Question

有些代码可以被忽略，我试图把str变成int，而这样做我似乎得到了这个错误。＆＃39; INT＆＃39;对象不可调用

llb和lw在本节的代码中没有提到代码中的任何其他地方。它是第一次也是唯一一次。

我现在一直在为此而烦恼，似乎无法解决这个问题。此错误的任何其他内容似乎都与我的错误相同。

llb通常设置为一个简单的东西，如帖子

@app.route('/printlab', methods=['POST'])
def printlab():
 if request.method == 'POST':
     lfname = request.form['first_name']
     llname = request.form['last_name']
     lstate = request.form['state']
     lcity = request.form['city']
     laddress = request.form['shipping_address']
     lzip = request.form['zip']
     llb = request.form['lbs']
     loz = request.form['ozs']
     lw = (int(llb)*16)
     return lw

视图函数应该返回模板渲染调用，重定向或其他类型的HTML响应。你的函数返回一个普通的整数。

此返回值正被传递到Flask框架，该框架无法处理它。

str to int issue＆＃39; int＆＃39;当var设置为乘法时，对象不可调用
