環境在很多教程里都是用dos的,黑乎乎的界面看的有點簡陋,所以出了這python代碼運行助手,作為ide。
實際上,python代碼運行助手界面只能算及格分,如果要找ide,推薦使用jupyter。jupyter被集成到ANACONDA里,只要安裝了anacoda就能使用了。
1、要打開這運行助手首先要下載一個learning.py,如果找不到可以復制如下代碼另存為“learning.py”,編輯器用sublime、或者notepad++。
#!/usr/bin/env python3 # -*- coding: utf-8 -*- r''' learning.py A Python 3 tutorial from http://www.liaoxuefeng.com Usage: python3 learning.py ''' import sys def check_version(): v = sys.version_info if v.major == 3 and v.minor >= 4: return True print('Your current python is %d.%d. Please use Python 3.4.' % (v.major, v.minor)) return False if not check_version(): exit(1) import os, io, json, subprocess, tempfile from urllib import parse from wsgiref.simple_server import make_server EXEC = sys.executable PORT = 39093 HOST = 'local.liaoxuefeng.com:%d' % PORT TEMP = tempfile.mkdtemp(suffix='_py', prefix='learn_python_') INDEX = 0 def main(): httpd = make_server('127.0.0.1', PORT, application) print('Ready for Python code on port %d...' % PORT) httpd.serve_forever() def get_name(): global INDEX INDEX = INDEX + 1 return 'test_%d' % INDEX def write_py(name, code): fpath = os.path.join(TEMP, '%s.py' % name) with open(fpath, 'w', encoding='utf-8') as f: f.write(code) print('Code wrote to: %s' % fpath) return fpath def decode(s): try: return s.decode('utf-8') except UnicodeDecodeError: return s.decode('gbk') def application(environ, start_response): host = environ.get('HTTP_HOST') method = environ.get('REQUEST_METHOD') path = environ.get('PATH_INFO') if method == 'GET' and path == '/': start_response('200 OK', [('Content-Type', 'text/html')]) return [b'<html><head><title>Learning Python</title></head><body><form method="post" action="/run"> <textarea name="code" style="width:90%;height: 600px"></textarea><p><button type="submit">Run</button> </p></form></body></html>'] if method == 'GET' and path == '/env': start_response('200 OK', [('Content-Type', 'text/html')]) L = [b'<html><head><title>ENV</title></head><body>'] for k, v in environ.items(): p = '<p>%s = %s' % (k, str(v)) L.append(p.encode('utf-8')) L.append(b'</html>') return L if host != HOST or method != 'POST' or path != '/run' or not environ.get('CONTENT_TYPE', '').lower(). startswith('application/x-www-form-urlencoded'): start_response('400 Bad Request', [('Content-Type', 'application/json')]) return [b'{"error":"bad_request"}'] s = environ['wsgi.input'].read(int(environ['CONTENT_LENGTH'])) qs = parse.parse_qs(s.decode('utf-8')) if not 'code' in qs: start_response('400 Bad Request', [('Content-Type', 'application/json')]) return [b'{"error":"invalid_params"}'] name = qs['name'][0] if 'name' in qs else get_name() code = qs['code'][0] headers = [('Content-Type', 'application/json')] origin = environ.get('HTTP_ORIGIN', '') if origin.find('.liaoxuefeng.com') == -1: start_response('400 Bad Request', [('Content-Type', 'application/json')]) return [b'{"error":"invalid_origin"}'] headers.append(('Access-Control-Allow-Origin', origin)) start_response('200 OK', headers) r = dict() try: fpath = write_py(name, code) print('Execute: %s %s' % (EXEC, fpath)) r['output'] = decode(subprocess.check_output([EXEC, fpath], stderr=subprocess.STDOUT, timeout=5)) except subprocess.CalledProcessError as e: r = dict(error='Exception', output=decode(e.output)) except subprocess.TimeoutExpired as e: r = dict(error='Timeout', output='執行超時') except subprocess.CalledProcessError as e: r = dict(error='Error', output='執行錯誤') print('Execute done.') return [json.dumps(r).encode('utf-8')] if __name__ == '__main__': main()
2、再用一個記事本寫如下的代碼:
@echo off python learning.py pause
另存為‘運行.bat’
3、把“運行.bat”和“learning.py”放到同一目錄下。
4、雙擊運行“運行.bat",之后會彈出黑色的dos窗口,這個窗口不要關閉。
5、輸入網址對應的網址和端口,整個過程就完成了。
