熊猫DF的字典列表-“ NoneType”对象没有属性“键”

Question

我想将字典列表转换为熊猫DF。一排看起来像这样：{'id': 5102, 'lat': 41.9258689, 'lng': -91.4231934}

当我查看type（）时，我得到了int, float, float

temp_df = pd.DataFrame(geocode_list)

然后我得到了错误：AttributeError: 'NoneType' object has no attribute 'keys'

我不知道是什么原因引起的。

Answer 1

如果您的字典不包含None，那么它将起作用：-

pd.DataFrame(list(geocode_list.items()), columns=['id', 'lat','lang'])

产生了可能的问题，请检查以下修复程序：

// Create your popup with an menu option to switch to textselection modus:
PopupMenu popup = new PopupMenu(mCtx, view);
popup.inflate(R.menu.text_options_menu);
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {
        switch (item.getItemId()) {
            case ...
            case R.id.text_textisselectable:
                view.setOnTouchListener(null);
                ((TextView)view).setTextIsSelectable( true);
                ((TextView)view).setFocusable( true);
                ((TextView)view).setLongClickable( true);
                // Install a click listener to switch back to the previous Touch Listener
                ((TextView)view).setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        PopupMenu popupx = new PopupMenu(mCtx, view);
                        popupx.inflate(R.menu.selecttext_back_menu);
                        popupx.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                            @Override
                            public boolean onMenuItemClick(MenuItem item) {
                                ((TextView)view).setTextIsSelectable( false);
                                ((TextView)view).setFocusable( false);
                                ((TextView)view).setLongClickable( false);
                                view.setOnTouchListener(onTouchListener);
                                return true;
                            }});
                            popupx.show();
                        }
                    });
                break;
