'sqlite3.Cursor' object has no attribute '__getitem__' Error in Python Flask


'sqlite3.Cursor' object has no attribute '__getitem__' Error in Python Flask

I hope this helps . __getitem__ refers to square bracket access, in this case data[0]. The error tells you that you can't use cursors like that. Replace data[0] with the value returned from data.fetchone().

help you fix your problem Probably, there is no element in your Records table. Therefore, cur.fetchone() returns None so you're effectively trying to access None[0], hence the error message.
The error message by the way is telling you that you take [0] of something which is None, so if you look at the line, the only thing that you're taking [0] of is number. So a good way to debug such problems is to add something like print number before the offending line, this often challenges some fundamental believes I have about the contents of my variables :)

wish of those help It seems as though y_in is not a list but a float value. The error rises because you're trying to get an item with obj[x] of an object which doesn't support it.
Looking at the documentation for odeint it says that the input function should take two arguments, the first being your data object and the second should be a float. Your implementation of f_func is therefore wrong.

This might help you To access an element of a list, use square brackets. To instantiate a class, use parens.
In other words, do not use:
code :
print Ordering[('A', 'B'), ('C', 'B'), ('D', 'A')]
print Ordering((('A', 'B'), ('C', 'B'), ('D', 'A')))
class HasItems(object):
    def __getitem__(self, key):
        return key**2
>>> a = HasItems()
>>> a[4]
16

wish of those help Doh! The data isn't being sent to the server properly! I've rewritten some of your code below. I hope you don't mind, but the form will now submit with ordinary post variables instead of JSON.
code :
@app.route('/details', methods=['GET', 'POST'])
def details():
    # This is our new method, notice it's a bit streamlined.

    if request.method == "POST":
        # We can get the post data using request.form.get(). The first variable is the name="" attribute in HTML, and the second is the default value if it wasn't found in the data.
        return "The address was %s" % request.form.get('address', 'not provided! :O')
    return render_template("base.html")
$(document).ready(function() {
$("#submitForm").click(function(e){

    // Prevent the HTML page from submitting the form since we're doing this by AJAX. This would cause duplications and other issues.
    e.preventDefault();

    // Get a FormData object from the page
    var data = new FormData($('form')[0]);

    // You don't HAVE to send your data by JSON, and in this instance it will be easier not to
    $.ajax({
        type: "POST",
        url: "/details",
        data: data,
        processData: false,
        contentType: false,
        success: function(result) {
            console.log(result)
        }
    })
    })
})

this one helps. I'm trying to interpret data I am planning to send betweeen machines with a chosen target where I will send the data to and the data the following code is supposed to do this(the target is a number of any length and has to start with a "/") I know the whole code isn't great and I am probably using wrong names for pretty much everything but I hope with a bit of help it will work , list.append() is a function
code :
targetstr.append[command[o]]
targetstr.append(command[o])
