When calling the api to output data, the
label will appear, see screenshot. How to clear it?

I am making a form, the following is the code for the output page

@app.route('/search4', methods=['POST']) def do_search() -> 'html': hero_name = request.form['input_hero_name'] output_prompt_error = '请输入正确的英雄名' dict_hero = get_dict_hero(hero_name) if 'error' in dict_hero: return render_template('entry.html', the_entry_title='英雄联盟英雄信息', the_output_prompt_error=output_prompt_error, ) else: return render_template('results.html', the_name=hero_name, output_skill_passive_name = dict_hero['data'][0]['passive']['name'], output_skill_passive_description = dict_hero['data'][0]['passive']['description'], output_skill_1_name = dict_hero['data'][0]['spells'][0]['name'], output_skill_1_tooltip = dict_hero['data'][0]['spells'][0]['tooltip'], output_skill_2_name = dict_hero['data'][0]['spells'][1]['name'], output_skill_2_tooltip = dict_hero['data'][0]['spells'][1]['tooltip'], output_skill_3_name = dict_hero['data'][0]['spells'][2]['name'], output_skill_3_tooltip = dict_hero['data'][0]['spells'][2]['tooltip'], output_skill_4_name = dict_hero['data'][0]['spells'][3]['name'], output_skill_4_tooltip = dict_hero['data'][0]['spells'][3]['tooltip'], )
