蟒蛇代碼可以在Python相互環境在Win7 CMD

-1

from flask import Flask 
from flask import request 

app = Flask(__name__) 

@app.route('/', methods=['GET', 'POST']) 
def home(): 
    return '<h1>Home</h1>' 

@app.route('/signin', methods=['GET']) 
def signin_form(): 
    return '''<form action="/signin" method="post"> 
       <p><input name="username"></p> 
       <p><input name="password" type="password"></p> 
       <p><button type="submit">Sign In</button></p> 
       </form>''' 

@app.route('/signin', methods=['POST']) 
def signin(): 
    if request.form['username']=='admin' and request.form['password']=='password': 
     return '<h3>Hello, admin!</h3>' 
    return '<h3>Bad username or password.</h3>' 

if __name__ == '__main__': 
    app.run()

它可以在Python相互環境中成功執行，但未能在Win7 CMD作爲一個文件來執行app.py. 例1：複製代碼並粘貼到Python交互環境如下：

* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

例2：複製代碼，讓他們保存爲一個名爲「hsiehapp.py」文件

AttributeError: module 'numbers' has no attribute 'Number'

我的Python版本是蟒蛇3.6.1。我的操作系統是windows7。我對此很困惑，請幫助我。謝謝...

'AttributeError：module'numbers'沒有屬性'Number''這個錯誤表明你當前目錄中有一個'numbers.py'模塊，它沒有任何定義爲'Number'，我想你想導入標準庫模塊'數字'。 – 0decimal0

是的，你是對的，非常感謝你！ –

此錯誤

AttributeError: module 'numbers' has no attribute 'Number'

表明，有在當前目錄下一個numbers.py模塊，它已沒有定義爲Number，我想你想導入標準庫模塊numbers。

將該模塊重命名爲其他內容，然後可以使用標準庫模塊。
