Python 类型错误：不可损坏的类型：'；设置'；烧瓶状

我正在尝试从Flask中的表单获取数据：

app.py

@app.route('/newProjectCreation/', methods=['GET', 'POST'])
def newProjectCreation():
    try:
        if request.method == 'POST':
            # Data Fetch from Models Form
            name = request.form['modelName']
            modelDescription = request.form['modelDescription']
            inputType = request.form.getlist['inputType[]']
            outputType = request.form.getlist['outputType[]']
            model = request.files['model']
            modelLanguage = request.form['modelLanguage']

HTML

这是一个简单的表单（不是Flask WTF表单），字段“inputType”和“outputType”应该按原样返回数组

错误：

Traceback (most recent call last):
  File "/home/adiagarwal/cad/flaskapp-docker/flaskapp/app.py", line 106, in newProjectCreation
    inputType = request.form.getlist['inputType[]']
TypeError: 'method' object is not subscriptable

During handling of the above exception, another exception occurred:

我之前没有js方面的经验，我正在学习，如果可能，请简化回答

提前谢谢。

好的，我关注的是一个大问题，但问题太简单了，我没有意识到：用

（）

替换所有

[]

。见下文

如果您

[]

它假定为

dict

，并且您正在重新跟踪列表或集合

    @app.route('/newProjectCreation/', methods=['GET', 'POST'])
    def newProjectCreation():
        try:
            if request.method == 'POST':
                # Data Fetch from Models Form
                name = request.form('modelName')
                modelDescription = request.form('modelDescription')
                inputType = request.form.getlist('inputType[]')
                outputType = request.form.getlist('outputType[]')
                model = request.files('model')
                modelLanguage = request.form('modelLanguage')

您正试图在Python中使用

set

作为dict中的键。

set

不能用作哈希值。那么，我应该怎么做呢？事实上，我不明白你的回答。请将完整错误分享到错误产生的确切位置。此外，请检查Python中的

集合是什么，以及它们是否可hasable。根据此->：集合是不可哈希的，集合是可变的，它们是不可哈希的。您好，谢谢，我尝试了解决方案，但有一点变化：所有的
[]
都不会被替换为
（）
它只是用于“inputType”和“outputType”字段这将被更改。但是现在在我获取文件输入的那一行（最后第二行）出现了另一个问题。请共享错误。没有人可以预测错误，因为您没有共享[MRC]（）第二个错误-->请检查并提供建议。
